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… [Read More]
Fujifilm 30mm f/5.6 T/S lens — medium distance field curvature
Lensrentals has loaned me a Fuji GF 30mm f/5.6 tilt/shift lens. I tested field curvature a subject distance of about 25 feet, using the Roger Cicala quick and dirty method (Photoshop>Filter>Stylize>Find Edges). Looks like the moustache field curvature that we saw in the close range images in the last post. The sharpness of… [Read More]
Fujifilm 30mm f/5.6 T/S lens — close range field curvature
Lensrentals has loaned me a Fuji GF 30mm f/5.6 tilt/shift lens. I tested field curvature a subject distance of about 8 feet, using the Roger Cicala quick and dirty method (Photoshop>Filter>Stylize>Find Edges). Looks like moustache curvature. Creating a composite of the two images, with the lens axis about 65% of the way from the left… [Read More]
Fujifilm 30mm f/5.6 T/S lens — distortion
Lensrentals has loaned me a Fuji GF 30mm f/5.6 tilt/shift lens. I measured distortion at about 10 or 12 foot subject distance with the lens on a GFX 100 II with shift and tilt zeroed out. This image was developed in Lightroom with lens profile corrections off. I added the red line at the top… [Read More]
Fujifilm 30mm f/5.6 T/S lens — measuring tilt error
Lensrentals has loaned me a Fuji GF 30mm f/5.6 tilt/shift lens. In the previous post, I looked at tilt-related focus error as a function of the amount of unwanted tilt at various apertures. In this post, I’ll test my (borrowed) copy of the 30/5.6 GF T/S lens for tilt-related focus error. I can do this… [Read More]
