Telephoto zoom lens with rich gradations and outstanding three-dimensional feel
This lens enables imaging where the target subject stands out from a background with smooth gradations.
Outstanding imaging performance with colors that remain sharp even in the details Star lens series for the digital age combining a large F2.8 aperture and compact ease-of-operation
Built-in ultrasonic motor (SDM mechanism)
This lens features a compact ultrasonic motor for enabling an internal AF mechanism (SDM mechanism). It also includes a brake function to enable easy speed and position control for smooth and precise AF operation.
When the lens is attached to an SDM-compatible digital SLR camera, operation automatically switches to the AF by the SDM mechanism (Note 1). When the lens is attached to a non-SDM-compatible digital SLR camera, AF operation can be performed by the motor in the camera body (Note 2).
Note 1: SDM-compatible PENTAX digital SLR cameras include the K-7, K20D, K200D, K-ｘ, K-m, K10D (firmware version 1.30 or later), and K100D Super. If you have K10D with firmware version 1.20 or earlier, download the compatible firmware from this website and install it to your camera.
Note 2: Non-SDM-compatible K100D and istD series cameras automatically switch over to AF operation using the internal camera motor.
