Deal of the day: the HD Pentax DA 20-40mm f/2.8-4 ED Limited DC WR lens is now $300 off

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.

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.

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

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

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.

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.

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.

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