Pentax 55-300mm F4.5-6.3 WR Lens

The Pentax 55-300mm f/4.5-6.3 is an excellent telephoto zoom lens in a compact, lightweight body; perfect for outdoor sports, portrait and travel photography. Packed full of features, the 55-300mm boasts an electromagnetic diaphragm control system for ultra- quiet sound operation during movie recording, a rear focus system and a direct drive lead screw system for high-speed auto focusing. The ED lens elements ensure sharp, crisp images with great colour rendition whilst the HD coatings optimise light transmission and minimise flares reflections.

  • 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.

    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 theater stage or a sunlight-streaked forest where the brightness level fluctuates considerably, and for such active subjects as athletes and animals.

    Electromagnetic Diaphragm Unit
    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

    High-quality images, with a minimum focusing distance of 0.95 meters
    With focal lengths from 84.5mm to 460mm (in the 35mm format), this telephoto zoom lens provides approximately 5.5-times zoom coverage from medium- to super-telephoto ranges. Its 14-element, 11-group optics include an ED (Extra-low Dispersion) optical element to effectively minimize spherical and chromatic aberrations, while delivering high-resolution, fine-detailed images with rich contrast from the image’s center to its edges and minimal color bleeding at any focal length setting. In addition to the short minimal focusing distance of 0.95 meters, made possible by the rear-focus system, the lens barrel has also been designed to be free of extension during AF operation, making it ideal for a wide variety of applications, such as outdoor, sports and landscape shooting.
