Pentax's 67-era fast normal — the SMC Pentax 67 105mm f/2.4, the classic 6x7 portrait lens.
The SMC Pentax 67 105mm f/2.4 is the later-branded version of Pentax's fast standard lens for the 6x7 medium-format system. It carries the SMC Pentax 67 name used from around 1989, the third generation of the line after the Super-Takumar 6x7 and SMC Pentax 6x7 labels, continuing the same 105mm normal-lens role on the 6x7 frame.
This is a manual-focus lens for the Pentax 67 bayonet mount, covering the 6x7 cm negative. It has a fixed 105mm focal length and a maximum aperture of f/2.4, the fastest in the line. On the large frame the 105mm is the standard lens, and the Super Multi Coating denoted by the SMC prefix controls flare and internal reflections.
The 105mm f/2.4 is the lens most tied to the Pentax 6x7 signature, known for smooth background rendering and subject separation on the big negative. It renders softly wide open and sharpens as it stops down, a look portrait photographers seek out, and this later version is the one many current users buy for that character.
On the used market this 67-branded 105mm is popular and holds its value, being the most current version of the classic portrait lens. Check the elements for haze and cleaning marks, look for fungus, and confirm the aperture blades are dry with a smooth focus action. It adapts to mirrorless through a Pentax 67 mount adapter for the rendering on digital bodies.
