Ricoh has announced the HD Pentax-D FA 70–210mm F4 ED SDM WR, a new telephoto zoom lens for its full-frame K-mount DSLR camera systems.

The lens, which strongly resembles the Tamron 70-210mm F4 Di VC USD, is constructed of 20 elements in 14 groups, including three extra-low dispersion (ED) elements and two anomalous dispersion elements. It features a minimum focusing distance of 95cm (3.1ft), a nine-blade aperture diaphragm, uses Pentax’s high-definition (HD) multi-layer coating on its elements and features a weather-resistant design that works alongside Pentax’s weather-resistant DSLR cameras to provide a tight seal against the elements.

Powering the autofocus is a ring-type supersonic direct-drive motor (SDM) and a quick-shift focus system makes it easy to switch from autofocus to manual after the shutter has been half-pressed. The lens measures in at 175mm (6.9in) long, 78.5mm (3.1") diameter and weighs 859g (1.89lbs) with the lens hood on.

The HD Pentax-D FA 70–210mm F4 ED SDM WR will be available starting February 15, 2020 for an MSRP of $1,100.

Ricoh announces compact, lightweight, high-performance telephoto zoom lens for use with 35mm full-frame digital SLR cameras

New HD PENTAX-D FA 70–210mm F4 ED SDM WR provides great portability in a variety of applications, from nature and scenic photography to active fieldwork

PARSIPPANY, NJ, January 22, 2020 - Ricoh Imaging Americas Corporation today announced the HD PENTAX-D FA 70–210mmF4ED SDM WR zoom lens for use with PENTAX K-mount digital SLR cameras. This high-performance telephoto zoom lens features a compact, lightweight body with weather-resistant construction for great portability in a variety of outdoor applications.

Featuring a highly portable design, this high-performance zoom lens covers the image circle of 35mm full-frame digital SLRs, and provides a focal length range of 70mm to 210mm ideal for handheld outdoor photography. A constant f/4 maximum aperture ensures consistent brightness throughout the zoom range and enables increased control over depth of field for selective focus effects. When used with an APS-C-format camera, its focal length range is extended to the equivalent of 107mm to 322mm in the 35mm format. The new lens has a minimum focusing distance of 0.95 meters and a maximum magnification of 0.32 times, providing greater macro coverage than previous models. It also features a Quick-Shift Focus System that enables an instant shift to manual-focus operation after locking a subject in focus during autofocus operation.

This lens is ideal for active field photography in a wide range of outdoor applications including scenic photography, landscape shooting with a beautiful bokeh effect in the fore- and background, close-up photography of animals and plants, and sports and wildlife photography where its outstanding portability really comes in handy.

A high-grade, multi-layer high-definition (HD) coating has been applied to the optical elements of the lens, enabling the capture of high-contrast images with edge-to-edge sharpness and minimizing flare and ghost images. A super-protective (SP) coating, highly repellent to water, grease and dirt, has also been applied to the lens’ front surface, making it easy to wipe off stains or fingerprints.
