Pentax's fastest 6x7 normal — the Super-Takumar 6x7 105mm f/2.4, prized for portrait rendering.
The Super-Takumar 6x7 105mm f/2.4 is the fast standard lens from the first generation of Pentax 6x7 glass, released with the camera in 1969. The Super-Takumar 6x7 badge marks it as an early example, before the SMC Pentax 6x7 and SMC Pentax 67 rebrandings of the same 105mm design that followed over the system's long life.
This is a manual-focus lens for the Pentax 67 bayonet mount, covering the 6x7 cm frame. It has a fixed 105mm focal length and a maximum aperture of f/2.4, the fastest aperture in the whole 6x7 line. On the large negative the 105mm is the normal lens, and this early Super-Takumar version carries the multi-coating the badge denotes.
The 105mm f/2.4 is the lens most associated with the Pentax 6x7 look, prized for smooth out-of-focus rendering and gentle subject separation on the big negative. Wide open it is soft and glowing, firming up as it stops down, a combination portrait shooters have long chosen for its rounded, flattering backgrounds.
On the used market this early version is in strong demand and holds high prices among 6x7 portrait shooters. Inspect for haze and internal fungus, check the front element, and confirm the aperture blades are oil-free with a smooth helicoid. Watch for thorium yellowing as with early Takumars, and note it adapts to mirrorless via a Pentax 67 adapter for its rendering on digital.
