Description
The Pentax SMC-DA 20-40mm F2.8-4 HD ED Limited Silver has two times optical zoom and a maximum aperture of F2.8 at wide angle mode. In addition to an HD-coating and a completely round aperture, this lens has a weather-resistant construction. Together with the silent auto-focus system driven by an autofocus motor, this lens creates beautiful images under poor weather conditions.
The Pentax DA 20-40mm F2.8-4 HD ED Limited DC WR offers a focal length of 30.5 mm to 61.5 mm (on a 35mm camera) when used on a digital camera body with interchangeable lens from the Pentax K-series. The versatility of the range, the large aperture, and weatherproof housing makes it ideal for everyday use.

Limited Lens series for crisp, clear images
The design of this lens is a legacy of the Limited Lens series. The lens has an optical system that faithfully reflects the depth and simultaneously minimizes distortion at the corners in the entire zoom range. Photographers optimize the image of their subject by softening its appearance at a larger aperture and make it sharper with a smaller aperture. The lens cylinder, hood and cap are made of high-quality aluminum material and processed by hand for a perfect size and a nice texture. The zoom ring is in the middle of the lens cylinder and has a number of serrated grooves in order to make the zoom operation easier.
High-quality optics
The lens is treated with the HD coating developed by Pentax, a high-quality coating with multiple layers. This reduces reflection in the visible light spectrum with more than fifty percent, in comparison with traditional multilayer coatings. This allows the user to capture sharp, high contrast images without flare and ghosting, even under adverse lighting conditions like backlight. The lens also features an ED glass element (Extra-low Dispersion) and a super-low dispersion glass element for crisp high-resolution images with one hundred percent focus. It also effectively compensates colour aberration throughout the entire zoom range.
The first weather-resistant lens in the Limited Lens series
This lens is the first model in the Limited Lens series with a weather-resistant construction, with seven special seals to protect the lens interior from water and moisture. Put the lens on a weather-resistant digital SLR camera body from Pentax and the user is assured of greater durability and reliability during shooting in rain or mist and at locations with a risk of spraying or splashing water.
