Lensrentals has loaned me a Fujifilm 30mm f/5.6 GF tilt/shift lens. I’m getting ready to send it back, and I asked on DPR if there were any tests that anybody wanted me to run. One reader asked that I compare the sharpness of shifted images vs ones that applied the same sort of corrections in postproduction.
The results will of course depend on where in the image you look. I put the target in about the center of the image.
Some crops at about 150% magnification:
At f/5.6, the shifted image is less sharp than the Photoshop corrected image. At f/8, they’re about the same.
I’m curious, does Fuji write shift amount to the exif?
