Sharpness Losses from Field Curvature at Distance: Grassy Meadow
This aperture series from f/1.4 through f/5.6 looks at the pronounced field curvature of the Leica 50mm f/1.4 Summilux-SL ASPH, showing why the lens is a poor choice for landscape work at a distance, as with this scene.
A lens that cannot render sharpness across the frame even at f/5.6 means that it has no versatility, and cannot be relied upon to perform for any image where sharpness must cover the frame, or for any planar subject, or for astrophotography. This series proves that the Leica 50mm f/1.4 Summilux-SL ASPH is just such a lens.
