I've been a Canon DSLR shooter for a few years, and I've always loved the 40D. Bought an E-M5 about two months ago, and probably have not touched the 40D for six weeks. For some reason I pulled it out of the bag tonight and took some throw away shots in my dimly lit office. Wow. A camera that I felt was ergonmically almost perfect feels like a big black rock in my hands. Shocked. Snap a shot. Shocked again. That shutter crash sounds almost violent in the quiet night. But it focuses fast and takes sharp pics, with the modest 50/1.8 attached. So I grabbed my E-M5 to do some modeling duty. Shoot a few in M; a few in A. Not bad, but not great either. Between the slowish shutter speed and trying to expose for the black subject properly I am not getting great shots. So I turn the tables. Shoot the Canon with the E-M5 + 45/1.8. Wow again. Beautifully sharp shots with the black camera exposed perfectly. We may have something with this E-M5 thing. This is hardly a fair comparison. The 40D is many years old at this point, and the 50/1.8 is a $100 lens. But still, I am really surprised that the E-M5 just crushed it by comparison. A rematch is looming in a few weeks, when U8 soccer starts. I plan to shoot them head-to-head. Based on a few shots at practice with the E-M5 I am installing the Canon as a fairly heavy favorite to maintain it's title of "Sports Shooter". The E-M5 did OK, but it just can't track action all that well. I ended up shooting wider than I prefer to keep subjects in frame, and even with that my keeper rate was lower than I'd expect with the 40D. I am going to remain hopeful about the E-M5 though. I'd love to dump the DSLR rig in it's entirety.
