I have had some time to evaluate the Hartblei 40/4 TS on a D800E.
Quick question. If you stitch three images, one fully shifted left, one unshifted, one fully shifted right, using your d800E and the Hartblei, what is the final aspect ratio? Is there enough leeway to gain a double width image (ie a 72MP 3x1 instead of the normal 36MP 2x3)?
If such a thing was possible I'd welcome it. I'm into the 3x1 ratio and big prints. At present I'm stitching 8 protrait images on a Canon 5DII, which is a real pain. It can take several minutes to finish one series if the light is low. A nightmare of changing light conditions. Less images, means less time. Also using shifting instead would eliminate potential stitching errors and give me better DOF control via tilt. Tempting - if it can shift far enough for a 3x1.
