Used Pentax 645 lenses
Here you'll find used lenses with the Pentax 645 mount: glass for the medium format Pentax systems, from sharp primes to handy zooms. Whether you shoot portraits, landscapes or studio work, this section holds the optics that really make use of that larger negative or sensor area. You'll recognise them by the familiar SMC, FA and D FA designations, and by that typical Pentax look: rich colours and a calm, filmic transition to out-of-focus areas.
The range runs from the classic FA series to the more modern D FA lenses with weather-resistant construction and quiet autofocus. Popular choices are the D FA 645 90mm f/2.8 Macro, the HD Pentax-D FA 645 35mm, the SDM D FA 645 55mm and, from the FA line, the 45mm, 75mm and 150mm. Not sure about the right focal lengths?

Medium format is all about that large capture area, and the lens determines whether you get everything out of it. Pentax 645 glass is known for being solid and optically strong, and that is exactly why buying used is so attractive here: you get pro quality without the new price. The FA lenses have been loved for years for their character, while the newer D FA models bring extra weather resistance and more modern coatings.
What should you look out for with a used 645 lens?
Check the glass for fungus, small scratches and internal clumps of dust, and turn the focus ring and, where fitted, the zoom mechanism to feel whether everything runs smoothly. With autofocus lenses, it's wise to check that the AF responds quickly and quietly. A fungus-free lens with clear coatings will go on performing for years. Our lenses are professionally inspected, so you know in advance what condition your lens is in.
Who is this for?
For photographers who are making the move to medium format or want to expand their Pentax 645 system without burning through their budget. Portrait and landscape photographers get a great deal of pleasure from the primes; those who want to work flexibly choose a zoom. Every purchase comes with a minimum 12-month warranty and 14-day returns, so you can take your time testing whether the lens suits your work.
