{{ :lens:pentax600mm6x7.png?350|}}
==== Summary ====
The S-M-C Takumar 6×7 / Takumar 6×7 600mm f/4 is a legendary ultra-telephoto prime introduced in 1969 for the Pentax 6×7 system, with a second version released in 1971 featuring Super-Multi-Coating (SMC). Optically identical across both versions, it employs a 6-element, 5-group design with a manual 12-blade diaphragm, stopping down to f/45. With a diagonal field of view of just 8.5°, it’s equivalent to a 300mm lens on full-frame, making it ideal for wildlife, sports, and long-distance landscape work. The lens focuses down to 12 meters, has no internal focusing, and uses rear-mounted 77mm filters. It mounts via the outer bayonet, includes a built-in slide-out hood, and weighs a staggering 6kg, measuring 170 × 370mm—a true behemoth in the Pentax 6×7 lineup.\\
