This, That, or The Other
I am thinking of purchasing a high grade camera lens in the $800 range and keeping the camera. I'm still using two of the lenses the camera came with when I purchased it. They are good lenses, but are not professional grade. I'm considering the Zuiko Digital ED 11-22mm F2.8-3.5 lens which might be a good purchase because I think the camera is still a good one, even though it went out of production several years ago.
On the other hand, I have considered purchasing a new Olympus DSLR professional grade camera: The E-3 which seems to be the workhorse of many professional photographers who also use Olympus cameras, is the one that makes the most sense at this point. The only problem I see is that the E-3's resolution is only 10.1mp which is the same as I get with the E-510. A newer model is coming out, but it may take another 2 years before it hits the market.
A third option I'm considering is ditching the Olympus brand altogether and going with the Canon EOS Rebel T2i. The resolution seems to be a lot better than the Olympus brands (18mp), and a lot of professionals seem to like using this camera.
What would be the best and most economical way to upgrade? I'm unfamiliar with Canon cameras and don't know any of the pitfalls of that brand. Any advice would be helpful. Thanks
