HD Pentax-DA AF Rear Converter 1.4X AW
Incorporating main lens AF operation, with a weather-resistant, dustproof construction
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 20mm in length, its compact, lightweight design allows users easier reach to distant subjects. The minimum focusing distance of the main lens is retained, despite the extended focal length, allowing for the capture of larger, more detailed images of the subject in close-up shooting.
*When this rear converter is mounted, the lens maximum aperture will be smaller (darker) by 1 step.
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).**
**The camera’s firmware must be updated to the latest version before using the autofocus function. Compatible camera bodies are: K-3, K-50, K-500,K-30, K-5 II, K-5 II s, K-5, K-01, K-7, and K-r. Autofocus is possible with a PENTAX lens having maximum aperture of f/4 or brighter.
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, including rain, dust and sand.
Exceptional optical performance
With its state-of-the-art optical design, this rear converter promises exceptional optical performance to optimise the potential of the main lens. With the application of PENTAX-developed HD coating*** — a high-grade, multi-layer coating designed to minimise reflectance inside the lens while optimising light transmittance — it lets the user capture crisp, high-contrast images free from flare and ghost images, even under adverse lighting conditions like backlight.
