The Pentax 18-135mm f3.5-5.6 ED AL IF DC WR Lens has been designed to be compact and lightweight despite its high zoom ratio, making it a versatile, maneuverable everyday-use lens. A simplified weather-resistant construction and an extra-smooth autofocus operation using a built-in motor, in addition to its high 7.5-times zoom ratio, allow the DA 18-135mm WR to accommodate a wide range of subjects and scenes that photographers come across in their shooting sessions — from scenic images and snapshots to portraits and sports photos
High zoom ratio When mounted on a PENTAX digital SLR camera body, this standard zoom lens offers a high zoom ratio of 7.5 times, covering the focal length range between 27.5mm wide angle and 207mm telephoto in the 35mm format. This high zoom ratio gives it the versatility to accommodate a wide range of subjects and scenes. Thanks to advanced PENTAX optics design technology, it is compact and lightweight, despite its high zoom ratio, making it a versatile, manoeuverable every day-use lens. Simplified weather-resistant construction This zoom lens features a simplified weather-resistant construction to prevent the intrusion of water and moisture. By mounting it on a weather-resistant PENTAX digital SLR camera body, the user is assured of a durable, dependable digital imaging system that performs excellently, even in the rain and wet conditions. Extra-smooth SDM autofocus operation A DC motor built into the lens’ AF (autofocus) unit assures extra-smooth autofocus operation. It features a rotation-free mechanism to keep the focus ring stationary during autofocus operation. The user can hold the lens in exactly the same way as when using it in the manual-focus mode. High-quality image detail Incorporating an ED (Extra-low Dispersion) glass element, a hybrid aspherical element and a glass-moulded aspherical element in its optics, the lens promises exceptional image detail with minimal aberrations. These elements also contribute to the downsizing of the lens body. Rounded diaphragm to produce beautiful bokeh The lens features a completely rounded diaphragm to produce a natural, beautiful bokeh (out-of-focus) effect, while minimising the streaking effect of point light sources. Other features Minimum focusing distance of 0.4 metres over the entire zoom range Quick-Shift Focus system for instant switching to manual-focus operation after the subject has been captured in focus by the AF system.
