[Leica] RD 1 Vignetting with the CV 15 Heliar

[cummer at netvigator.com (Howard Cummer)]

Hi Ernie
See the following URL for examples of vignetting with the CV 15 Heliar 
on the RD 1. The first picture is corrected using Epson's software and 
the second is obviously not. Click on the pictures for a larger view 
and photo details. Photos were shot in RAW - required if you want to 
use Epson's correcting software.

PS: In Luminous Landscape Sean Reid has a recent article on vignetting 
with wide angle lenses on the RD 1 - the 15mm is worse than the 12mm 
apparently. Please see:
