How does focussing distance relate to image size? I
mean, If I set a power zoom lens to keep the subject
filling say 75% of the viewfinder how does distance
factor into this equation?
Anyways, I would be surprised to find it is just the
camera; since there is no such problems with any other
lens. Why the lens works on the z1p is a mystery
though.
