smc Pentax-DA* 50-135mm f2.8ED (IF) SDM lens
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).
