M240 at 28mm vs Sigma DP1 Merrill: Matched Resolution

This page compares the M240 + 28mm f/2.8 Elmarit-M ASPH against the Sigma DP1 Merrill using the same image as the prior page; that page used native resolution for all, but this page uses matched resolution.

See the testing comments on the M240 + 28mm vs Sigma DP1 Merrill Native Resolution page.

To match the resolution without a native vs non-native bias, images were all forced through an upsampling + downsampling cycle as follows:

  1. Upsampled to 9000 pixels wide
  2. Downsampled to 5600 pixels wide (a very slight reduction for the M240 from 5976, and a 19% linear enlargement for the Sigma DP1M).
  3. Mild sharpening.

  • 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 28 megapixels filling up to 5K display, 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.
