This series from f/1.4 through f/16 examines imaging performance of the Zeiss ZM 35mm f/1.4 Distagon focused at far distance through an intermediate zone.
Aperture f/11 is subject to moderate diffraction dulling for fine detail, and f/16 much more so. However, while f/16 is impacted in a major way on a 60MP sensor, with the 40MP sensor of the Leica M10-R, diffraction effects at f/16 remain tolerable when diffraction mitigating sharpening is used. Good behavior is not a given however. While the ZM 35/1.4 is exemplary, far more expensive Leica 28mm f/1.4 Summilux-M ASPH does a lousy job at f/16. It’s not just about diffraction, but about internal lens flare from collimited rays.

Diglloyd Guide to LEICA contains in-depth coverage of Leica M system cameras and lenses, with additional coverage of Leica M Monochrom, Leica Q.
Special emphasis is placed on Leica M lenses and certain Zeiss ZM lenses.
- Make better images by learning how to get the best results right away.
- Save money by choosing the right lens for your needs the first time, particularly the Summilux/Summicron/Elmarit choice and/or Zeiss ZM.
- Make better images, a sort of “cheat sheet” saving yourself months or years of ad-hoc learning. Processing parameters are discussed and shown.
- Jaw-dropping image quality found nowhere else utilizing Retina-grade images up to full camera resolution, plus large crops [past 2 years or so].
- Real world examples with insights found nowhere else. Make sharper images just by understanding lens behavior you won’t read about elsewhere.
- Aperture series from wide open through stopped down, showing the full range of lens performance and bokeh.
- Optical quality analysis of field curvature, focus shift, sharpness, flare, distortion, and performance in the field.
