Back in the early 80s I had a chance to test a Leicaflex side by side
with my Pentax LX. I shot a series of pictures comparing the following lenses: Leica 35mm - Pentax-M 28mm f2.8 Leica 50mm - Pentax-M 50mm f4 macro Leica 135mm - Pentax-M 100mm f2.8 I cannot remember the Leicaflex model or the maximum apertures of Leica lenses; but they were the ones current at that time. They were supplied by Leica Canada as part of a promotion to "try a Leica for a day" In the hopes that one would buy one. The pictures were taken on Kodachrome 25 for maximum sharpness, and both cameras were mounted on tripods. The first slide on each roll of film was a photograph of the other camera. Both films were processed by Kodak Canada. When the films were processed and returned uncut in strips, I asked the son of the owner of the camera store where I dealt, to choose the Leica slides. He inspected both film strips with a Pentax 20X magnifier and selected one as being shot by the Leicaflex. I then asked him which camera was pictured at the front of the strip. It was the Leicaflex. The pictures he thought were taken by the Leicaflex had been taken by the Pentax LX. His father, who was a bit of a Leicaphile, also inspected the film strips and appeared somewhat upset by the results. At the time of the tests I used Leica Ms for all of my available-light work. Therefore, having no need for high-speed lenses, when I purchased Pentax lenses, they were the slower f2.8 and f4 ones. These ones, I expect, would be easier to correct. Also the pictures were taken outside at around f8, rather than wide open. This was not a definitive test; but it proved to me that, certainly in some areas, the Pentax lenses could hold their own against some of the best. I was happy with the results because the circumstances of the test mirrored the situations in which I expected to use the Pentax and its lenses, outdoors for architectural and other work.

Most lenses are pretty good at f/8. the real test is near maximun
aperture. that's where the Leica lenses would trounce the Pentax optics. Charles Kinghorn wrote: Back in the early 80s I had a chance to test a Leicaflex side by side with my Pentax LX.

"Duncan J Murray" wrote: [SNIP] Some of the "star performers" of the Pentax range actually have a star to let you know which they are, including an outstanding SMC PENTAX-A* 85mm f/1.4 and a 300mm. They tend to sell for big money, but there are other gems too, at lower prices, notably: The 135mm f1.8 A* is another very fine lens in the star series, which continues into the current AF lenses too, with the F* and FA* ranges, whihc both work just as well on manual focus bodies. The 200m f2.8 FA*, in particular, is a wonderful lens. I keep hearing good things about the * lenses, shame I can't afford any of them! 24mm f/3.5 K, 28mm f/2.8 A, 35mm f/2 K and A, 50mm f/1.4 K and A, 50mm f/1.7 M and A, 50mm f/2.0 K, M and A, 105mm f/2.8 M, 200mm f/4 K, M and A. In zooms, I would strongly recommend the 35-105mm f/3.5 A, which offers very good sharpness, low distortion and excellent bokeh. The 70-210mm f/4 A is good but not outstanding. There is also a 28-70mm f/4 autofocus lens that is optically outstanding but costs very little. I'd go along with all of that, except for maybe not feeling that the 200mm f4 is as strong as the others mentioned - except in the A* (macro) version. Others I'd add to the list that I have used and particularly like are the 30mm f2.8 K (not easy to find), 85mm f1.8 K, and the 135mm f2.5 K (not the 'Takumar bayonet' f2.5 version, which is a budget alternative and not nearly so good.) I personally like the 120mm f2.8 as well, but this is also hard to find. The 28mm f3.5 K and 35mm f3.5K are also excellent, and quite light. The rectilinear super-wides are very good too: the 15, 18, and 20 - though none of these is an inexpensive purchase. All the Pentax macro lenses are very good, though the current 100mm f3.5 is a budget alternative to the top-of-the-line f2.8, and is said to perform accordingly - the f2.8 is spectacularly good. Can macro lenses be used for normal photography as well? As in, can they focus on infinity? And how does the picture look using it in this way? I have a number of Pentax zoom lenses, mostly newer ones, and can vouch strongly for the 28-70mm f4 FA AL - it is more or less the optical equal of the f2.8, but at a fraction of the cost, size, and weight. The current 24-90mm is very good too. I don't have a Pentax zoom in the 80-200 range, so can't comment here (I use an Angenieux 70-210 instead, and find it fits well with the 'look' of the Pentax glass.) Oh, well, I do have the 80-320, and it is good for the price and the range, but I only use it when I _really_ need to cover all that range in a single lens, which is not often. 24-90 seems a very nice lens. Very useful focal length range - 24mm is great for landscape, and 90mm for portraits! I have a 35-70, which often just doesn't quite reach enough I have used all of the listed lenses. There are others with good reputations but I haven't used them so cannot credibly recommend them. If only more posters adopted that attitude! [SNIP] The Pentax LX is a superb working tool, one that was never adequately marketed so it didn't sell so well against such cameras as the Nikon F3. Beware the deterioration of the mirror bumper foam and felt light traps that signals the need for a thorough service, including the replacement of several rubber components in the mirror system which, when perished, give incorrect infinity focus. This service can be carried out by Pentax UK, although many UK Pentax enthusiasts go to Asahi Photo in London, who do an excellent job for under £100, which will last for about 15 years until it needs doing again. Pentax UK claims that they use new materials when they replace the foam and rubber compononents, and the newer ones should have a much longer life. I don't know that anyone has had them long enough to find out for sure yet, of course... Nice to know that they claim that. I used to use a very good electronic organiser called a 'psion' - they were excellent in every way, except that the screen cable broke every 1-2 years, and cost £70 to replace. psion knew it was a fault, but I think they quite liked the business it generated (they went out of business, though, I would say it serves them right, but now there isn't a replacement). I like the 'look' I get with Pentax glass better than any other 35mm system that I've used, but this is a very personal thing. It seems to me more of a close match to the look I get with my Schneider lenses for medium and large format than other 35mm manufacturers, and is often said to be the most 'German' looking of all the Japanese makers, with which I would agree. I might marginally prefer Leica for black and white, but it is marginal: for colour Pentax remains my favourite. And the SMC coating is unbeaten. Peter Ahh Pentax, so undervalued! (Like me really...)

"Bandicoot" wrote in message ... "Duncan J Murray" wrote in message ... "Bandicoot" wrote in message ... "Duncan J Murray" wrote in message ... Any opinions? Why is the LX praised as being a modern classic, when it seems technically inferior to the OM4? Duncan. I suppose the flippant answer would be that most LXs ever made still work... And the OM4? Do they break down a lot? That would be a definite negative for me... Well... The LX has a reputation for going on forever, though you need to have the mirror buffers, damping foam, etc. replaced. The OMs used to be teased by many pro.s as feeling too fragile, and I know they never had the reliability of the Nikon Fs that most such users carried - but then few things other than bricks have the build of a Nikon F or a Pentax LX, so I wouldn't necessarily let that worry you. I was deliberately being flippant by reviving an old joke. People seem to think that just because things are small means they aren't well-made and reliable (though fragile, I concede). People think for things to be well-made, they need a Nikon F ; I mean, what torture do they put their camera through? No one would say a genuine swiss watch was not well-made, but then no-one would go rock-climbing with one either and expect to keep time afterwards! Then again, the romantic idea of travelling to far-off parts of the world, with your trusty camera recording the extreme and untouched lands you encountered does have a certain appeal. I think I would take a Pentax MX or a Nikon F (couldn't afford a Leica) (actually couldn't afford a Nikon F just at the moment, anyway, let alone a round-the-world trip!!! - we can all dream!) If you intend to work a lot in the field miles from repair facilities, in adverse conditions, and depend on your camera for your income, maybe you wouldn't use an OM - but then in that situation whatever you used you'd be carring a couple of spares. In a more benign environment I wouldn't feel worried: I'd trust the 'toughness' of an old OM more than many modern cameras. Definetely. I think the OM series showed that good quality could be made into a small body (that is small for SLR of course - there was leica). But more seriously, I think if you handle one, you'll know the answer. And while I much prefer the LX, the OM4Ti should surely be counted as something of a classic too, though more for its electronics than anything else - this isn't a case of "there can only be one". I've handled both the LX and the OM4 (not Ti), and found the OM4 to be extremely competent, particularly regarding the funky lcd metering, which seems to be precise to 1/3 stop, and very comprehensive with exposure lock and spot metering. I think it is more on the gadgety side, especially re the highlight and shadow buttons which are totally unecessary, and are not adjustable for different film. Some people love those highlight and shadow meter options, but I probably wouldn't see much use for them - if I'm using a spot meter (which I do, a separate one, a lot) I'd rather make my own decisions about how far to bias the exposure up or down from the highlight, shadow, or whatever else I choose to meter on. They go +2 and -2, which I suppose is sensible, but totally depends on the film, and might be a bit too far for Fuji Sensia, and no where near correct for negative colour, let alone black and white! When I have to use an in camera meter, I love the LX's very _predictable_ meter, and can cheerily decide how to adjust my exposure around the meter reading. It is superb for long exposures too. I suppose that the LX has a much more professional feel to it, with the safe exposure compensation and sturdy parts. I like the way it handles, and it does feel very 'solid' to me. I also make a reasonable amount of use of the interchangeable viewfinders. The dust sealing really works too. I have five of them - 'nuff said... Do you find exposure compensation a bit unwieldy? I nearly dropped the camera when looking at it...! What about the optics? How does Olympus glass compare to Pentax glass around this era? I've answered this below, by adding my own comments to Tony's post on this subject. Basically, there are some great Zuiko lenses, but the Pentax line has a more consistently high quality - and personally I really like the 'look' I get with Pentax glass. Thanks for you reply Duncan. |

Charles Kinghorn Ahhhh... But didn't you know that the Pentax loupe is biased for photos taken with Pentax??!!!! Thank you for your post - I presume you stayed with Pentax for your architechural work? Duncan. |

... "Duncan J Murray" wrote: There are some very good Zuiko OM lenses, notably the wide aperture fixed focal lengths and the most recent MC lenses. There are some very poor ones too. The zooms were disappointing by the standards of the 1970s and 1980s, and even more so by today's standards. A friend of mine had a 50mm f1.8, which, from the small prints she got, seemed extremely good, in terms of colour and contrast etc... So wondered about the other lenses. The 50mm f/1.8 is the sharpest lens in the Olympus OM system, and its performance bears comparison with the best 50mm f/1.7-f/1.8 lenses from other manufacturers. It was an immensely popular lens. Just try to find one without fungus and cleaning marks! That ties in with my friend's experience. I have a 35-70mm SMC-A f3.5-4.5, which I've found to have excellent colour, contrast and resolution. I recently enlarged a photo taken at f8 at night on fuji sensia 100 (or was it reala?) to 30x20", and the level of detail was astonishing (good, that is). Currently, being a poor student, this is the only lens I have, though I am looking to a 50mm f1.7/f1.4 for my next acquisition. The 35-70mm A is a great performer. I have one that came with an MX body I bought as a spare. By today's standards, the zoom range is limited, but it is optically very good. Nikon made a comparable 35-70mm f/3.3-4.5 AIS, which was one of my favourite Nikkors. Unfortunately Nikon allowed Cosina to use the Nikkor branding on a cheap 35-70mm f/3.5-4.8 for the Nikon FE10/FM10, and that was a dog by any standards. The 35-70mm is great in terms of outright resolution (though not sharpness - depends on your taste), colour and contrast. However, this isn't comparing it to anything - just it's sort of absolute qualities. However, it's achilles heel is distortion at the extremes (ok, at 35 and 70) - which you need to watch out for. Personally, I don't mind, but it rules out some shots, and if you're into Georgian architecture in a big way, I don't recommend it! Some of the "star performers" of the Pentax range actually have a star to let you know which they are, including an outstanding SMC PENTAX-A* 85mm f/1.4 and a 300mm. They tend to sell for big money, but there are other gems too, at lower prices, notably: Ha ha! Logarithmically totally out of my price range! But I've heard that they are something special. (the 43mm lens looks very nice...) The 43mm is a "Limited Edition" autofocus FA* lens, but it looks more like a manual focus lens. There are also 31mm and 77mm "Limited Edition" lenses. I have tried them all and don't particularly like them, because the designers have given the sharpness at the expense of bokeh. The 77mm is not too bad, but it just cannot compete with the superlative 85mm f/1.4 A* for bokeh. Interesting... I liked the idea of a 'ghostless coating'. Makes it sound ethereal. Also, looking at the sharpness over the diameter of the image is interesting - it's a smooth MTF curve, not often seen. I wondered if the focal plane was spherical rather than rectilinear. 24mm f/3.5 K, 28mm f/2.8 A, 35mm f/2 K and A, 50mm f/1.4 K and A, 50mm f/1.7 M and A, 50mm f/2.0 K, M and A, 105mm f/2.8 M, 200mm f/4 K, M and A. In zooms, I would strongly recommend the 35-105mm f/3.5 A, which offers very good sharpness, low distortion and excellent bokeh. The 70-210mm f/4 A is good but not outstanding. There is also a 28-70mm f/4 autofocus lens that is optically outstanding but costs very little. A goldmine of information... many thanks. Although do you really think the 50mm f2.0 is any good? It's just that I've actually got one, and havn't used it since I got disappointing results from a trip to South Africa. I think it had the resolution, but the colour was a bit bland and non-contrasty. However, there are loads of other factors, like it being in rubbish condition, having no UV filter, and I can't remember the processing. I have a 50mm f/2 and it is just fine. The best of the 50mm lenses is probably the f/1.7, although the f/1.4 K runs it pretty close and the f/1.4 A beats the equivalent Leica M optic for its sublime combination of sharpness and bokeh. Interesting that you find the f1.7 better than the f1.4 - I think I'll save myself £40 and go for the f1.7 (yes shock, horror, I don't have a standard prime!). I'm eyeing the 24mm and 28mm.... The 28mm f/2.8 A is the best of these, with the 28mm f/3.5 K not far behind. Avoid the M. Used Pentax lenses are easy to find (try eBay) and cost very little money for such excellent optical quality. You will pay much more for the few Zuikos that are optically their equals. Good point. Looks like I'm tending towards Pentax here. If you really like the OM4Ti, and have money to spend, I can put you in touch with a used camera specialist who regularly offers the best of the Zuikos in excellent to mint condition. But the prices are several times what you would pay for Pentax lenses on eBay. Thankyou, but I get the feeling I'm going to stick with Pentax. It was always a factor that I am much more used to shutter speeds being near the shutter release, and aperture control being near the aperture. Hmmm... The LX sounds a great camera, apart from this sticky mirror problem. If I were to spend 200+ on an LX and then another 100 for servicing I think I'd be a touch disapointed. But if it last 15 years, then I suppose it might be worth it. I did exactly that; I bought an LX with a sticky mirror and had it serviced. It has had a lot of hard use and is 100% reliable. Isn't a hand held meter big, clunky, expensive and awkard to use? Yes, but it is the best practical way of measuring incident, rather than reflected light. If you are using slides, or digital, the combination of an incident meter and reflected light spot meter in one casing makes for a very versatile tool. I have an excellent case (lowepro TLZ 1, FYI) which conveniently fits my Super A, zoom lens, flash gun and tripod all in one. It could fit a spot meter, too... but not sure what the point of that would be with the Super-A, where I don't know if the shutter speeds bear any relation to SI unit seconds, and the zoom changes aperture as you zoom.... hmmm. Do you anything about the 50mm f1.8? I think that would be what I'd start with if I were to go for an OM4 in the future. See my comments near the top of this reply. There are a lot of worn and neglected Zuiko 50mm f/1.8 lenses available. They seem especially prone to fungus. If you manage to find a good one, they are an excellent buy. I currently have a Pentax Super-A, and the X-700 doesn't look too dissimilar. I don't have any problems with the Super-A, apart from it would be nice to have a camera that feels more solid and with 100% viewfinder coverage (or near there). The Super-A is super solid. I have two, both of which I bought in near mint condition. One is kept in reserve, the other has had a lot of use but still keeps going. I have a shutter tester which checks manual shutter speeds and auto exposure, and the Super-A is spot on. Great camera. I kind of preferred my Program-A as it had a corrugated mode selection switch (these little things make such a big difference), which means it could be switched onto 'auto' long before I consciously considered taking a picture. However, the achilles heel of the Program-A forced me to move to the Super-A. First manual mode disappeared - leaving me with only auto and +/-2 stops exposure! Er... then Program mode went, leaving only aperture priority (no big deal, except convenience with flash gun), then half of the apertures on the stopped-down side went the way of program mode (22-11) - more a problem! However, it was around this time I took one of my favourite pictures, which I entered for SI symmetry shoot-in earlier. Then it started underexposing by 4 stops every other photo, and I decided to put an end to it all. It currently retires on my shelf. The Super-A is, indeed, Super. Manual mode works, which is a godsend for me, and it's much more solidly built. It looks good too, though unfortunately this is also a problem : it looks so good people keep mistaking it for a digital camera (that is non-photographers of course), and it attracts too much attention for candid photography. I've seen a Canon QL-24 going for £20, which would be perfect for candids. Actually, that's just reminded me of an amusing article I read in 'digital photographer' magazine (an interesting high quality magazine would good content, quality paper and printing, but flagrant disregard for 300dpi and spelling) issue 26 - where they interviewed Nick Danziger about his really excellent shots of Tony Blair and other polititians (they really are absolutely fantastic photos - unposed, too). Then they had a little section on equipment recommended for doing this type of shooting, including Canon EOS 1D mark II with a huge 16-35mm f2.8 lens. I thought (and you will too if you look at the photos), that's a bit odd - they're all in black and white, and people don't seem to even notice the camera - surely it's not a 1D?! Then you look at the other section which shows his actual equipment - a battered OM4ti with Neopan. The Nikon FM3A is a very fine camera, and can be obtained new for only slightly more than the cost of a good used OM4Ti. There is a massive choice of Nikon glass, and used manual focus Nikkors represent incredible value because they don't meter on many Nikon AF cameras, so they get sold on eBay at low prices. Yes, the FM3A seems a very nice camera, at a reasonable price. However, I was surprised to find it didn't have a 100% viewfinder (I thought most top Nikon's did). And what you say about he glass is very enticing... Particularly as they are Nikon lenses. The FM, FE, FM2, FE2 and FM3A all have less-than-100% viewfinders. The only Nikon film bodies with 100% viewfinders are the F, F2, F3, F4, F5 and F6. What's so hard about making 100% viewfinders? Surely, just a few more percent...and we'd all be happy...?! However, finding Nikon lenses with both good sharpness *and* the "look" is not easy. Try the 24mm f/2.8, the 105mm f/2.5 and the 180mm f/2.8 in AI or AIS versions. They are very good. But there isn't any 35mm Nikkor (out of the many different versions) that remotely compares to the SMC Pentax K or A 35mm f/2. That is surprising. Not surprising when you think of Nikon's target market, professional shooters, particularly photojournalists. Any finely graded rendition of tones and smooth rendition of out-of-focus highlights is instantly lost when you use an 85- or 133-line screen of the kind that was used in newspaper reprographics departments. Nikon lenses are optimised for sharpness and contrast, which is what newspaper picture editors wish to see. Makes sense in theory, I suppose. Lens design is fascinating. I'd love to know what makes a lens sharp, as opposed to just being high resolution. Maybe something to do with 'unsharp masking', whatever technique that was (I presume optical). Then there's saturation, colour, contrast, resolution, bokeh, drawing etc. etc. etc. You'd need to be some kind of god to understand it all! Do you know of any manual cameras with 100% or near to that viewfinder coverage. My Super-A has 92%, which can be slightly annoying. The LX has an excellent 98%, FM3a 93%, Olympus OM4 97%, X-700 92%. All the Nikon F{single digit} cameras have 100%, plus I think (not sure) the Canon EOS 1, 1N and 1V have it. The Pentax MX has 95%. That's another body worth considering; manual focus, manual exposure, but it has interchangeable focusing screens and is exceptionally robust. get a good one and it will last forever, or until the electronics go phut! - but the shutter is purely mechanical so you only lose metering. My favourite Pentax outfit was LX + MX (or Super A) and five or six lenses. Yes, Pentax MX is really really good camera - I think it could be the ultimate travel camera - small, well-built, doesn't need batteries, great lenses, inconspicuous. What more could you want?

Yes, these will all also focus to infinity, and yes they can be used as 'normal' lenses. Two things make a lens a 'macro' lens (not counting all those zooms with so-called macro functions that are nothing of the sort): it has a focusing mount that lets you get close enough to get a life size image on the film (strict definition, but half life size just about gets away with still calling itself a 'proper' macro); and the optics have been optimised to perform well at close distances (most lenses perform less well as you focus close) and to have flat field, so that if you use it to photograph something flat - to copy a map, say, wide open it will be in focus in the corners at the same time as in the centre. The focusing mount thing makes the lens bigger and heavier, but doesn't affect its distance performance at all. The optical optimisation could in theory, but in practice not: these tend to be the sharpest lenses in any manufacturer's arsenal, and so their distance performance is at least as good as that of a non-macro lens. Downsides to using a macro for general photography: bigger, heavier, and more expensive; almost always a stop or so slower than a non-macro of equivalent focal length; often, but not always, has less attractive bokeh than non-macro lenses. Exceptions to the latter are the Tamron 90mm, and the Pentax macros, all of which seem to have very nice bokeh. (Personally, I think good bokeh matters as much, if not more, in close work, so this is a big Pentax plus for me.) I have a number of Pentax zoom lenses, mostly newer ones, and can vouch strongly for the 28-70mm f4 FA AL - it is more or less the optical equal of the f2.8, but at a fraction of the cost, size, and weight. The current 24-90mm is very good too. I don't have a Pentax zoom in the 80- 200 range, so can't comment here (I use an Angenieux 70-210 instead, and find it fits well with the 'look' of the Pentax glass.) Oh, well, I do have the 80-320, and it is good for the price and the range, but I only use it when I _really_ need to cover all that range in a single lens, which is not often. 24-90 seems a very nice lens. Very useful focal length range - 24mm is great for landscape, and 90mm for portraits! I have a 35-70, which often just doesn't quite reach enough Yes, it's an excellent range, and would probably be the lens I'd choose if I was forced to only use one - though I'd hate to have such a choice forced on me. It isn't cheap, but is very sharp, and is light for its range. The 20-35mm f4 is a good lens too, and makes a very nice companion to either the 24-90 or a 28-70. (There are good Pentax choices in the 28-105 range too.) [SNIP] Ahh Pentax, so undervalued! (Like me really...) LOL! Me too... Peter |

[SNIP] People seem to think that just because things are small means they aren't well-made and reliable (though fragile, I concede). People think for things to be well-made, they need a Nikon F ; I mean, what torture do they put their camera through? No one would say a genuine swiss watch was not well-made, but then no-one would go rock-climbing with one either and expect to keep time afterwards! Then again, the romantic idea of travelling to far-off parts of the world, with your trusty camera recording the extreme and untouched lands you encountered does have a certain appeal. I think I would take a Pentax MX or a Nikon F (couldn't afford a Leica) (actually couldn't afford a Nikon F just at the moment, anyway, let alone a round-the-world trip!!! - we can all dream!) I like the MX very much - have two of them - and it is an excellent alternative/backup/lightweight second body with an LX. I do use more recent 35mm SLRs too for the few things that really call for AF, and there a Pentax MZ-S is backed up my an MZ-3, which is another very light machine. The MZ-S is very light beside a Nikon, of course, yet the time I accidentally banged it against the corner of my house, it knocked out a chunk of brick from the house while the camera was _literally_ un-marked. [SNIP] When I have to use an in camera meter, I love the LX's very _predictable_ meter, and can cheerily decide how to adjust my exposure around the meter reading. It is superb for long exposures too. I suppose that the LX has a much more professional feel to it, with the safe exposure compensation and sturdy parts. I like the way it handles, and it does feel very 'solid' to me. I also make a reasonable amount of use of the interchangeable viewfinders. The dust sealing really works too. I have five of them - 'nuff said... Do you find exposure compensation a bit unwieldy? I nearly dropped the camera when looking at it...! It has always seemed fine to me, but I suppose I've had quite a while to get used to it. Also, I'm not working fast and constantly changing the compensation: mostly I use manual and a spotmeter, but if I am using auto and the compenssation I will tend to work out what compensation I need for a shot or sequence of shots and set it once, then change it only when I am readying the next sequence. I do like the really big flag in the VF that tells you that compensation is applied. Like any camera, you get used to working with it, and your own working methods evolve in parallel with the way you use it, I suppose. Peter |

oups.com... Most lenses are pretty good at f/8. the real test is near maximun aperture. that's where the Leica lenses would trounce the Pentax optics. Apart from this being hilarious in itself, your use of the word 'would' is so enlightening. It's a plain statement that you haven't tried the experiemnt, and aren't prepared to do so. What a surprise. Peter |
