I test for focus curvature with Roger Cicala’s method. In Photoshop, Filter>Stylize>Find Edges.
- X2D 100C
- 90mm f/2.5 XCD
- ISO 64
- 1/1400 to 1/1700 second, electronic shutter
- AF-S (the only find there is)
- Developed in Lr with default settings
This is excellent performance. The focal plane for the edges are a tiny bit closer to the camera than they should be for a rectilinear lens. Also, there is very little sharpness falloff off axis.
