Thanks mediumformatfan. This is ~ a 40% crop of the full frame. The foreground has been taken out. I set up the camera using a Manfrotto Spirit Level so no adjustments were necessary this time. Sometimes, no matter how careful you are, one does not position the camera "dead centre"/perpendicular to the subject and the image then needs a small bit of centering using the Left/right adjustment in DxO plus a tweak to the Horizontal. DxO is just amazing for corrections to Geometry. Steve
"The resolution of the Zeiss lens is very high straight from f/2.8. The peak quality is reached at f/5.6 but there're only minor quality variations across the tested aperture range actually."
"there're only minor quality variations across the tested aperture range " - I would agree with this statemement. As one might expect, the results tend to be sharper out into the corners of the Frame at Apertures > f/4. Many of these images will be printed so corner performance is quite important. Viewed on a Monitor, the difference may not be as obvious unless you have access to the full file and view the corner quality at 100%.
Nice photo, very sharp as usual, I look at the other Photo's from you.
Most of the time you are shooting with F8 , F11 maybe the sweetspot for the zeiss 21mm ?
