This f/4.6 - f/16 aperture series evaluates the Leica 30-90mm f/3.5-5.6 Vario-Elmar-S ASPH on the 37-megapixel Leica S Typ 006.
Includes entire-frame images up to 6048 pixels wide (24+ megapixels) as well as large crops across the aperture series.
Image below has been considerably improved from the dulling effects of diffraction by using the technique described in Mitigating Micro Contrast Losses from Diffraction Blur.
As resolution increases, sharpening technique is especially critical for stopped down apertures; Leica S images go visibly less crisp by f/9.5 due to diffraction, and by f/11 on the image is greatly affected.
