Used Pentax K lenses

The Pentax K mount is a rewarding system to shop used, precisely because older and newer lenses largely continue to understand each other. An FA prime from a few generations back still performs perfectly well on a modern Pentax body, and that keeps the range broad and the prices reasonable. Pentax traditionally builds sturdy lenses, so well-maintained examples last a long time. If you want to buy something now, the Pentax SMC Pentax-DA 18-135mm f/3.5-5.6 ED AL DC WR is a much sought-after all-rounder, complemented by the Pentax HD Pentax-DA 55-300mm f/4.5-6.3 ED PLM WR for telephoto work and the Pentax HD Pentax-D FA 24-70mm f/2.8 ED SDM WR as a weather-resistant standard zoom.

What to look out for with a used Pentax K lens

Check the glass for fungus, scratches and dust, and turn the zoom and focus rings to feel whether everything runs smoothly. With autofocus lenses that have an SDM or DC motor, you want to know whether the focus locks on quickly and quietly; older screw-driven (AF coupling) lenses only work briskly on bodies with an internal motor. With weather-resistant WR and AW models, pay attention to the condition of the seals. With us, every lens is professionally inspected and tested, so you know what you're bringing home.
