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.
