Leica 28mm f/2.8 Elmarit-M ASPH

Vignetting: 28mm f/2.8 Elmarit-M ASPH

The change in field illumination is entirely done by f/5.6. All that remains is the natural vignetting governed by optical laws for this kind of lens construction.

The difference from f/2.8 to f/5.6 is of little consequence for most every image; it’s there, but not very noticeable.

  • 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.
