The Konica Hexanon AR 100 mm f/2.8 is a fast telephoto lens for SLR cameras with the Konica AR bayonet mount.
It came in two variants with the same optical scheme. The early variant came in an all-metal frame (it was borrowed from the Konica F bayonet mount). The subsequent variant has a rubber-coated focusing ring, and the frame design was slightly changed. Besides the later variant has enhanced lens coatings.
The Konica Hexanon AR 100 mm f/ 2.8 produces a rather good picture even for today, good resolution across the frame, rather high contrast, and almost no distortion. When wide open, the picture is flexible in a portrait way and has a soft beautiful bokeh.
The lens is not well resistant to back and side light (the later variant is better). It is recommended to use it with a hood.
The Konica Hexanon AR 100 mm f/ 2.8 showed oneself to good advantage as a portrait lens, as well as for artistic photography with shallow depth of field.
Because of a small flange focal distance it is difficult to use the Konica Hexanon AR 85 mm f/ 1.8 f/ 1.8 on modern digital SLR cameras(bayonet modification required), but it can be easily used on mirrorless cameras.
