This is a continuation of — and a sidebar to — the development of a simple, relatively foolproof, astigmatism, field curvature, and field tilt test for lens screening. The first post is here. I took the simulator and set it up for a camera with a 5.3 um pitch, 60% fill factor, and a diffraction-limited lens…. [Read More]

In the previous post of this series, I simulated the “pillows” that appeared in the Siemens Star images made with the Fuji GFX 50S and the Fuji 110/2… [Read More]
