I am sports photographer and still love my 7D. With the higher ISO, it has been great for low light sports. The 8 frames per second is wonderful. the only draw back is this drops significantly as battery power wanes. This camera opened up new possibilities for me. While I want to upgrade to bigger and better, I want to always have a 7D with me. I recommend the vertical grip battery pack for this as well. This camera opened up a whole new world of possibilities for me to shoot. Image Quality This does great in low light especially up to ISO 2500. At 3200, I start seeing some grain. Performance No issues here. I would buy again and again. From time you power up until you are shooting is less than one second. Ease of Use For anyone new to the Canon camera line, this may take some time, but if not, it is easy to learn. Durability Had mine for 3 years and it has held up beautifully!! I have taken care of it, but have used it non stop since I got it.
