EOS 40D vs. 50D
This is an update to my earlier post.
I've received most of my new camera outfit (still waiting for a few filters, a new bag, and LCD protectors). Contrary to my earlier post, I opted for the EOS 40D (though I did get the 100-400mm L-series lens - it's huge!)
There were multiple reasons for this. First, the review of the 50D at dpreview.com indicated that it actually did worse in terms of noise at high ISO settings than the 40D. Another reason was that the 50D, with the lens I would have chosen, was at least $700 more than the 40D.
A third factor was that, when shooting multiple frames at high speed, the 40D is actually quicker (6.5 frames/sec) than the 50D (5 FPS).
Given that my primary subjects are critters, and that I'm not blowing up my pictures to wall size or doing professional model shoots, I concluded that I really didn't need the extra pixels and the 50D was not, at this time, worth the extra cost for me. I may buy one later down the road, as a spare body, but the 40's going to be plenty to handle for now.
Just some things to consider if you also happen to be shopping for a "prosumer" DSLR.
Happy shutterbugging.
