This sample was taken with the SL66 and focused with one of the two original SL66 focusing screens using the f4 Distagon lens, the natural light came from a little window and I needed a long exposure time to take the photograph, I had no problems to focus the image, it is sharp in the internet and out of the internet: http://www.flickr.com/photos/itarfoto/4716333685 Carlos 2012/1/1 CarlosMFreaza <cmfreaza@xxxxxxxxx>: > 2012/1/1 Jim Brick <jim@xxxxxxxxxx>: >> I was using Hasselblads for decades before getting my Rollei SL66s.
