5 Frames with a Leica Summicron DR 50mm f/2 on a Leica M240 – By Steven Bleistein

The first lens I procured for my Leica M3 body was a 1958 Summicron 50mm f/2 Dual Range (DR). The Dual Range is unique among Leica 50mm Summicrons because it allows for close range focusing down to 0.478m as opposed newer models which focus down to no less than 0.7m. To achieve the close-up range, the DR is paired with detachable optics that not only optimize the magnification of the finder for close range, but also correct the angle of view and so adjust for parallax.
