Leica 50mm f/2 APO-Summicron-SL ASPH Aperture Series: Landslide Hillside (SL3)
re: Leica SL3 vs Sony A7R V: In-Depth Value Comparison
This page shows-off the high resolving power of the 60MP Leica SL3 sensor while detailing the somewhat erratic optical behavior of the Leica 50mm f/2 APO-Summicron-SL ASPH.
This f/2 - f/11 series teaches about the capabilities of lens vs sensor and performance as the lens is stopped down.

What I saw was, if I wanted shallow DOF, the Sony FE 50/1.2 GM is better than the Leica 50/2 APO-Summicron-SL. Even at f/5.6, the Sony has a shallower DOF than the Leica.
So for portraits / people, the Sony is a better lens, especially considering I can get far better eye AF with either the Sony A1 or Sony A7R V. But for landscapes, buildings, cityscapes, etc., the Cosina Voigtlander FE 50/2 APO Lanthar is a fantastic lens that just pulls in more DOF out of thin air. So much so that I really thought they were peddling an f/2.8 or f/3.5 lens as an f/2, and I had to take test shots with this lens and another 50mm lens, both at f/2 and both at the same ISO to verify that the camera was taking the same exposure time!
An amazing lens. So a Sony A1 + Sony 50 f/1.2 (for people / street photography) or an A7R V + CV 50 f/2 APO Lanthar (landscape / cityscape) are both better solutions for their respective use cases than the Leica SL3 + Leica 50 f/2 APO-Summicron-SL.
DIGLLOYD: not sure about the relative sharpness, but a lens with focus shift is de facto less sharp, and the Leica 50/2 APO-SL has that issue.
