Sigma FE 85mm f/1.4 DG DN Art: Micro Contrast, Moiré, Color Aliasing with/without Pixel Shift and Distortion Correction
The Sigma FE 85mm f/1.4 DG DN Art is an exceptionally sharp lens wide open at f/1.4, so it is a fine candidate for this study of how image quality can be degraded by a variety of factors.
How to get the best possible results?
Conclusive results are shown as to the effects on micro contrast, color aliasing and moiré from f/1.4 to f/11 from all of the following:
- Diffraction effects.
- Distortion correction for its pincushion distortion.
- Single-shot vs pixel shift vs Adobe Camera Raw Enhance Details.
Sigma 85mm f/1.4 DG DN Art: Distortion and Distortion Correction
Includes images from f/1.4 through f/11 in 6 variations: {single shot, single shot enhanced, pixel shift} with uncorrected and corrected-for-distortion versions.
