Leica M Monochrom Typ 246

Compared: Leica M Monochrom Typ 246 vs Leica M Typ 240 (Lee Vining Canyon)

Here are compared the Leica M Monochrom Typ 246 to the Leica M240. Both are 24 megapixels utilizing the same sensor technology (an ideal comparison!). The MM246 omits the Bayer matrix color filter array (CFA) found on the M Typ 240 sensor.

A monochrome sensor ought to have inherently higher detail resolution and also a freedom from aliasing. The color sensor should deliver reduced resolving power along with color aliasing speckles and spurious resolution, due to the demosaicing process required for its Bayer-matrix CFA sensor.

Lee Vining Canyon

This scene was chosen for its invariant lighting and preponderance of very fine detail that is right at the limits of sensor resolution. The Leica 24mm f/3.8 Elmar-M ASPH was used at f/8; it is about as sharp and flat field as a lens gets. No filters were used; this is clear mid-day harsh lighting.

  • 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.
