Hi,
Newbie question: How do I figure out the coverage of a lens? The only measurements I have are a diameter of 5.3cm and length of 5.8cm. Someone's trying to sell it to me and I want to make sure that it will cover 6x7 (or larger).
Also, I'm guessing I wouldn't be able to figure out the max aperture without more info, correct?
Thanks,
Mark
