Product Overview

Extend your reach without weighing down your kit. The Pentax DA Teleconverter 1.4x K-Mount (model 37962) slots neatly between your Pentax K-mount DSLR and compatible KAF2 lenses, boosting focal length by 1.4x while only costing you a single stop of light. Minimum focus distance stays the same, so you can keep working close while pulling distant subjects in tight – ideal for wildlife, sports and long-range landscape details.

Built for real-world Aussie conditions, this HD PENTAX-DA AF Rear Converter AW features PENTAX’s HD multi-layer lens coating for crisp, high-contrast images with reduced flare and ghosting. Its compact 20 mm length and 126 g weight make it an easy permanent resident in your bag, and the weather-resistant, dustproof construction with AW sealing keeps you shooting when the forecast turns ordinary. Autofocus and auto aperture are fully supported with both camera-driven and lens-driven AF systems, including SDM and DC lenses, provided your camera firmware is up to date. If you’re chasing more reach from your existing Pentax glass without stepping up to a bigger, heavier telephoto, this converter is the smart, no-fuss upgrade.
