Takumar

Takumar is the name that Asahi Optical gave to its lenses, notably but not exclusively those for its own SLR cameras.

[2] The name adorned its lenses until 1975, when Asahi switched from the M42 screw mount to the bayonet K-mount.

K-mount lenses were simply named "SMC Pentax".

[3] 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.

Non-Asahi cameras with Asahi lenses branded Takumar include the Suzuki Press Van and two versions of the Takane Mine Six.
