==Details== The Takumar designation was used on lenses designed for Asahi's [[35 mm camera]]s, 6×7 cameras, and for other purposes too.<ref>Pentax Lens Series overview; http://www.pentaxforums.com/lensreviews/</ref> * ''Takumar'' lenses were made in M37 screwmount for the original Asahiflex cameras and continued into the M42 period. * ''{{visible anchor|Auto-Takumar}}'' lenses were a type of preset lens. The user selected an aperture then engaged a lever to energise the stopping-down mechanism. The camera would then trip this mechanism when the shutter was fired. * ''{{visible anchor|Super-Takumar}}'' lenses featured an improved form of [[anti-reflective coating|lens coating]] (to reduce [[Lens flare|flare]]) and a more sophisticated stopping-down mechanism. There was a switch on the lens to select "Auto" or "Manual" modes. In manual mode, the lens would always be in the selected aperture. In Auto mode, the lens would remain wide open (at maximum aperture) until a pin on the rear of the lens was pushed in. This pin would be automatically pushed in by the camera when the shutter was tripped. * {{anchor|Super-Multi-Coated Takumar|SMC Takumar}} ''Super-Multi-Coated'' (later ''SMC'') ''Takumar''. These lenses introduced Asahi's lens multi-coating process (to further reduce reflections and flare). They also introduced a lug on the rear of the lens which moved with the aperture selected. When used with a camera body which could read the lug, this enabled the use of open-aperture metering. Examples of such cameras are Asahi's Spotmatic F and the ES/ESII. These SMC-Takumar M42 thread mount lenses included: 15/3.5 rectilinear ultra-wide angle, 17/4 full-frame fisheye, 20/4.5, 24/3.5, 28/3.5, 35/2, 35/2.8, 50/1.4, 50/4 macro, 55/1.8, 55/2, 85/1.8, 100/4 macro, 105/2.8, 120/2.8, 135/2.5, 135/3.5, 150/4, 200/4, 300/4, 400/5.6, 500/4.5, 1000/8. Pentax resurrected the Takumar name in the 1980s and 1990s for a budget line of zoom and prime lenses that lacked the Pentax "Super Multi-Coating" anti-reflective coating that reduces lens flare. These lenses are marked "Takumar (Bayonet)" or "Takumar-F" to distinguish them from the older screw-mount Takumar lenses. Non-Asahi cameras with Asahi lenses branded Takumar include the Suzuki Press Van and two versions of the Takane Mine Six.<ref>Suzuki Press Van: ''Shōwa 10–40nen kōkoku ni miru kokusan kamera no rekishi,'' items 795–6; {{in lang|ja}} [http://www.geocities.jp/je2luz/tin120spring01.htm page on "spring cameras"].
