Canon 135/3.5 R
The 135/3.5 Canon R was offered as a less expensive alternative to the 135/2.5. Aside from being
slower, it also has a manual diphragm. It is a four element, three group construction stopping down to
f/22 using 10 diaphragm blades. The closest focusing distance is 59 inches. It uses 48mm filters. It was
produced in two versions (according to the Canon Museum website), but other than a slight difference
in weight it is unclear what the differences are. The fist version was released in May 1959 and the
second in July 1961.
The price in March 1962 was $139.95.
