Canon FD to EOS adapter?
I read or imagined reading about a new product for using Canon FD lenses on the
newer EOS cameras. Did I imagine this? Or does someone else remember reading it or seeing it and where? David Frantz |

David Frantz Since the lens communicates with the body in the EOS, I should think that such an adapter would by its very nature be either very limited in its functions, or cost more than a new lens. I have seen odd adapters years ago offering lens to body exchange, but they were also limited in metering abilities. And aren't the FD lens the ones that utilize the breach lock? Sounds like a wistful imagination IMHO. |

I don't know of a new product, but there were some in the 1980's. Because of the smaller register distance of the EOS, all either used optics or lost infinity focus, and lost all automatic.

There are "two types" of adapters. One is a "cheap adapter" (made by a
number of "manufacturers") where you will lose "infinity focus", the other is a very expensive one that only Canon produced and you don't lose "inifinity focus" but it only works with mostly "L" series lens (which are typically very expensive).

I'm not sure that I trust it, but I may try it when I get a digital body. I currently shoot with teh T90, and I have some really nice lenses for the FD mount. It would take me years to afford the same lenses in autofocus. It would be nice to continue using some of my best FD lenses will saving up the money to replace them.

In terms of the difference and the possibility of working with a digital
camera, it is there. Basically, the cheaper variety (in general again), are just mechanical couplers that allow the lens to fit a body. What they do is introduce space thus changing the focal distance. Digital cameras do this with "normal lens" without the adapter (ie. the focal distance is changed) because of how the camera and pickup are built. Thus, I "mis-stated" a bit... sorry, I should have read your comment more closely. However, for film body cameras, you will need the expensive adapter to use some FD lens on an EOS film body camera. The expensive adapter has optics in it to "adjusted" the focal distance. There is one cheaper model (third party) but from comments else where it does not result in a very good picture because of other "optical issues". As for working with all lens on a digital body, I would think this is probably OK as it is a mechanical adapter. The reason for the "restriction" on the expensive canon adapter is that the lens element ( I think) in the adapter get in the way of the rear of most non-"L" series lens... if I remember the discussions in the past. Hope that helps a bit more. "Meghan Noecker" wrote in message ... On Wed, 05 May 2004 13:59:22 GMT, "Budwich" wrote: There are "two types" of adapters.

This is what I have read on the canon sites. The guy selling on ebay has several, and I suspect they are the cheap kind. But when I asked him, he insists that they do not lose infinity, and he is promoting them for use with digital cameras. I specifically asked him about the infinity focus and also if it needed a different focusing screen. Also, if it worked with all lenses as I believe they only work with lenses that have the recessed rear lens. I was not confident with his answers, but I may enquire again once I have a digital SLR body. I would love to be able to shoot wildlife with a digital camera, and I have a wonderful 150-500mm/ f/5.6 that is great for that. But I cannot afford the autofocus version.

I owned both Canon adapters at one time.
The glassless version acts like an extension tube so most lenses loose infinity focus. This would be the adapter to use for wide-angle lenses, as DOF might still get acceptable focus for infinity. The other version has one or more lens elements built into it. This allows the lens to maintain infinity focus. However, the adapter now acts like a tele converter (I think it's something like 1.1x or 1.2x). This also means that some lens speed is lost (as with any tele converter). I'm thinking Canon recommended it for use with telephoto lenses only, because they may have corrected for longer focal lengths. There is no protruding element in the adapter to prevent use on wide-angle lenses, but performance would suffer. Neither adapter fulfilled its promise, and usefulness turned out to be rather limited. The main problem lies in the lack of autofocus for the lens, conbined with the lack of focusing aids on the focusing screen (at least for the Rebel and Elan families of Canon bodies and for the entry level Canon DSLRs). If your FD lens is not 2.8 or faster, the focusing screen would be more or less dim as well. We are also talking manual aperture, so the lens must be stopped down manually prior to taking the photograph, and then opened again for focusing the next photograph. Also, since those adapters aren't exactly cheap, unless you have really expensive FD glass, it would make more sense to sell your FD equipment, save the money you would have spent on the adapter, and get yourself some EF gear for it. Here are some "great value for money" EOS lenses: lens used new EF 15 2.8 Fisheye $370-$420 EF 20 2.8USM $275-$350 $400-$450 EF 24 2.8 $170-$225 $270-$280?

What I will do is buy a digital body and then one lens at a time. Unfortunately, It will be a long time before I can replace my best lenses. My 85mm f/1.2 lens is about $1200 used in the autofocus version. So, I have to stick with manual focus to use that lens. While there is a EF version of the 85mm/1.2 available, it is not as good optically and with slower AF than the 85mm/1.8, which is one of the lenses recommended earlier. BTW, the 85mm/1.8 and the 100mm/2.0 are among the sharpest lenses Canon has to offer, the 50/1.4 falls into the same category. Also, I love going to a nearby wildlife park, but I usually spent $50-100 each time on film and processing. I have a great 150-500mm f/5.6 lens. I've also got a nice 400mm f/5.6 that I can easily handhold while on the tram ride. And I also have a nice 80-200mm f/2.8 lens. All of these have the recessed rear lens allowing use of the 1.4x teleconverter. These 4 lenses are the mainstay of my business. Yet they are all pretty spendy, 2-3 times the cost of the manual focus lenses, and that's used. It sounds like you are not going to spend $4k to $8k to get a Canon 1Ds or 1D mkII, so if you want to do Canon DSLR, you are talking either a 10D, 300D, or a used D60 or D30. All of these bodies have a cropping factor of 1.6, so you'll only need 300mm of focal length to approximate the same angle of view of the 500mm on your FD system. I would say you have plenty of options even if you're on a budget. 200mm/2.8 (equivalent 320mm FOV) 200mm/2.8 * 1.4 gets you 280mm/4.0 (equivalent 450mm FOV) 200mm/2.8 * 2.0 gets you 400mm/5.6 (equivalent 640mm FOV) The 200 2.8L sells for $635 at B&H, and combined with the 1.4x ($280) and 2x ($280) it would exceed the capabilities in speed and long focal length of your current 150-500 lens, it would also get you a decent 450mm FOV at f/4 which is one stop faster than your current 400/5.6. It does not quite get to 700mm (150-500mm with 1.4x), but almost, and it is a stop faster. So this $1200 set might replace the 150-500mm and the 400mm lenses, assuming that your use the long end of your 150-500mm more than the short end (you have the faster 80-200 for the 150mm range). Alternatively, you could look at the 70-200/4L ($550) plus 1.4x to cover 115-450mm FOV (115-320mm FOV at f/4 and 320-450mm FOV at f/5.6). This would set you back $830, but it won't quite cover the same range as your 150-500mm. The 80-200mm 2.8 would be more difficult to replace (there is no 50-125mm 2.8 in Canon's lens lineup which would replace your lens). One approach would be to get a 50mm 1.8 ($75) or 1.4 ($295) combined with a 85/1.8 ($325) or 100mm/2 ($370) or 100mm/2.8 macro ($450). The only not-so-expensive, but still usable zoom lens that would could that range is the 28-135/3.5-5.6 IS lens ($394), but it is way slower that what you are used to, although it offers image stabilization. I suggest you calculate how much your FD glass will sell for, add $100 (for the FD to EOS adapter), and I'm thinking it would be very close to paying for the EF lenses suggested above (e.g. 50/1.8, 85/1.8, 70-200/4, 1.4x for $1230 new).
