Pentax's first-generation 6x7 wide-standard — the Super-Takumar 6x7 75mm f/4.5 for the 6x7 negative.
The Super-Takumar 6x7 75mm f/4.5 is a wide-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, predating the SMC Pentax 6x7 and SMC Pentax 67 names that later branded lenses at this focal length.
This is a manual-focus lens for the Pentax 67 bayonet mount, covering the 6x7 cm frame. It has a fixed 75mm focal length and a maximum aperture of f/4.5. On the large medium-format negative a 75mm gives a mildly wide to near-standard field of view, and the multi-coated Super-Takumar glass was designed to cover the big image circle.
The lens carries the warm rendering associated with early Takumar 6x7 optics, gaining crispness as it stops down. Its angle of view suits landscapes, street and general everyday shooting on the 6x7 frame, and the compact design makes it a lighter alternative to the faster wide-standard options in the line.
On the used market this early wide-standard is an affordable period piece for 6x7 shooters. Inspect for haze and internal fungus, check the front element for cleaning marks, and confirm the aperture blades are oil-free with a smooth helicoid. Look for any thorium yellowing as with early Takumars, and note it adapts to mirrorless via a Pentax 67 adapter.
