A super-telephoto zoom lens covering the focal lengths from 150mm to 450mm, which is highly demanded by high-end PENTAX-camera users

There are many situations where it is not possible to get close to the subject. The best example of this is wildlife photography. Whether in the zoo at home, in a wildlife park or on safari, a lens in this focal length range is an indispensable accessory. With the 35 mm full-frame sensor of a K-1 Mark II, the focal length range of 150-450 mm is available, and the crop factor of APS-C cameras, such as the K-3 Mark III or the K-F, results in a focal length range equivalent to 230-690 mm. The teleconverter HD Pentax-DA AF REAR CONVERTER 1.4AW (limited image range) extends this range by a factor of 1.4.

Outstanding image description

By incorporating three super-low dispersion glass elements and one Anomalous Dispersion Glass element in its optics, it effectively minimizes spherical and chromatic aberrations, while producing crisp, high-quality images with edge-to-edge sharpness, free of color bleeding.

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

Designed for challenging conditions

Dustproof, weather-resistant construction

Developed as an AW (All Weather) model, this zoom lens features a dependable dustproof, weather-resistant construction with 21 special seals to prevent the intrusion of water and dust particles into the lens interior.
By pairing it with a PENTAX weather-resistant digital SLR camera body, it assures a durable, reliable digital imaging system that performs superbly in demanding shooting settings — even in 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.

Newly installed three-position switch for Quick-Shift Focus System

In order to improve its operability, a three-position switch is newly installed on this lens, allowing instant switching among QFS/A, QFS/M and MF modes. QFS/A is an autofocus-priority mode, which allows the user to switch to manual-focusing operation only when autofocus operation is completed. QFS/M is a manual-focus-priority mode, which enables the user to switch to manual focusing at any time — even when the AF system is in operation. MF mode allows the user to instantly switch to manual focusing with a simple twist of the focus ring on the lens.
With a choice of three distinctive modes, the user is assured of speedier, more accurate focusing operation for a given subject or application.
There is also a focus range limiter to minimize AF operation time by fixing the focus range to one of three subranges

Four AF buttons installed on the lens barrelI

In order to provide more stable AF operation and better hold of the lens regardless of the camera’s orientation — horizontal or vertical — this lens provides four AF buttons on its barrel — one at every 90 degrees.* The user can assign preferred settings to these AF buttons, including: a Focus Preset mode to preprogram the focus position and instantly shift the focus to that position; and an AF Cancel mode to intentionally fix the focus at a desired point during Continuous AF operation.

* Corresponding models are K-1 Mark II, K-1, KP, K-3II, K-3, K-70, K-S2, K-S1. For K-3 and K-S1, Firmware upgrade is required.

Others

Direct Current (DC) focus motor.

It performs autofocus operation via a motor in the lens barrel. This provides quieter and smoother AF oper-ation than AF operation in the camera body, and allows for easy, comfortable focusing.

Lens Hood included

In addition to a variety of features, such as our unique multi-coating and the prevention of reflections in the lens barrel, a large special lens hood is included with this PENTAX lens to minimise ghosting and flare that occurs in backlit and other adverse conditions. As such, the lens hood is an integral part of the optical sys-tem and should always be used when using the lens. Most PENTAX lenses are designed so that the lens tip does not rotate when zooming and focusing to facilitate the use of circular polarising filters. This is fur-ther supported by a small window in the lower part of the aperture to allow the circular polarising filter to be operated.

Detachable tripod mounting with a newly designed anti-falling mechanism.

For better balance when mounting, this lens has a detachable tripod mount. For safe handling, this is equipped with a newly developed fall protection. The tripod mount can be used for portrait and landscape format

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.
