DR Summicron is a Summicron 50mm lens that enables close-up photography up to 0.48m by attaching glasses (close-up adapter). The gimmick is mechanical; when the glasses are worn, the ball is pushed in, allowing the helicoid to move into the melee area. When glasses are removed from the lens, the lens focuses within a range of ∞ to 1m and can be handled like a regular lens.

The stopper parts on the glasses are designed to match the overall height of cameras before the M6, so glasses cannot be attached to cameras after the M6-TTL, which have a higher overall camera height. You can put them on by removing the stopper, and you can sometimes see second-hand glasses with the stopper removed.

The silver chrome exterior of this era is very beautiful, and the knurling on the focus ring is elaborately made, something you wouldn’t find on a modern lens, making it a satisfying lens to own. Since this lens was produced in large numbers, there are many in good condition, and if you search a little, you should be able to find the one you like. Before 2010, lenses for eyeglasses were sold at a fairly low price, but in the 2020s, prices have increased like other lenses.

As you can see from the photo with the lens attached to the camera, the lens with glasses spoils the lightness of a rangefinder camera, but it gives the camera a mechanical and solid feel. If you attach the grip and glasses as shown in the photo, the whole camera will be quite heavy, and it will be a little difficult to hang it around your neck, but it will definitely make you stand out.

When I was using a film camera, I liked this because it allowed me to take close-up shots, but with the M Digital, the stopper part got in the way, so I didn’t use it much anymore, so I sold it. . If I were to get Film M again, this is the lens I would want to buy together, and I think it’s a lens from the good old days.
