On Leica M Type 240. No filter was used and the lens shade was fully extended.
Stray light can come from any direction so it is very worthwhile to pay attention to all areas of the frame and block this stray light. Handheld this is awkward, but on a tripod it is straightforward using Live View to make the check for haze. The trick is with a 2-second self-timer to not wander the hand into the frame! Hence retries might be needed for angles very near a light source.
Examples at ∞ focus
The shading of the front element by the lens hood does not change with focus (distance between the front glass and lens shade is unaffected by focusing).
The goal here was to maximize flare: the camera was placed on a tripod, then was rotated and angled in order to achieve the visibly worst case flare without having the sun directly in the frame.

- 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 28 megapixels filling up to 5K display, 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.
