Leica 28mm f/1.4 Summilux-M ASPH Aperture Series: View Over Alabama Hills to Lone Pine Peak and Mt Whitney (Leica M1-R)
This series from f/1.4 through f/11 examines total imaging performance of the Leica 28mm f/1.4 Summilux-M ASPH on a distance scene, which is unforgiving of lens fault. Sharpness near-to-far and across-the-field along with field curvature, focus shift and general imaging performance. Also, a surprisingly strong amount of violet fringing.
Includes images from f/1.4 through f/11 at up to full resolution, plus crops.
Call me unimpressed. Sony mirrorless has nothing to apologize for.
