Long Super-Multi-Coated TAKUMARS
Super-Takumars with coated lenses that reduce internally reflected light, significantly.
Claimed to reduce internal reflections by approx. 5-8% and sold as Super-Multi-Coated lenses from 1971.
Optically, one new lens and several re-engineered versions. For example the short-lived Super-Multi-Coated TAKUMAR 1:1.9/85 (43641) made only in 5 batches in 1971 without open-aperture metering facilities was unsuitable for the new ES and SP F cameras. A solution was found by replacing it with a fast new lens with both features (see 43832).
Product numbers consisting of 5 numerals are inscribed onto aperture control switches.
