Matched supplementary lens for Cosina 100mm macro lens. When attached, this takes the lens from a maximum magnification of half life size, to life size (1:1). I also have two of these lenses for auction.

This is not a simple lens, but a corrected doublet. The size is 49mm filter size, and would fit any lens with this size, but is matched in terms of performance with the Cosina.

In good clean condition.
