Pentax HD DA 55-300mm f/4.5-6.3 ED PLM WR RE Lens

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 (scheduled to be launched in the existing model.* When mounted on the new PENTAX K-70 digital SLR camera body (scheduled to be launched in June, 2016), 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. read more
