Ricoh Imaging Enhances K-Mount Lens Lineup with Debut of Rear Converter
Autofocus Functionality and Weather-Sealing Maintained with HD PENTAX DA AF 1.4X AW Rear Converter
DENVER, CO, February 5, 2014 – Ricoh Imaging Americas Corporation (Ricoh Imaging) is pleased to announce the release of the HD PENTAX DA AF 1.4X AW rear converter. Measuring only 20 millimeters in length, the compact, lightweight HD PENTAX DA AF 1.4X AW rear converter closes the gap between the photographer and subject, enhancing the versatility of their telephoto lenses by extending the focal length by 40%.
Optimized for Ricoh Imaging’s acclaimed lineup of PENTAX K-mount lenses, the HD PENTAX DA AF 1.4X AW rear converter is the ideal product for the photographer that requires the additional flexibility accompanied by added focal length. Additionally, the HD PENTAX DA AF 1.4X AW rear converter has been engineered to maintain the autofocus (AF) functionality while working seamlessly with both camera-driven as well as lens-driven AF systems.
"The introduction of the HD PENTAX rear converter exemplifies our commitment to providing photographers with useful products and accessories that enable them to execute their creative vision," said Jim Malcolm, Executive Vice President, Ricoh Imaging. "The rear converter makes good on that promise by giving photographers the extra focal length they need to realize the image."
Composed of four elements in three groups, the HD PENTAX DA AF 1.4X AW rear converter features superior optics and incorporates the PENTAX-developed HD coating. This high-grade, multi-layer coating is designed to minimize reflectance inside the converter while optimizing light transmittance letting the user capture crisp, high-contrast images free of flare and ghosting, even under adverse backlit conditions.
Finally, thanks to its three airtight seals, photographers can combine Ricoh Imaging’s lineup of PENTAX weather-resistant, dustproof DSLRs and lenses to assemble a dependable digital imaging system that performs superbly even under harsh outdoor conditions.
Pricing and Availability
The HD PENTAX DA AF 1.4X AW rear converter will be available at retailers nationwide and online in March 2014 for a price of $599.95.
1. 1.4-times focal length extension
By mounting this rear converter between the camera body and main lens, the user can extend the focal length 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 subjects in close-up shooting.
*When this rear converter is mounted, the lens maximum aperture will be smaller (darker) by 1 step.
2. AF compatibility Maintained
When coupled with an AF lens, the autofocus operation can be performed. 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.
3. 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.
4. 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 master lens. The application of PENTAX-developed HD coating*** — a high-grade, multi-layer coating designed to minimize reflectance inside the converter while optimizing light transmittance — lets the user capture crisp, high-contrast images free of flare and ghost images, even under such adverse lighting conditions as backlight.
*** HD stands for High Definition.
