Essential Pentax 645 telephoto zoom, constant f/4.5 covering 50-100mm equivalent for portraits and events.

The Pentax SMC Pentax-A 645 80-160mm f/4.5 is a telephoto zoom for the Pentax 645 medium format system, covering a range equivalent to approximately 50-100mm on 35mm film. This makes it a standard-to-portrait zoom that handles the most commonly needed focal lengths for medium format portrait, event, and general photography.

The constant f/4.5 aperture maintains consistent exposure and viewfinder brightness across the zoom range, a practical advantage over variable-aperture designs. Super Multi Coating ensures clean contrast and accurate colours throughout, and the optical quality is strong across the frame at all focal lengths when stopped down to working apertures.

Build quality is robust all-metal construction with a smooth, well-damped zoom mechanism and precise focusing ring. The A-series designation enables compatibility with the Pentax 645's programmed and aperture-priority exposure modes. The lens balances well on 645 bodies despite the additional weight of the zoom optics.

The 80-160mm f/4.5 is the essential zoom lens for the Pentax 645 system, covering the most frequently used focal length range in a single optic. On the used market it offers excellent value for 645 shooters who want zoom versatility without carrying multiple primes, delivering medium format quality across a practical range.
