Vivitar 100mm f3.5 Macro lens, KA Mount (PKA). This sale includes the matched 1:1 adapter, which will be added to the photos when I take my next batch of photos (I've only just found it). This is known to be a very good performer optically, despite relatively cheap construction. In good condition, with no obvious signs of fungus. Diaphragm is snappy. Focusing is acceptable, although lacking the smoothness of better made lenses.
