Lens Overview — Pentax 75mm f/2.8 SMC FA
Key Features — Pentax 75mm f/2.8 SMC FA
75mm Standard Focal Length: Equivalent to roughly 60mm in full-frame terms on the Pentax 645 system, making it a natural fit for portraits, street, and general-purpose shooting.
f/2.8 Maximum Aperture: Fast aperture for a medium format prime, allowing for subject separation and usable performance in lower light conditions.
Pentax 645 Mount: Natively compatible with Pentax 645 film and digital medium format bodies, including the 645D and 645Z.
Autofocus with Manual Override: Supports both AF and MF operation, giving photographers flexibility depending on the shooting situation.
SMC Coating: Pentax's Super-Multi-Coating reduces flare and ghosting for cleaner contrast and color rendition.
Lightweight at 215g: Unusually light for a medium format lens, reducing fatigue during extended handheld or travel shoots.

Description — Pentax 75mm f/2.8 SMC FA
The Pentax 645 75mm f/2.8 SMC FA is a prime lens built for the Pentax 645 medium format camera system. It features a 75mm focal length — sitting squarely in the standard range for medium format — paired with a f/2.8 maximum aperture that provides meaningful light-gathering capability. The lens supports both autofocus and manual focus, offering flexibility for different shooting styles and situations.
Weighing just 215 grams, it punches well below the weight expectations for a medium format lens, making it a comfortable companion for longer shoots. The 67mm filter thread allows easy use of widely available filters. One practical consideration is the absence of image stabilization, so steadying techniques or support equipment may be needed in challenging lighting.
The lens mounts exclusively to cameras with a Pentax 645 mount, making it a dedicated tool for that system.
