M240 at 28mm vs Sigma DP1 Merrill: Native Resolution

The 28mm f/2 Summicron-M ASPH and 28mm f/2.8 Elmarit-M ASPH represent Leica’s best 28mm efforts as of mid 2013. How do they perform on the 24-megapixel Leica M240 against the Sigma DP1 Merrill?

The about $899 Sigma DP1 Merrill (“DP1M”) incorporates a fixed 28mm f/2.8 (equiv) lens on an APS-C sensor. [Its two siblings offer 45mm and 75mm options with the same sensor. All are reviewed in Guide to Mirrorless]. The Sigma Foveon X3 sensor is 15 X 3 megapixels producing 14.75-megapixel finished RGB images. It has no need for an anti-aliasing filter and does not suffer from the digital artifacts (moiré, color aliasing, jagged edges, etc) seen with conventional Bayer matrix sensors e.g., the CMOS sensor in the Leica M240.

  • 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.
