Leica 50mm f/2 APO-Summicron-M ASPH

Leica 50/2 APO ASPH Flare (April 2013 Sample)

June 2013 lens sample, which suffered from poor flare control.

On Leica M Type 240. No filter was used and the lens shade was fully extended.

Flare control with the 50mm f/2 APO-Summicron-M ASPH is problematic when shot towards the sun; severe amounts of veiling flare and some ghosting flare are apparent.

Field shooting with another lens sample and another M Typ 240 camera body shows that the resuls seen here are not sample specific and are problematic under many conditions that one wishes to enjoy photographically.

No particular effort was needed to generate abysmal results, and choice of aperture had no influence on the flare shown here. This is not to say that it will always occur, just that it occurred over and over under these conditions without making any special effort, indeed while trying to avoid the flare by changing position slightly.
