I was wondering that maybe A1 can be focused to 36x24mm or smaller frame without an expensive achromat as it has quite good close focusing capabilities?
My cad simulation shows that at the widest angle in can focus on 36x24mm frame from ca 25mm but minimum distance required to get rid of vignetting in dof adaptor assembly is somewhere at 50mm.
Can someone please test if A1 can focus a 36x24mm or smaller frame from 50mm to 64mm distance? Focusing on 32x20 frame at 64mm would be perfect.
Thanks in advance,
T
