Congratulations Bob on your new purchase. The 7D was my first DSLR but I have tried the 50d. The biggest differences for me (besides movie mode, I dont use it much) are the viewfinder and ISO performance. The 7D viewfinder is awesome, I love it. ISO performance is probably the biggest difference for me. Comparing the 50d and 7d at ISO 3200 is like comparing opposite ends of a greyscale; for me at least there's no competition.


Good Luck with your new Camera!
