Leica M Monochrom Typ 246: Aperture Series to Assess Diffraction and Digital Artifacts (Dolls)

Get Leica M Monochrom Typ 246 at B&H Photo.

See my review of the original 18-megapixel Leica M Monochrom in Guide to Leica and the summary of the new Leica M Monochrom Typ 240.

This aperture series assesses the effects if diffraction from f/2 to f/16 and shows diffraction mitigation results at f/11 and f/16.

Leica M Monochrom Typ 246: Aperture Series to Assess Diffraction and Digital Artifacts (Dolls)

Includes full resolution images (24 megapixels) and crops.

It is odd to find what appears to be digital artifacts in a monochrome sensor camera, but there it stood out (not shown here), found while assessing the scene for diffraction. Disabling sharpening leaves the apparent artifacts in place, so it’s not a result I yet understand.

Together with the ISO assessment, this series gives a good core understanding of the technical performance envelope of the Leica M Monochrom Typ 246.

Dynamic range appears good, but well short of the Nikon D810, and I’m unsure whether the MM246 can deliver more detail than the Nikon D810—to be tested in the field.

I’m getting some field experience with the new Leica M Monochrom Typ 246. When I return from the Yosemite area, I’ll be publishing my examples and impressions as part of my review of the Leica M Monochrom Typ 246.
