Pentax 67 SMC Takumar 135mm f/4
Summary
The SMC Pentax 67 / S-M-C Macro Takumar 6×7 135mm f/4 is a manual-focus close-up lens introduced in 1971 for the Pentax 6×7 medium format system, with a cosmetically updated version released in 1989 under the “67” branding. Despite the “Macro” label, it offers a maximum magnification of 0.31×, making it more of a close-focusing telephoto than a true macro lens. Both versions share the same 5-element, 3-group optical design and are known for their Heliar-inspired rendering, with excellent sharpness and smooth bokeh. The lens stops down to f/32, focuses as close as 75cm, and uses a 67mm filter thread. It weighs around 620–645g, measures 91.5 × 95mm, and includes an 8-blade automatic diaphragm. There’s no internal focusing or “A” setting on the aperture ring, so metering is manual or stop-down only. The front element is deeply recessed, reducing the need for a hood, though a PH-SA67 clip-on hood was available. It was typically supplied with the S90-140 soft case and metal push-on cap.
Came in two variants with similar specs:
Super-Multi-Coated Takumar 6×7 135mm f/4 Macro in 1971; SMC Pentax 67 135mm f/4 Macro in 1989
