Recently I purchased Leica’s new 21mm super elmar. All I can say is WOW! The sharpness and minimal distortion is phenomenal. Last, I love using “zone focusing“. I just set my aperture and shooting distance and I’m ready to go. If you set your aperture to f/8 (has to be a sunny day) and shooting distance to 5 feet, anything beyond 3 feet will be in focus.
This shot was taken from the hip. This guy was definitely on the go.
