Standard SMC lens for Pentax 67 medium format — the essential 6x7 normal perspective.
The Pentax SMC 67 135mm f/4 is a standard lens for the Pentax 67 medium format SLR system, equivalent to approximately a 65mm lens on 35mm format. On the enormous 6x7cm negative format, this focal length provides a natural perspective that makes it the go-to lens for general and portrait photography on the Pentax 67.
Optical quality is excellent with the SMC coating delivering rich contrast and accurate colour rendition on the generous 6x7cm negative. The four-element design is sharp across the frame at moderate apertures, and the medium format negative size ensures extraordinary detail and tonal depth from every frame exposed.
Build quality is robust metal construction designed for the substantial Pentax 67 system. The focus ring is smooth and precise, and the aperture ring clicks positively at each setting. The lens is relatively compact for a medium format optic, keeping the already large Pentax 67 system as manageable as possible.
On the used market, the SMC 67 135mm f/4 is the standard lens every Pentax 67 owner should have. For medium format photographers using the 67 system for portrait, landscape, and general work, it provides the natural perspective and excellent optical quality that makes the 6x7 format so rewarding.
