60MP Sony A7R IV
Sony FE 20mm f/1.8 G

Aperture Series: View Over Dry Wash to Early Sun on Mt Whitney Range

This series from f/1.8 through f/8 evaluates the Sony FE 20mm f/1.8 G on a near-far distance scene and looks at total sharpness near to far and edge to edge.

Shot in pixel shift mode, to my surprise and delight the pixel shift images worked well and are used here, thus showing off the true resolving power of the lens with a stunning level of detail.

Includes images up to full 60MP camera resolution.
