Field Curvature on the Fuji 45-100/4
Inspired by Hamiltonian on DPR, I applied Roger Cicala’s field curvature visualization method (Photoshop: Filter -> Stylize -> Find Edges) to the 45-100/4, at putative focal lengths of 45, 60, 80, and 100mm: Top left is 45mm, top right is 60mm, bottom left is 80mm, and bottom right is 100mm. The top… [Read More]
