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. The 45, 75 Shift, 120, 165, 400 ED, and 800 ED lenses were added while 55 and 90 completly updated to new versions. In the late 80's was the last cosmetic update while 55 completly updated to new version again. In the late 90's and 2001, Asahi added a last four lenses to the line including the new 75 AL, 55-100, 90-180, and 300 ED.

Filters

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.

Specific

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.
