I guess this question has two parts: Is there a simple calculation that gives the 35mm equivalent for a lens on a larger format? For instance a 48mm lens on a 36x48mm sensor in 35mm equivalent? Is there a calculation that allows you to calculate the (horizontal) 35mm equivalent of the same lens on the same sensor when shifted, say, 10mm left then 10mm right?
I'm sure there must be, I just can't find it.
