I have been using my old 50D for years for macro and product photography, and have just recently started into bird photography. Yes, with my 50D - and a 300mm f4 canon plus tc. Not exactly top-of-the-line, but for my purposes, it worked well enough for the controlled light imaging I was used to doing. So when I took it out in the early morning to get the grebes, I didn't expect much. I'm quite pleased.
