Canon 300/4 R

The 300/4 Canon R was the shortest of the long lenses produced for the Canonflex system that used the Bellows R to focus. It was also the longest of the lenses to have a fitted leather case. It appears that the only difference between this and the version for the rangefinder is that the rangefinder version uses the Intermediate Tube, and the Canonflex lenses use the Intermediate Tube R, which probably compensate for the differences between the thickness of a Canonflex body compared to a Canon 7 or 7s and the Mirror Box 2. The diaphragm is manual. It was introduced in January 1960, and was constructed of five elements in four groups, stopped down to f/22 and accepted 48mm filters via a holder in the rear section of the barrel. Minimum focus was just under 60 inches.

The price in March 1962 was $321.00.
