Examples: 50/2 Summicron Aperture Series (Golden Gate)
On this page we explore the optical performance on an outdoor scene, showing that there appears to be some minor field curvature at infinity focus, and that stopping down to f/5.6 provides tremendous sharpness on the Leica M9.
Exposure
The f/2 frame received 1 more stop of exposure than the other frames (1/4000 second), with the subsequent frames being shot one frame darker (e.g. 1/4000 for f/2.8) and given +0.5 stop exposure compensation.
The scene is of the Golden Gate Bridge in San Francisco on a beautiful summer day, because if you have your health, all days are beautiful. Well, it was dreary and cold and windy on this June day, so windy that I was forced to take shelter behind a tree even while wearing a warm down jacket (WM Flash XR).

- 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.
