HD Pentax DA 20-40mm f/2.8-4 ED Limited DC WR Lens in detail

The silver HD Pentax DA 20-40mm f/2.8-4 ED Limited DC WR Lens from Pentax is a high performance standard length zoom lens for K-mount APS-C camera s. Its 35mm focal length equivalency is 30.5-61.5mm providing a versatile and practical range for wide-angle to standard length shooting. It is the first zoom lens in the Pentax Limited Series line and brings with it a durable, weather-sealed body, HD lens coating and an optical design consisting of one ED element and one super-low dispersion element.

The f/2.8-4 maximum aperture enables effective low light shooting and, at the wide-angle end, control over its shallow depth of field for images that place sharp focus on the subject with a pleasing out of focus background. An in-lens direct current (DC) focus motor provides smooth and quiet autofocus action and its Quick-Shift Focus System enables rapid shift from autofocus to manual focus mode.

The lens barrel and the included hood are made from high-grade aluminum alloy, distance and depth of field scales are clearly marked on the barrel and a smooth rotating, knurled ring provides manual focus control. SP (Super Protect) coating on the front and rear lens elements repels dust, water and grease to help maintain peak performance.

30.5 to 61.5mm Focal Length Equivalency and f/2.8 Maximum Aperture

With its 2x zoom coverage of 20-40mm, this lens offers focal length coverage from 30.5 to 61.5mm in the 35mm format when mounted on a PENTAX K-series DSLR. This covers a practical set of frequently used focal lengths and is ideal as a versatile everyday lens. Its maximum aperture of f/2.8 at the wide-angle end of the zoom is effective in low light and provides shallow depth of field focus.

HD Lens Coating

This lens has been treated with the PENTAX-developed HD coating, a high grade, multi-layer coating that reduces unwanted reflection, allowing the user to capture high-contrast images free of flare and ghosting.

DC Autofocus Motor

Shoot discreetly with in-lens, direct current (DC) Auto Focus motor operation for smooth & quiet performance.

Quick-Shift Focus System

The Quick-Shift Focus System allows instant switching from autofocus to manual focus operation.

Weather-Resistant Construction and Durable Aluminum Barrel

With seven special seals to prevent intrusion of water, moisture and dust, this is the first lens of the "Limited" series to feature the PENTAX-original weather-resistant construction. With a handsome and durable aluminum alloy barrel and weather-sealing, this lens is able to perform in almost any shooting condition.

SP Lens Coating

The PENTAX SP (Super Protect) coating on the front and rear lens elements repels dust, water and grease to keep your lens clean and your images sharp.

Optical Design

The ED (Extra-low Dispersion) glass and a super-low dispersion glass element in this lens' optics deliver clear, high resolution imagery with edge-to-edge sharpness, throughout the entire zoom range.

Rounded Diaphragm Blades

Enhanced with a rounded nine-blade diaphragm at the wide apertures for optimal optical performance and gorgeous bokeh effects.
