I am trying to shoot middle school basketball. What type of Canon AE-1 Program lens is best for this? And, where can I find the lens?
Your best bet would be to use an FD 200/2.8. The best place to find FD gear is on E-bay.
yea you will want something around 200mm F/2.8. ebay will be your best bet for a good used lens. there might be one in B&H's used section too.
