Help me out here with this IS thing. For a long time I just ignored the whole discussion. I either lived with primes: the 300mm f/4.0, the 400mm f/5.6, the incomparable 135mm f/2.0, and the old “holy trinity” 16-35mm, 24-70mm, and 70-200 each f/2.8 - all used, all older. Couldn’t afford anything “better.” So I didn’t get what IS was for.
I finally - due to increased skill and starting to get paid better for my work - bought the 70-200mm f/2.8L IS v.II, one of the finest lens yet made. Since it was/is used mostly for action, sports, animals, birds, etc., I just left the IS off because in my experiments I couldn’t see any benefit.
Then I got tired of carrying the 300 and the 400, and by golly this fancy, all shinny, all dancing, increase your sex appeal 100-400mm f/4.5-f/5.6L IS v.11 with three (count em), 3 IS modes. “3 stops of improvement!”
I know this is heretical and I’ll get fried at the stake, but I’m just not seeing any thing amazing here. Say I’m using the 100-400 at IS0 6400, f/5.6, 1/60? Did I get 2 stops of “improvement?” What got better? I’d have loved even a half click of Tv, a half stop of f for greater FOV. Are you saying I already got those improvements even though I can’t see it?
So once again IS --> 2 stop =
