Product Description
The smc PENTAX-DA 18-135mm F3.5-5.6 ED AL [IF] DC WR lens is designed
exclusively for use with PENTAX digital SLR cameras. This interchangeable zoom
lens features a simplified weather-resistant construction and extra-smooth
autofocus operation using a built-in motor, in addition to its high 7.5X zoom
ratio.
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, maneuverable 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-molded 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 minimizing the streaking effect of point
light sources.
