Zeiss ZM 50mm f/2 Planar

Veiling Flare ZM 50/2: Shaded and Unshaded

On Leica M Type 240. No filter was used and the lens shade was attached.

The goal here was to maximize flare: the camera was placed on a tripod, then was rotated and angled in order to achieve the visibly worst case flare without having the sun directly in the frame (it is not necessarily worse to include the sun and might actually be better, but this was not the goal).

Two images were taken at f/11 with the lens focused at infinity: one unshaded and one with the front of the lens shaded from strafing non-image-forming light (the sun).

Example at ∞ focus

The shading of the front element by the lens hood does not change with focus (distance between the front glass and lens shade is unaffected by focusing).

  • 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.
