January 1, 2022 JimK 1 Comment

  In the previous post, I compared the Fuji 35-70 GF against the 32-64 GF using foliage as the subject. I looked at the center of the images there; now I’ll look at the corner performance. I set up the GFX 100S as follows: RRS 4-series Versa legs Arca-Swiss C1 2-second self timer ES ISO… [Read More]
