Impression
This compact wide-angle lens is not rare, as only about 11,000 were made.
The nickel exterior version is available in the used market at a high price, probably because there are only a few of these lenses.
Because it is an old lens, many of them are cloudy due to balsam breakage on the laminated surface of the front and rear balls.
As shown in the sample images, the lens is more appealing when used with a film camera with a reduced exposure and a reduced focal length.
The compactness of the lens itself is attractive, but at this f-number, I am not inclined to use it only outside in the daytime or mid-night.
When photographed with a modern digital camera, there is almost no vignetting, but some flaws of older lenses can be seen, such as the sweetness of the image depiction.
It used to be a dark and unpopular lens that could be purchased at a low price, but as of 2022, the price has risen, dragged down by the soaring price of old lenses. It is doubtful that it is worth the high price.
Specification
This wide-angle lens was manufactured from 1935 to 1949. 11255 pieces were made.
This lens is a derivative of the triplet lens, and the front and rear elements of the three lens groups are pasted together.
