Ricoh has announced the HD Pentax DA AF 1.4X AW rear converter, optimized for Pentax K-mount lenses.
The tele converter has been engineered to maintain the autofocus (AF) functionality while working with both camera-driven as well as lens-driven AF systems.
Composed of four elements in three groups, the converter features superior optics and incorporates the Pentax-developed HD coating, says the company. 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.
With three airtight seals, it will work with Pentax weather-resistant, dustproof DSLRs and lenses under harsh outdoor conditions.
The HD Pentax DA AF 1.4X AW rear converter will be available in March for $599.99.
