T a k u m a r 1 : 3.5 f = 50 mm Model III
Produced 1954 to 1957. Serial Numbers 475xx - 945xx. For Asahiflex IIB and IIA. Updated Jan. 2026.
(Research Note: Since 2020 I have seen 1.72% (270 copies) of the total estimated 15,600 copies made.)
INTRODUCTION
The standard lens for the ASAHIFLEX IIA and IIB. or the TOWER 22,23 and 24.
This third version of the standard 1:3.5/ 50mm Takumar coated lens soon came into competition with the longer focal length 1:24 58mm Takumar. This gave customers a choice and allowed Asahi Optical Co. to search for optimal focal lengths for a standard lens.

DESCRIPTION
The colours of the nameplate and the lettering on this version have been reversed making it easier to identify.
Distance scale units are in either "Meter" or "Feet". Copies of the former make up < 20% of the total. The latter copies were made principally for export to North America.
