Thanks. so are you saying that a 6x7 lens of 100mm f4 would be equivalent to a 35mm lens of 50mm f2, but the 6x7 lens wold still provide less DOF ?
I'm saying that the perspective of a 6x7 camera with a 90mm lens is about the same perspective as a 50mm lens on a 35mm camera. The only difference is that the 6x7 camera with a 90mm lens has less depth of field than a 50mm at the same focused distance. Feel free to correct me if I'm wrong.
