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