| I can't speak about canon, but can offer one or two pointers about olympus. Please don't get me wrong here, I have never used one, BUT that does not invalidate my comments.
The olympus cameras are 4/3 system, which is OK if you a) like the format, and b) shoot mostly telephoto, because the crop factor is 50% not 66% like it is for pentax and low cost cannon DSLRs. BUT, the crop factor of 4/3 cameras is a problem at wide angle. a 7-14mm zoom (equal to my sigma 10-20mm) costs about $1500. with that, I can buy a K10D, the sigma 10-20, and perhaps a good flash.
As a result, economically, if you want to go wide angle, smaller is not better. go for a body with ASP-C sensor, not 4/3. also the larger ASP-C sensor, for any given pixle count, should be better at every ISO with respect to noise, just because each pixle is bigger. bigger pixles = better noise performance, that is part of th einterest in Full Frame cameras.
Also, the cameras are small, some people like that, but I find that when you take a small body, and then hang 1-2kilos of 70-200f2.8 plus a TC, it is hard to hold. I have an *istD and K10D, and actually prefer the larger K10D just for that reason. |
