This superb little lens is ideal for use on any RZ67 camera with lenses of 110mm and longer. Multiplies the focal length of your lens by a factor of 1.4, with the loss of one stop of exposure – your 110mm f2.8 becomes a 154mm f4.0.
This lens is in mint condition with absolutely minimal signs of use; a really clean example and supplied with both end caps.
