Pentax 150mm f/3.5 smc PENTAX-A 645 Manual Lens for Pentax 645, Black Review

The Pentax 150mm f/3.5 smc PENTAX-A 645 is a manual focus medium format lens designed for the Pentax 645 film system. With its moderate telephoto focal length and built-in hood, it delivers a field of view roughly equivalent to 95mm in full-frame terms, making it a solid choice for portraiture and detail work on the 645 platform. The smc (Super Multi Coated) optical treatment was Pentax's standard for minimizing flare and boosting contrast during the film era.

This is a legacy manual lens, so autofocus and electronic communication with modern bodies are off the table. It's best suited to photographers already invested in the Pentax 645 ecosystem or those who enjoy the deliberate pace of manual focus shooting on medium format. At this price point, it represents accessible entry into medium format telephoto work, though availability is limited to the used market and condition can vary.
