Infrared with B+W 092 Filter
This page looks at the near infrared response of the Leica M11 Monochrom sensor. Using such filtration extends the useful range of capture tonal relationships.
The M11M places a UV and infrared-blocking filter over the sensor. This is done to improve general image quality by blocking wavelengths that would otherwise cause a reduction in contrast primarily by differential focus (eg longitudinal chromatic aberration). But it does allow near-infrared to pass.
One might posit that Leica should also offer the camera as a full-spectrum variant, blocking neither UV nor IR and thus offer a camera no other company does, short of custom conversions. Or an infrared-only or UV-only variant for that matter. But... dilettante custom finishes and collector trinket versions will surely take priority over useful capture variants.

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.
