June 2013 lens sample, which suffered from poor flare control.
These examples shot in the White Mountains of California and Yosemite National Park.
The intent of this series was to explore sharpness at wider apertures, but even more so to explore subject separation and bokeh possible at wider apertures, the f/2 maximum aperture being handicapped by a full stop versus the 50/1.4 Summilux and two stops over the 50/0.95 Noctilux.
In general, subject separation is often degraded by field curvature: an uneven sharpness curve (non-planar) distracts by making mid-zones or edges/corners sharper forward or back of the nominal plane of focus; the Noctilux could almost be said to be notorious in this regard, with its rearward sharpness curve to the edges and corners (see the Garlic example).

Special emphasis is placed on Leica M lenses and certain Zeiss ZM lenses.
- 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.
