Direct sunlight or other bright light onto the front lens elements generates severe flare:
- Direct sunlight or similar non-image-forming bright light that grazes the front element causes a severe veiling flare (haze).
- Strong backlighting is prone to generating a veiling flare.
- Certain ghosting flare (blue orbs) are seen wide open and 1/2 stop down. Field use suggests that this resolves at f/2.8 under most circumstances.
The round lens shade on the 75mm f/2 APO-Summicron-M is entirely inadequate for many shooting situations. Always shield the front lens element from direct light. This is true of many Leica M lenses, and most lenses in general.
Veiling flare from sunlight striking front lens element
When sunlight as non-image-forming light hits the front lens element, all heck breaks loose, as shown. This type of flare is not improved with aperture (stopping down).

Diglloyd Guide to LEICA contains in-depth coverage of Leica M system cameras and lenses, with additional coverage of Leica M Monochrom, Leica Q.
Special emphasis is placed on Leica M lenses and certain Zeiss ZM lenses.
- 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.
