A broad selection of interchangeable lenses provides flexibility and performance for handling the most challenging assignments?or just for fun! For special situations, options range from the 16mm Zenitar to the renowned mirror lenses.
Mirror lenses gained popularity for their compactness and durability. Remarkably, the 500mm f/8 3M-5CA is light in weight and surprisingly easy to handle. Plus, it shares the M42 screw mount with lenses made by Pentax.
