Hi everyone. I have a question about lenses. I have a manual camera and i know everything about it (almost)... but now i'm buying my husband a camera and i just have no clue about auto focus cameras. My husband has his eye on a canon autofocus camera (rebel something). Just a basic camera so he can learn from. but he wants to put a manual focus on it. Now of course all what i can find are autofocus lenses that say its for that specific camera. I guess what i'm getting at is: do all lenses that are marked to fit canon (despite the model) fit all canon cameras -- can i put a manual lense on the autofocus camera? or do lenses come in certain sizes for each model? I hope this made sense. thank you so much from your input. I'm learning so much since i joined this site. Everyone has been a great deal of help!
