Pentax 80-160mm f/4.5 smc PENTAX-A 645 ZOOM Manual Lens for Pentax 645, Black Review

The Pentax 80-160mm f/4.5 smc PENTAX-A 645 is a manual zoom lens designed for the Pentax 645 medium format system. At just over two pounds, it offers a practical focal range for portrait, event, and general telephoto work without the bulk typical of medium format glass. The constant f/4.5 maximum aperture throughout the zoom range provides consistent exposure and light gathering, a useful feature for film shooters who need predictable metering.

This is a legacy manual-focus lens, which means it lacks autofocus and modern coatings but benefits from Pentax's SMC (Super Multi-Coated) optics to reduce flare and improve contrast. It's primarily available on the used market, often in good to excellent condition. For shooters invested in the Pentax 645 ecosystem looking for a versatile zoom without breaking the bank or carrying heavy primes, this lens fills a practical gap. It's not a speed demon, but it's designed for deliberate, methodical shooting where weight and flexibility matter.
