I’m selling a very rare lens made by the famous optician Dr. P. Rudolph by the company Kleinbild-Plasmat-Gesellschaft. Now I’m not completely sure why this lens doesn’t have the marking Makro-Plasmat, like so many other pictures I see online, but I think it’s because it’s slightly older, before they renamed the lens to Makro-Plasmat. The full text on around the rim of the lens is Dr. P. Rudolph Kleinbild-Plasmat Sechslinsig 70mm f/2.7. Like the name suggests, Sechslinsig can be translated to six-element or six-lens. This specific lens design was patented by Dr. Paul Rudolph (D.R.P. DE572222) in 1931, and was approved in 1933.
Dr. Rudolph was a highly influential optical designer best known for creating groundbreaking lenses such as the Tessar (for Zeiss) and later the Plasmat lenses.
Condition: One scratch on the front element, no fungus, no haze, very clean glass other than that one scratch. Aperture works nicely, slow shutter at lower speeds.
I don’t have any official payment method or store, but if you’re interested in buying or trading you can email me at espen.susort@gmail.com.
Did you use a hood when taking these? Shutting out extraneous light transforms the results from folding camera shutter – lenses (which are, of course, uncoated and highly susceptible to flare. The brand to look for is ‘Black Cross’, made in a range of diameters to simply clip onto the front bezel of your lens, they are excellent and fairly available. Failing a hood, hold a flat shade of some sort (I use a kitchen chopping board) in front of the lens to stop direct light hitting it. Just hold it sufficiently clear to shade the sun but not so that it is in the field of view.
