A high-zoom-ratio standard zoom lens, designed exclusively for PENTAX digital SLR cameras
PENTAX Imaging Systems announces the launch of a brand new lens. The smc PENTAX-DA 18-135mm F3.5-5.6ED AL[IF] DC WR features a practical 7.5-times zoom ratio.
Designed exclusively for use with PENTAX digital SLR cameras, this interchangeable standard zoom lens features a simplified weather-resistant construction and extra-smooth autofocus operation using a built-in motor. One lens to suit all needs.
What are its key features?
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.
