Is it generally possible to calculate a lenses coverage by knowing it's design and focal length? Obviously individual copies of lenses are going to vary somewhat, but on a general basis is it possible to say- this lens is a Plasmat so it's going to cover XX degrees, this is a Tessar so it will cover Y degrees? If so does anyone have a list of lens coverages by design?
I'm hoping to add a lens coverage calculator to the (free) LF Android App I'm developing.
