Hello everyone -- I am new to the photography world. I am in the process of buying a camera and a lens. I will be taking inside sports photos such as basketball, volleyball, wrestling, etc and outside photos during daylight hours and at night ... I was told I needed this lens: Canon's 70~200mm f/2.8L lens .... I purchased it -- My question is this -- That lens obviously cost me some good cash and I wanted to know if I could save some money when I buy the camera? Which cameras work with this lens and which one would you guys suggest? I am on a budget and I stretched it with the lens. Thanks so much!
