HD Pentax-DA AF REAR CONVERTER 1,4AW

The compact, high-performance rear converter which extends the focal length of the main lens by 1.4 times.

This compact, high-performance rear converter not only extends the focal length of the main lens by 1.4 times, but also accommodates the flawless autofocus operation of the main lens, and features a dependable weather-resistant, dustproof construction for all-weather shooting.

Exceptional optical performance

Thanks to its state-of-the-art optical design, this rear converter assures the exceptional optical performance that optimizes the potential of the main lens. With the application of PENTAX-developed HD coating - a high-grade, multi-layer coating designed to minimize reflectance inside the lens while optimizing light transmittance - it lets the user capture crisp, high-contrast images free of flare and ghost images, even under such adverse lighting conditions as backlight.

Compatible camera bodies are: K-3 Mark III, K-3II, K-3, K-5 II, K-5 II s, K-5, KF, KP, K-70, K-50, K-30, K-S2, K-S1, K-01, K-7, and K-r. K-1 Mark II and K-1*

*When this converter is mounted between a 35mm full-frame SLR camera body and a D FA-series lens, the image size is automatically cropped to the APS-C format.

1.4-times focal length extension for telephoto effect

By mounting this rear converter between the camera body and main lens, the user can extend the focal length by 1.4 times. Measuring only 20 millimeters long, its compact, lightweight design allows the user to more easily reach out to distant subjects.
*When this rear converter is mounted, the lens maximum aperture will be smaller (darker) by 1 step.

AF compatibility

The first PENTAX rear converter to provide AF compatibility
When coupled with an AF lens, the autofocus operation can be performed by the main lens. This rear converter works perfectly with both the camera-driven AF system and the lens-driven AF system (such as the SDM- and DC- series lenses).

* This is a pure teleconverter. It transfers autofocus between the camera and lens. Lenses without autofocus continue to function as manual lenses.

Weather-resistant, dustproof construction for active outdoor shooting

Equipped with three airtight seals, this model is the first PENTAX rear converter with a weather-resistant, dustproof construction. By combining it with PENTAX’s weather-resistant, dustproof camera body and lens, the user can assemble a dependable digital imaging system that performs superbly even under harsh outdoor conditions, such as in the rain or in a cloud of dust or sand.
