Aperture Series: Animal Tracks near Snowy Creek, Lundy Canyon (Leica M10-R)
This series from f/1.4 through f/11 examines imaging performance of the Zeiss ZM 35mm f/1.4 Distagon focused at medium distance distance through an intermediate zone with strong demands on near to far depth of field.
Includes images from f/1.4 through f/11 at up to full resolution, as well as a 3-frame focus stack at f/9, plus crops.
Animal Tracks near Snowy Creek, Lundy Canyon
Adobe Camera Raw 13.1.0.658. View ACR settings. Diffraction mitigating sharpening for f/9 (modest). Vignetting correction.
Focus was near center, which leaves both the background and foreground well out of focus, showing us secondary color aberrations plainly—the far background has plenty of magenta/green color bokeh, which mostly cleans up by f/2.8. At wider apertures, the foreground has some magenta tinge and the background a greenish tinge—always the case for any lens which is less than a very highly corrected APO lens, which the ZM 35/1.4 is not.

- 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.
