This series was shot after I (finally) understood the focus instability problem with the Leica 75/2 and achieves as good a result as possible.
This aperture series looks at imaging performance from f/2 through f/8 on the Panasonic S1R in Multi-Shot High-Res mode. Sharpness, bokeh, and secondary color are looked at.

Leica 75mm f/2 APO-Summicron-SL Aperture Series: Huge Pine Among Aspen
Images at up to 125 megapixels plus crops along with extensive commentary. The imaging quality is spectacular. I want this extraordinary $4750 lens in spite of its focusing instability, but I don’t see it ever being in my budget.
