This Penatx HD DA 55-300mm Lens provides focal lengths between 84.5mm and 460mm (in the 35mm format)* to cover medium- to super-telephoto ranges. Thanks to its upgraded AF performance, it assures quiet, high-speed AF operation in still-image shooting, as well as smooth AF tracking operation during movie recording to minimize operation noise caused by focus and aperture shifts. Its newly designed, high-quality optics provide a minimum focusing distance of 0.95 meters, expanding the range of photographic applications. With the adoption of a retractable structure, it measures a mere 89 millimeters in length, making it easy to carry around. Coupled with its weather-resistant construction, this zoom lens assures outstanding reliability and durability even in demanding shooting conditions.

High-speed AF operation


With the adoption of a rear-focus system, the focusing lens is 93.6 percent lighter* than the previous version. By driving this focusing lens using a pulse motor (PLM), which is directly linked to a lead screw, this zoom lens operates faster — approximately 8.3 times** at its wide-angle end and approximately 1.7 times** at its telephoto end —and quieter than the existing model.* When mounted on the new PENTAX K-70 digital SLR camera body, it assures smoother, faster AF operation with dimly lit subjects, thanks to an improved AF algorithm that exchanges AF data between the camera body and the lens with greater precision. Operability of its power-assisted focus system during manual-focus operation has also been improved. Since its distance ring is designed to accurately detect the angle of rotation and swiftly react to a change of angle, this zoom lens can shift its focusing lens smoothly in response to distance ring operation.

Electromagnetic Diaphragm Unit

Quiet AF operation and electromagnetic diaphragm control, perfect for movie recording


This is the first K-mount lens to feature an electromagnetic diaphragm control system.* When mounted on the new PENTAX K-70 digital SLR camera body, it assures smooth, high-precision aperture control during movie recording. Thanks to this state-of-the-art system, it shifts the aperture setting automatically and smoothly, even when the brightness level of the subject changes drastically in movie shooting. Coupled with the PLM mechanism, it also assures smooth AF tracking operation and exposure control, while minimizing the intrusion of focus- and aperture-shift noises during movie-recording operation. As the result, it produces more natural, true-to-life movies in locations such as a theatre stage or a sunlight-streaked forest where the brightness level fluctuates considerably, and for such active subjects as athletes and animals

This lens features a KAF4 lens mount compatible with an electromagnetic diaphragm control system. In order to use this lens, the camera’s firmware must be upgraded to the latest version (except for the PENTAX K-70). If this lens is mounted on a camera without proper firmware upgrade, its diaphragm control mechanism becomes inactive, making it impossible to obtain correct exposure. Cameras compatible with this system: PENTAX K-70, K-1, K-3 II, K-S2 and K-S1.

Customer Reviews (4.6 / 5 · 5 reviews)

Robert ★★★★★

The autofocus on this lens is impressively quiet and quick, making it easy to track birds without startling them. Even handheld at the long end, the image stabilization helped me get crisp shots in low evening light.

James ★★★★★

I've been using this lens for wildlife shots, and the weather-sealed build gives me confidence in damp conditions. The reach is impressive for the size, and images stay sharp even at 300mm.

Nicholas ★★★★★

The autofocus is so quiet and fast that I can finally capture birds in flight without any shutter lag, and the 460mm equivalent reach is exactly what I needed for wildlife photography. The build feels solid in hand, and images come out sharp even at the long end.
