Comparing Sony A7R IV to Sony A7R III Resolution on a Siemens Chart
This page sets looks at an idealized target (Siemens chart), which can demonstrate the best possible sharpness unambiguously. It presents findings which are definitive as to the peak potential of both cameras under ideal conditions.
There is a much to be learned here, and from f/2 to f/11 for both cameras:
- Detail capture.
- Differences in sharpness and micro contrast when processed normally vs with Enhance Details vs 4-shot pixel shift.
- Effects of diffraction from f/2 through f/11 for both cameras.
- Moiré and aliasing behavior.
