The Pentax SMC DA 18-270mm F3.5-6.3 SDM Lens For K Mount [21497] is an all-encompassing zoom lens, featuring a 15x zoom range from a wide 18mm to a long 270mm (equivalent to 27.5-414mm in 35mm format).

This high-magnification zoom lens offers 15-times zoom ratio to cover focal lengths from wide angle to super telephoto, while its built-in supersonic AF driving mechanism achieves both smooth, quiet AF operation and a compact, lightweight body. Its extraordinary wide angle-to-long-telephoto zoom coverage makes this zoom lens extremely versatile and handy, as it allows the user to effortlessly capture a wide variety of subjects, ranging from landscapes and snapshots to sports events, without the need of lens changes.

Benefitting the long reach of this lens, two extra-low dispersion elements have been incorporated into the lens construction to help reduce chromatic aberration and improve overall image clarity. A minimum focus distance of 1.6' across the entire zoom range also makes this lens an effective tool for macro and close-up work.

The SDM autofocus system has also been integrated into the design, which utilizes a supersonic motor for fast, quiet autofocus operation. The lens also features a rounded 7-blade diaphragm for smooth out of focus regions and less susceptibility to highlight streaking.

Specifically designed for use with Pentax K-mount DLSR cameras.

15-times zoom covering the extra wide range.

When mounted on a Pentax K-mount lens-interchangeable digital camera body, this zoom lens offers an 15-times zoom ratio covering focal lengths from 27.5mm wide angle to 414mm super telephoto in the 35mm format. This allows the photographer to capture a wide range of scenes and subjects without lens changes — ranging from such casual applications as scenery, snapshot and portraiture to long-range sports photography. Its newly designed optics is the key to achieving such wide zoom coverage in a compact, lightweight body, for optimal versatility and maneuverability.

Supersonic AF motor (SDM)

Thanks to the incorporation of the Pentax-original SDM autofocus system driven by a built-in supersonic motor, this zoom lens offers exceptionally smooth and quiet autofocus operation. When mounted on an SDM-compatible Pentax K-mount lens-interchangeable digital camera body,* the focus mode is automatically switched to SDM-assisted autofocusing to ensure dependable, flawless AF operation.
** This lens is compatible with the K-5 II, K-5 II s, K-30, K-01, K-5, K-r, K-7, K-x, K-m, K20D, K200D, K100D Super and K10D camera bodies (with Ver. 1.30 or later firmware installed). When mounted on other camera bodies, the focus mode is automatically switched to manual.
