Lens Impression

Dr.Paul Rudolphが、その人生の最後を飾るようにして自ら設計したMiniature PlasmatをKleinbild Plasmatとして提供(上掲写真のレンズの特許番号がMiniature Plasmatのものと同じということで特定できます。)し、Dr.Winklerの設計によってPlasmat社で開発されたのが、このRolandで、世界初の連動距離計を装備した金属鏡胴式のカメラがこのRolandです。Plasmat社は当初はDr.Winklerの所有だったようですが、後に(1933?)にDr.Rudolphの手に渡ります。残念ながら、Dr.Rudolphは僅か2年後の1935年にこの世を去ることになります。

Being offered the Miniature Plasmat that Dr.Paul Rudolph had himself invented as almost the last monument of his life, as Kleinbild Plasmat (it can be identified as same lens because the patent number of the lens in photograph shown above is the same as that of Miniature Plasmat), and had designed by Dr.Winkler in the Plasmat Co. is this Roland Camera. And this camera was equipped with the world's first coupled range finder in a metal camera and lens body, is also this Roland. The Plasmat GMBH seems to be owned by Dr.Winkler, and handed over to Dr.Rudolph later(1933?). To our regret, Dr.Rudolph departed this world in 1935 after only two years.
This camera was rare 2nd type of the Roland, which the volume of production is rarely few and seldom appears in the market. The optical exposure meter equipped in the 1st type was excluded, however the automatic film winding stop mechanism by one exposure with the interconnected film counter was equipped.
The composition of this lens is similar to the Makro-Plasmat with the difference of the last lens group which of this lens is 2 lenses cemented, on the other hand is separated by each glass in Makro-Plasmat.
As for description, this lens shows the precise and clear image without swirling bokeh or flows of image around peripheral area which is closer to Makro-Plasmat because of the similar composition of lens possibly than Kino-Plasmat.

Developed film was came back and shows a very similar tendency of the description as the last development. Resolution is very excellent as you can see in the 2nd and the 4th photos which are partial expansions of the 1st and 3rd photos respectively. The last photo is of St. Bartholomew's Hospital, in Conan Doyle’s novels, it is well known as the duty hospital of Dr. Watson.

Since I do not have a film scanner, I asked the development shop to burn into CD. Because the resolution of their scanner is low, the original performance does not seem to appear. However, I can feel the high-resolution subscription of this lens and some softness in around at full aperture in these examples.
