Leica 28mm f/1.4 Summilux-M ASPH Aperture Series: Waning Sun on Aspen Winter Wonderland, Lundy Canyon (Leica M10 Monochrom)
This series from f/1.4 through f/11 examines total imaging performance of the Leica 28mm f/1.4 Summilux-M ASPH. Sharpness near-to-far and across-the-field along with field curvature, focus shift and general imaging performance.
Of particular interest here is showing how to focus for a scene like this so as to achieve peak total sharpness given the field curvature and focus shift behaviors.
Includes images from f/1.4 through f/11 at up to full resolution, plus crops.
Overall I’m really pleased with this series—this is exactly the kind of subject that sings in black and white—color would have only been a distraction and raw conversion headache. But sadly (for me), the black-dot pimple problem pervades the fine details of the fine aspen branches. My finest images from this trip are all mangled by this unacceptable image quality defect.
