1970 Vivitar lenses test
These are the fixed mount lenses in the Kino Precision all-black series (serial numbers beginning 22). The exception is one "bright band" 135/3.5 telephoto (serial number beginning 40).
As the 135mm tests note, plain resolution numbers do not tell a complete story. Still we can see that at middle apertures these are respectable results, if not quite at the level of premium first-party lenses.
