Pentax's classic medium format 150mm portrait lens for the 6x7 system — legendary for portraiture.
The Pentax SMC 67 150mm f/2.8 is a fast medium format portrait lens designed for the Pentax 6x7 and 67 camera systems. On the 6x7 format, 150mm provides roughly the same field of view as a 75mm lens on 35mm film — the classic portrait focal length. It is widely regarded as one of the finest portrait lenses ever made in any format.
Optical performance is exceptional. Sharpness is outstanding from f/2.8 with a smooth, creamy rendering that flatters skin tones. The combination of f/2.8 speed on medium format creates extraordinarily shallow depth of field that no 35mm or digital full-frame system can replicate. Bokeh is famously beautiful — smooth, rounded, and three-dimensional.
Pentax 67 mount, designed for the Pentax 6x7 and 67/67II cameras. Filter thread is 67mm. Weight is approximately 790 grams. Build quality is superb with all-metal construction and SMC multi-coating. Manual focus only with a beautifully damped focusing ring. The lens also works on Pentax 645 systems with an adapter, though with cropping.
Highly sought after on the used market with strong prices reflecting its reputation. Check for haze, fungus, and smooth helicoid operation. Copies in excellent condition command a premium. One of the strongest arguments for shooting medium format film — the rendering this lens produces wide open is genuinely in a class of its own.
