Distortion: 28mm f/2 Summicron-M ASPH
Distortion is low for a 28mm lens, but shows up on buildings or even horizons. Yet few 28mm lenses have distortion this low.
The distortion is not strictly uniform barrel distortion; it “flattens” slightly at about 2/3 from center. This could make it more difficult to correct in software, but it is probably close enough.
That said, the 1% distortion is very low and on most subjects it will not be detected by the eye— except for architecture, see the example below.

- 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.
