46mm screw on glass macro lens. Comes with 46mm F to 67mm M threaded adapter.

Very low chromatic abortion or fringing. High +8 magnification. These are a economical and good quality lens for use to shoot small subjects. Can be stacked together or used in front of the +5 or +16 versions.

Note: these say UCL-05 but are the exact same lens as FIT, just OEM.
