I keep reading about IS in modern cameras and lenses and people seem to go on about it as if it's essential. It's not in any camera I have and it was never in any camera I've ever had. I've managed to get perfectly good and sharp shots over the years, hand-held with 450mm lenses. The rule of thumb was that to avoid lens movement ruining a shot you the shutter speed in fractions of a second must be at least the length of lens used. So, if you're shooting wide open in low light with a 50mm lens you can get away with 1/60th sec. But if you're shooting on a sunny day, but in the woods, with a 450mm you need 1/500 sec. You know there is a risk of shake so you're careful, if you can use a tripod you do, if not then a monopod, or a bean bag, or rest the lens on a branch, or lean against a tree. With a little care you can get that speed down without needing a tripod. Just what is the big deal with IS? Have I missed the point? Weren't most of the best photo's in the world shot without it? I'm not looking to start a flame war and this is not a troll. -- Justin C, by the sea. A very good professional nature photographer once remarked that, before IS, he was lucky to get one good shot per roll of birds in flight. With IS, the ratio has now improved to almost all of the shots. Most of my shots are of more stationary target so I would not expect such a dramatic improvement in my photography. This sounds like just the opposite... If you have a stationary target, IS will let you slow down the shutter and still hand hold. The movement you are compensating for is you. No. Not in this particular case...because he's referring to PANNING. *NOT* the still-holding of teh camera, but PANNING...which IS is extremely helpful in. But if you have a fast moving target and need to freeze action, you still have to shoot the higher shutter speed, IS or not, and so are already fast enough to hand hold. The movement you need to compensate for is the subject. Only if he's holding still as the bird flies through his shot...which is rarely how you'd capture a bird in flight. Try it sometime. This is a panning issue, which IS has a huge positive effect on. -MarkČ -- Images (Plus Snaps & Grabs) by MarkČ at: www.pbase.com/markuson |

Weren't most of the best photo's in the world shot without it? I used to submit my advertising in four film negatives, one each for C, M, Y, and K. The process of creating the advertisement in a suitable form to generate those film negatives was equally cumbersome. I now design, layout, and proof my advertising on my monitor, then generate a high-quality PDF that is either emailed or uploaded to the printer. I had great results from the old film negs, and I get great results now from PDF. The difference is, I now get more "consistent" results. I have cameras and lenses without IS, cameras and lenses with it. As a rank amateur, I wish that EVERY piece of equipment had IS. And the first time I experienced it, it was a marvel to me. Image stabilization is another tool in your camera bag, one which helps you get more out of less. Why would you NOT want it? The answer to that is a simple one, IMO. =Lack of experience with IS, which is *precisely* what the OP indicates as his history. That kind of criticism is understandable (and IMO *only* understandable) when one hasn't seen it first hand. IS isn't a miracle, but it is arguably the biggest step in lens technology in at LEAST the last10 years, or perhaps even more (pre-dating it's existence, which started in about '96 or so). -- Images (Plus Snaps & Grabs) by MarkČ at: www.pbase.com/markuson |

This is why I like it.

Now wouldn't you rather have a faster lens? |

Until an innovation has actually been introduced and put in service, _all_ the "best photos in the world" (and the average ones and the really bad ones as well) were shot without it. The question is not whether one can take good photos without it, the question is whether one can take _more_ good ones _with_ it, or take the same good ones one was going to take anyway with greater convenience. At one time most of the best photos had been taken without a dry, storable emulsion, color film, a shutter, a viewfinder, a hand-holdable camera, etc. If what had been used to take "most of the best photos" was the criterion for acceptance of an innovation we'd still be preoparing emulsions on site with cameras that took two men and a boy to carry and required exposures so long that the movement of rocks was an issue. Is it "essential"? In the sense that one will die if one lacks it, no it is not "essential"--neither is a camera for that matter unless it is your means of livelhood. Does it make life a whole lot easier sometimes? Yes, it does. I'm not looking to start a flame war and this is not a troll.

I'd like to see some solid tripod vs. IS comparisons, though. I did this with the tests I described below, after noticing that sometimes at higher shutter speeds the images got worse, which I tracked down to shooting at the smallest apertures as the shutter got faster. (So after this I limited the apertures to the 'sweet spot' range by changing the ISO values as I shot at different shutter speeds). (The problem with that, though, is that most people don't own a tripod capable of holding a 300mm lens adequately still for 1/100 second.) Any decent tripod can do this (if there is no wind or external vibration) if you use MLU with a 10 second delay and use an electronic shutter release (instead of pushing the shutter button with your finger). I found the 2 sec delay wasn't enough (still getting some vibrations from the mirror slap) but 6 sec was plenty with the lenses I used, up to 500 mm and 1/20th sec). Bill |

Sure they were -- it's a recent technology, and fine photos have been building up for years. You can say the same thing about fast lenses (who really *needs* a 400 f/2.8? Can't you just use faster film?), long lenses (what's the point of a 600mm lens? Why not just get closer?), fast films (just use ASA 100 and expose longer; and you'll get finer grain to boot!), and so forth. IS gives you more options in some situations. Hand-holding with IS is easier to make quick adjustments to than solid mounting on a tripod, so you can adapt to subject movement and and get photos that you'd mostly miss using solider mounting techniques. Whether it would result in significantly better pictures for your particular work, I can't say at least twice; I don't know your work, and *I've* never owned an IS lens either. |
