Aperture Series in 1/2 Stops with Voigtlander Nokton 50mm f/1.1
Published in Guide to Leica is an aperture series for the Voigtlander Nokton 50mm f/1.1 from f/1.1 - f/16.
The 9-stop series includes the full-frame, as well as a variety of actual-pixels crops, all covering the full aperture range, for a good demonstration of bokeh, vignetting, sharpness.
If you’re a Leica M user, the Voigtlander Nokton 50mm f/1.1 is a bargain. Snap one up is my advice— it’s 1/10 the price of the unobtanium Noctilux-M.
