The As-specified semifield of view is 26.83 deg, or 53.66deg full-field of view. Earlier I was moving between classes and rounded to 26 degrees mentally. From the mapping function, this is equivalent to a 42.874mm lens for the 24x36mm image format.
From MIR the 55/1.2 asph was released in 1971. http://www.mir.com.my/rb/photography/com...50mmfd.htm
The 12/1.2 asph hit the market in 1956, 15 years prior. The 12/1.2 was marketed as a cinema lens but saw wide utilization in other uses e.g military and photo due to its very high speed and relatively "wide" field of view. At release it was the widest navitar available and the fastest by 1/2 stop.
