Color Shading for M-Mount lenses on Sony NEX-7
This page offers color shading aperture series for a selection of M-mount lenses: Leica M, Zeiss ZM, Voigtlander on the 24-megapixel Sony NEX-7. See the Color Shading general discussion.
By using the Sony NEX-7, we can eliminate any Leica lens corrections, and see the true lens behavior, albeit on an APS-C sensor, which is cropped by a 1.6X factor over the full-frame Leica M9 sensor. Of course, the built-in correction of the M9 is of real value, and one solid reason to use Leica M coded lenses on the Leica M9/M9P. Still, the increasing use of ALLVIEW cameras means that knowing the raw performance of all M-mount lenses is very helpful.

- 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.
