As much as I have tried to look for information about this lens' manufacturer around the web, there is little to be found. The general consensus appears to be that it is very hard to determine the origins based on serial number so if anyone solves that puzzle, please post a reply. There are some Sears 28mm lenses that are thought to be of Tomioka origin and are considered to be of exceptionally high quality.
Ignoring the company of origin for the moment, the lens has a very sturdy build and a very solid feel to it.
The focus ring 'glides' around the barrel though it is not quite as damped as the Taks or the Flektogon but is a pleasure to use being different. The aperture clicks through full stops.
The image quality is fairly good. Colors are neutral and results moderately sharp wide open.
