Later, in 1971 the line-up was improved by implementing the multi coating and extended with new lenses: 90 with leaf shutter, 135 Macro, 500 and 1000. In the late 70's and early 80's the line-up was updated again with some cosmetic changes.

Lenses with 67mm and 82mm filter threads accept screw-in and 6X7 bayonet filters, excluding new 75mm f/2.8 AL. It has no bayonet notches in the filter thread and thus it accepts only 67mm screw-in filters. In the other hand only 55mm f/4 (I) with 77mm filter thread accepts both filter types, while the other lenses with the same thread accept only screw-in filters. There are three other lenses accepting 77mm rear mounted filters of the both types: 400, 600 and 800.


Most lenses made for the camera's inner bayonet mount. Only four lenses were made for the outer bayonet: 400, 600, 800 and 1000 Mirror. Also these lenses have fully manual aperture while mirror lens has no aperture at all. Another two lenses with manual apertue made for the inner bayonet: 75mm f/4.5 Shift and 120mm f/3.5 Soft. The last one rather is a standard lens than a portrait lens. It has 41° field of view that is really closer to 46° of 105mm f/2.4 standard lens.
