A person interested in the LS911 was asking for some sharp portraits. While I love wide open photos with part of an eye in focus, I can see the appeal for sharpness. To take a sharp portrait I used a Schneider Kreuznach G-Claron 9/305 f/9 and stopped down to f/90. After the setup, the model, Miss Z, just took photos on her own with self timer and an iPad.
