Overview

The Kiron MC 28mm f/2 is a well-constructed manual focus lens, though some copies suffer from oil on aperture blades. Optically, it is soft wide open but improves significantly when stopped down; at f/4 it is very sharp, and corners are decent. It offers an extra stop over f/2.8 alternatives, making it useful for low light. Suitable for photographers who value speed and are willing to stop down for sharpness.
