How to vignetting with P25 ?

Postby NN636844300459538251UL » Wed Jan 30, 2019 7:31 am

I document artwork, and have trouble with vignetting. I use a Mamiya 645AFD with an 80mm macro , 55-110 mm, 80mm normal lens and a 35mm wide angle. I find that with any of 4 different lenses I use I have the same amount of vignetting. It averages about 12 brightness points difference from the central area to the corners. The dealer wwho sold it to me tried other bodies and other P25 backs to see if it was a problem with my system, they even replaced my back with another used one. Has anyone had this problem and found a solution?

Have you tried using lens cast correction?
