Pentax has announced the HD Pentax-DA 560mm f/5.6 ED AW, a telephoto lens that produces the 35mm focal length equivalent of an 859mm lens on a Pentax DSLR.

Pentax claims that this lens’s telescope-like design, which means it requires fewer optical elements than conventional lenses, plus its inclusion of two ED (extra-low dispersion) optical elements enable it to deliver sharper, better-defined images than other lenses.

To compliment Pentax’s weather-resistant cameras, such as the K-30, K-5 II and K-5IIs, this new lens has a weather-resistant construction with 29 seals.

In addition, the lens has a white livery to minimise the heat haze that can develop inside optics under strong sunlight.

This lens is treated with HD Coating*, a new high-grade multi-layer lens coating developed by PENTAX. Compared with conventional multi-layer coatings, it provides increased light transmittance with reduced reflection, to deliver sharp, clear images free from flare and ghost images, even under demanding lighting conditions.

This lens comes with a built-in, removable filter holder in the barrel. By mounting the C-PL (circular polarising) filter (40.5mm in diameter; included as an exclusive accessory) to the holder, the user can easily obtain the desired polarising effect simply by rotating the filter with its control ring.

The price and availability of the HD Pentax-DA 560mm f/5.6 ED AW has yet to be announced, but the Pentax-DA 18-270mm will be available from early November and is set to retail for £699.99.
