do i need the IS? well i'm not really sure...i was just going to get it just for the fact that it seems like it can be quite useful in some shooting instances, but i guess i'm not completely sure whether or not i do. any suggestions on how i would know??
Generally, if you're shooting subjects that are moving constantly [Wherein you NEED the fast shutter speed] or shooting from a tripod/monopod constantly, I'd say forget the IS
If however, you're shooting in low light, with some static/slow moving subjects [Where shutter speed is less important] or you do a combination, get IS
If I had the money, I'd probubly get the 2.8 IS, Sharpness does nothing if you cant get the shutter speed you need...and this is coming from someone thinking of saving for the 70-200 f/4L IS because he shoots his 200 prime at f/4 or 5.6 [or slower] 90% of the time because of depth of field...and because his subjects generally are stationary or not moving..and of course saving money as well!
But thats because I have the 200 f/2.8L prime, when I NEED the speed, I still have it....Unless i sacrifice it to get a Sigma 150mm f/2.8 or 180mm f/3.5 Macro or something [Given the shooting I do with it most, the Macro would possibly be of use to me more than the 200 prime at that point]
That said i change my mind weekly ;D
