Back in 2009 I reported on a bifurcated sensor problem with the Leica M9.
Imagine my surprise in 2020 to come across the same phenomenon in the Leica M10 Monochrom. IMO, this renders the camera totally unacceptable, even if it is seen only occassionally, being mostly a problem in smooth tones. But isn’t that one big appeal of a monochrome camera—gradients and smooth tonality? A 1-point hiccup cannot be unseen once seen.
The sensor is apparently imaged during production in two halves, left and right. With the right subject matter such as a sky, the result is differing brightness between the halves, which is perceived as a vertical line dividing the sensor in half exactly at the half-way point: 3932 pixels across the 7864 frame.

Diglloyd Guide to LEICA contains in-depth coverage of Leica M system cameras and lenses, with additional coverage of Leica M Monochrom, Leica Q, Leica SL.
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.
