Description — Pentax 75mm f/2.8 SMC A
The Pentax 645 75mm f/2.8 SMC A Lens is a prime lens purpose-built for the Pentax 645 medium format camera system. With a 75mm focal length sitting in the standard range, it delivers a natural perspective well-suited to a broad range of photographic applications. The f/2.8 maximum aperture gives photographers a bright, capable opening for controlling depth of field and managing available light.
At just 230g, this lens punches above its weight in terms of portability — it is a genuinely compact option within the medium format world. A 67mm filter thread provides easy compatibility with a wide variety of filter accessories. Focus is manual only, making it best suited to deliberate, considered shooting styles.
There is no image stabilization built into the lens. Mounted on the Pentax 645 lens mount, it integrates directly and reliably with compatible Pentax 645 bodies, making it a practical standard prime for photographers already shooting within that system.
