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. Compatible Lenses
