Pentax HD DA AF 1.4x AW Rear Converter
The Pentax HD DA AF 1.4x AW Rear Converter extends the focal length of
the attached Pentax lens by 1.4x, while maintaining autofocus
functionality (providing the lens has a maximum aperture of f/4.0 or
brighter) and minimum focusing distance. The Rear Converter is made with
a weather-resistant, dustproof construction for all-weather shooting and
mounts between the camera body and main lens. The converter is
compatible with the Pentax K-3, K-50, K-500, K-30, K-5 II, K-5 II s,
K-5, K-01, K-7, and K-r.
• Optical systems optimized for APS-C sensors
• Compatible with both in-lens AF (SDM,DC) and in-body AF
• Dust & Water proof constitution (AW)
• HD coating
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. The minimum focusing distance
of the main lens is retained despite the extended focal length,
providing for the capture of larger, more detailed images of the subject
in close-up shooting.
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).**
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.
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.
*When this rear converter is mounted, the lens maximum aperture will be
smaller (darker) by 1 step.
**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.
*** HD stands for High Definition.
