It's quite difficult to properly test image stabilization. that goes for you too, which means you haven't tested it either, so your claims are also anecdotal and opinion.

Uh, no. IS claims to "fix" up to "n" stops of shake. That's the _exactly the same_ excursion for every lens, whatever the focal length. If you can hold your lenses steady enough for 1/<focal length> shutter speeds, then for an 800mm lens, image motion at the focal plane at 1/100 is exactly the same as image motion at the focal plane for a 200mm lens at 1/25. Longer lenses require a faster response time, though. FWIW, I read about someone who tested a cheap supertele with stacked TCs on one of the first in-camera IS systems. It worked fine even with insanely long focal lengths. -- David J. Littleboy Tokyo, Japan

That's the _exactly the > same_ excursion for every lens, whatever the focal length. as the focal length gets longer, the same amount of shake causes a much larger movement. that's why you need a faster shutter speed to 'freeze' it.

I hate to break it do you, but it's still not going to improve your photography. You can count on that, all the way to their banks. |
