Fuji 32-64/4 focus shift and parfocality
This is the fourth post in a series of tests of the Fujifilm 32-64 mm f/4 lens on the Fuji GFX 50S. The test starts here. The data in the previous post can be reworked to show focus shift as the lens is stopped down: At 64 mm, the focus shift is moderately low. Except… [Read More]
Fuji 32-64/4 LoCA
This is the third post in a series of tests of the Fujifilm 32-64 mm f/4 lens on the Fuji GFX 50S. The test starts here. In order to test on-axis longitudinal chromatic aberration (LoCA), I use computer controlled focusing rail and a razor blade target. A quick review of the test protocol: Fuji GFX 50S… [Read More]
Fuji 32-64/4@64mm tilt, field curvature, & astigmatism
This is a continuation of the development of a simple, relatively foolproof, astigmatism, field curvature, and field tilt test for lens screening. The first post is here. It is also the second post in a series of tests of the Fujifilm 32-64 mm f/4 G-mount lens for the GFX 50s. That test starts here. Brandon… [Read More]
