Aperture Series: Barcroft Blue Building (M240)
At the time this series was shot (first experience with the R-Adapter M), the issues of M240 shutter vibration were not well understood. As a result, the series suffers a loss of quality at f/5.6 due to shutter vibration damage at 1/30 second.
Leica R-adapter M used via tripod foot mount with 2-second self-timer and Light Metering Mode = Advanced ('Classic' with Live View off is better). The shutter vibration danger zone centers around 1/30 second. 2-second self timer with Light Metering Mode = Advanced.

- 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.
