Okay, I've hung around here long enough and learned great amounts and been entertained at the same time. Can someone point me in the direction of a post (I've searched) or answer me this:
How exactly do you read these patents when they come out? I see the aperture and the film plane, but what about the focal length? Is it apurture-FP? Is it the same basic concept in all modern lenses?
Thanks,
Bob
