Shown here are a few examples from the Zeiss ZM 18mm f/4 Distagon taken when I first started using the M9 with its original firmware, but they are sufficient to show that the 18/4 is a very sharp lens with very high contrast— and that some kind of lens correction is needed, such as using the Coder Kit to deal with some of the vignetting.
Aperture not recorded
All apertures are “best guess” from memory— the M9 does not and cannot know the aperture at which the exposure is made. The notation ~f/8 means “f/8 or thereabouts”.
An 18mm yields a strong perspective with accompanying geometric distortion towards the corners (not an optical effect), making it a challenge to shoot. But the extremely low distortion of the 18/4 Distagon reduces true optical distortion to about as one as one can expect with an 18mm lens.

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.
