Leica R to Leica M adapter R-Adapter M

Mitigating Vibration Caused by the M240 Shutter

See the overview of the Leica R-Adapter M and the general field shooting notes for R-Adapter M.

The shutter in the Leica M Typ 240 itself causes enough vibration that special care is needed. There is no true solution (only mitigation), and yet Leica could make some operational changes to improve the odds.

Loss of image sharpness in a certain shutter speed range was observed in virtually every sequence in the field with 180mm and 280mm lenses, regardless of which tripod was used (small or large), and whether a lens tripod foot was used versus the tripod foot on the R-adapter M. It’s harder to assess shorter forcal lengths, but if the setup is not rock solid, issues might be seen down to 90mm.

  • 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.
