Leica M10 Monochrom

Infrared with Leica M10 Monochrom

The page looks at infrared images with the Leica M10 Monochrom.

As a monochrome sensor, the question surely arose at Leica of what kind of infrared-cutoff filter to use. A substantial amount of near infrared light passes into the sensor, presumably by design. The proof is shown on this page by images taken using the B+W 092 infrared filter, which has a sharp cutoff at ~690nm, which is right around the point where human vision rapidly fades in its ability to see these wavelengths.

Infrared is both a plus and a minus: light in this near-infrared band is sure to reduce micro contrast and sharpness by focusing differently than visible light. But it also means that Leica M10 Monochrom photographers have a monochrome camera that can also function as a near-infrared camera—a huge plus if infrared is of any interest, since no modifications are needed other than screwing on an appropriate cutoff filter.

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.
