I found this very good condition 1979-vintage SOLIGOR 28mm f2.8 (SN 4793243) lens at a thrift store ($8) Paired it with my Samsung NX1 digital camera using a M42-to-NX adapter, set the camera to manual and headed-out to do some street photography downtown Phoenix about 1-hour before sunset. All images straight from camera sensor. All in-camera effects off and no 'post' manipulation.
First photo I call the new look of Phoenix. Wow! Right from the first image, this lens produces images with subtle color tones that are very pleasing to the eye.

ABOUT SUN OPTICAL
In the 1950s or 1960s, the company was using the English name Sun Optical Co., an independent Japanese lens maker wbased in the city of Ichikawa (in the Chiba Prefecture, at the East of Tokyo).
The company began as Kajiro Kōgaku Kenkyūjo in 1939 selling lenses under the K.O.L name and then renamed to Gojō Kōki in 1941.
The company ended in 1945 but was soon revived as Sun Kōki, selling lenses under the Sun name with "Sun Opt" or "Sun Optical" often appearing on lenses. Sun made many lenses under their own name as well as producing products under contract for other companies such as Soligor.
In the late 70's or possibly early 80's the company became 'Gotō Sun' and continued to sell lenses until some time in the late 80's when they appear to have been absorbed by Goyō Kōgaku Shōji also know as Goyo Optical.
I photograph the changing urban landscape here in Phoenix. In the photo below, I like how this lens along with the camera produce a subtle (low contrast) shade, then transition to bright light.
