Just published in my Guide to Leica is a new aperture series from f/1.4 - f/16 with the Leica 35mm f/1.4 Summilux-M ASPH FLE.
Large actual pixels crops as well as 2048 pixel full-frame images, all at the full f/1.4 - f/16 aperture range.
The 35/1.4 Summilux-M ASPH FLE has some limitations for this type of scene, all of which I describe and show in detail. The fine detail all at a similar distance allows analysis of lens performance over the entire frame.
Recommended reading not just for Leica shooters.
