eight images from Sony a7r, Sigma SD4H, SIgma Dp1 Merrill. 18-28 comparison
1

Same position on tripod, only jpg out-of-the-camera (sorry for the 16:9 from Sony), same diaphragm (5.6) and (about) same shutter time. Full resolution. Focus ever magnificating the same tree on the right. Nothing to demonstrate (more complete with also modern lenses...I know it), but almost for me interesting.......

My opinion:

-sensors: 1 Merrill 2 Sony 3 (I find it very good especially for monochrome, only I'm a little disappointed from that green zone I often find on the right with moderate/low light as here..) SD4H.

-lenses (apart the Merrill) very good both the Zeiss Distagon, weak the Olympus and the Flektogon, too bad to be true the Leitz (I think there is some problem in focusing or with the adapter).

Let me know your opinions, and all the best,
