Visual inspection of the entrance and exit pupils confirms a significantly telecentric (retrofocus) optical design, therefore one might hope for relatively good performance on the Sony A7R in the peripheral areas without excessive stopping down.
Shot at the close focusing limit, performance ought to remain high; as noted by Leica:
A new design of the interior focusing significantly enhances the quality in the close-focus range through an adaptation of the floating element principle.

- 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.
