Pentax's fast first-generation 6x7 tele — the Super-Takumar 6x7 150mm f/2.8 for portraits on 6x7.
The Super-Takumar 6x7 150mm f/2.8 is a fast short-telephoto 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 line's short-telephoto portraiture optics.
This is a manual-focus lens for the Pentax 67 bayonet mount, covering the 6x7 cm frame. It has a fixed 150mm focal length and a maximum aperture of f/2.8, fast for a medium-format telephoto. On the large negative a 150mm gives a classic portrait-telephoto reach, and this early version carries the multi-coating the Super-Takumar badge denotes.
The bright f/2.8 aperture gives strong subject separation on the big negative, throwing backgrounds well out of focus for portraits. Early Takumar 6x7 telephotos carry a warm rendering that softens slightly wide open and sharpens on stopping down, a look that suits flattering head-and-shoulders work on the large frame.
On the used market this fast early telephoto is sought by 6x7 portrait shooters and holds reasonable prices. Inspect for haze and internal fungus, check the front element for marks, and confirm the aperture blades are oil-free with a smooth helicoid. Watch for thorium yellowing as with early Takumars; it adapts to mirrorless via a Pentax 67 adapter.
