The HD PENTAX-D FA 15-30mm F2.8 ED SDM WR is high-performance super-wide-angle zoom lens for the 35 mm full-frame image circle of Pentax DSLR cameras

Exceptional imaging performance

The D FA 15-30 mm super wide-angle zoom lens offers an impressive angle of view and, especially in combination with the 35 mm full-frame camera PENTAX K-1, allows for particularly spectacular images, e.g. in landscape photography. With the extreme perspective of the 15 mm focal length, compositions with a particularly deep image effect can be created.
At 30 mm, the lens is very well suited for reportage photography or spontaneous snapshots. When the lens is used on a PENTAX camera with an APS-C sensor, the focal length range is 23-46 mm.

Lens construction at the highest level of technology

Lens construction at the highest level of technology The optical construction of the D FA 15-30 mm lens consists of 18 elements in 13 groups. Three ED (Extra-low Dispersion) and aspherical elements ensure high-contrast and high-resolution images right up to the edge area with minimal chromatic aberrations, coma and distortion.

HD Coating to enhance imaging performance

The lens incorporates the PENTAX-developed, multi-layer HD (High Definition) Coating. Compared with conventional multi-layer coatings, it improves light transmittance while reducing average reflectance in the visible ray spectrum. This means that it can deliver clear, well-defined images with minimal flare and ghost images, even under demanding lighting conditions such as backlighting.

Designed for challenging conditions

Dustproof, weather-resistant construction

Special sealings applied throughout the lens body provide this zoom lens with dependable weather-resistant construction, effectively preventing the intrusion of water into the lens interior. By pairing it with a weather-resistant PENTAX digital SLR camera body, the photographer has a durable, dependable digital imaging system that performs superbly under demanding shooting conditions — even in the rain or mist, or at locations prone to water splashes or spray.

SP Coating
SP coating is a PENTAX-original special coating that provides superior performance in repelling water and oils. It is used on the front surface of the first high-performance lens for effective protection of the lens surface. This coating not only prevents adhesion of dust, water drops, oils, and other substances, but it also makes it easy to wipe off objects that adhere to the lens.

Supersonic AF motor (SDM)

This lens features a newly developed ring-type SDM (Supersonic Direct-drive Motor), which generates as much as 7.5 times the torque of the conventional SDM installed in existing lenses. Thanks to this enormous driving power, the lens assures a smooth, high-speed shift of the heavy, multi-element rear lens group during focusing operation.

Built-in lens hood

In addition to a variety of features, such as our unique multilayer process and the prevention of reflections in the lens housing, the lens hood is part of the construction to minimise ghosting and lens flare when shooting into the light and in other unfavourable conditions.

Others

Nine-bladed diaphragm mechanism, for a natural, beautiful bokeh (blurring) effect up to F4 (F5.6 at 30 mm) aperture: adjustment to generate while minimising the streaking effect of point light sources.

A minimum focusing distance of 28 centimetres, which captures images with a blur effect.

Quick-Shift Focus System, which allows the user to instantly switch to manual focus mode after the subject has been focused by the camera's AF system.

MTF chart information

MTF (Modulation Transfer Function) is a kind of index used to evaluate lens performance, which represents the extent of subject contrast reproduction as spatial frequency.
The MTF chart here shows the contrast on the vertical axis, and distance from the center of the image on the horizontal axis. For the spatial frequency, 10 lines/mm shows a low frequency, and 30 lines/mm shows a high frequency, resulting in the MTF graph. On the graph, the solid line represents the S direction (sagittal direction and radiation direction) MTF, and the broken line represents the M direction (meridional direction and concentric circular direction) MTF.
In general, a low-frequency MTF is proof of a clear, high-contrast lens, and a high-frequency MTF is proof of a sharp lens with high resolving power.

PENTAX K Mount

The lens mounts for PENTAX interchangeable lenses are based on the bayonet K mount, which has remained unchanged since its inception in 1975. It is a mount unique to PENTAX that features a large aperture combined with superior ease of replacement, accuracy, and toughness. These features are utilized to comfortably incorporate an iris control mechanism, autofocus mechanism, and other functions for enabling nearly complete compatibility with conventional lenses. The PENTAX K Mount keeps its advanced versatility despite differences in camera and lens functions.
