Subject: [Leica] 28mm Summicron vignetting

Here are a few examples of vignetting using the 28mm Summicron. These  
were shot in b&w but the sky was crystal clear blue. These were shot  
by my son at Zion, Bryce and the Grand canyon.

I'm not sure of the f stop but I believe they were in the f5.6 to f8  
range. We ran a test in my backyard of the Summicron versus the  
Elmarit (not asph). The Elmarit had a little less vignetting. All the  
examples were easily fixed in Photoshop using the lens distortion  
filter.
