The Vivitar 28mm f/2.8 Wide-Angle T-4 mount lens was marketed by Ponder and Best (Vivitar) in the late 1960s. It was part of a family of T-4 mount lenses. The T-4 mount could be adapted to most commonly used camera mounts of the era. A lens review in the February/March 1969 issue of Camera 35 magazine notes the similarity of the Vivitar T-4 family to the Soligor T-4 lenses. It is believed both the Vivitar and Soligor T-4 lenses were designed by Tokina with slight customizations made to the specifications of each company. The review had this to say about the 28mm:

The performance is impressive. Following today's wideangle lens design approach, it is a retrofocus seven element lens. Working with it is easy since it's both light and fairly compact. Tests show some slight vignetting which clears up completely at f/5.6. Contrast also improves at f/5.6-f/8, the two optimum apertures.[1]
