The above lens is an U.C. (Ultra Compact) version of its `big brother the 180mm f2.8 lens. It’s unique combination of apochromatic design and macro capabilities produces a lens of excellent optical performance from infinity to minimum focusing distance of 55cm (1:2 reproduction ratio).

The lens has an internal focusing system with both 2nd and 3rd group lenses floating which makes for an extremely compact lens.
