Overview: The smc Pentax-DA 18-270mm F3.5-6.3ED SDM is a 15x telephoto zoom lens for Pentax D-SLR
and interchangeable lens cameras. The extended 15x zoom ratio covers the long
range from wide angle to super-telephoto, allowing you to photograph landscapes,
portraits, sporting events, and more without changing lenses.
Lens Mount: The lens has a KAF3-mount,
and can fit Pentax D-SLR and interchangeable lens cameras with KAF, KAF2 and
KAF3 mounts. This includes
the Pentax K-5, K-5II, K-30, and K-01 cameras.
SDM Autofocus System: The Pentax SDM autofocus system is
driven by a built-in supersonic motor, which offers exceptionally smooth and
quiet operation. When the lens is mounted on an SDM-compatible Pentax K-mount
digital camera, the focus mode automatically switches to SDM-assisted
Focus Mode Shifting: Focus Mode Shifting allows you to
switch the lens from Auto to Manual focus, using the switch on the lens barrel.
This can be done without changing the focus mode on the camera.
Lens Hood: The lens kit includes the PH-RBD 62mm lens hood
to keep unwanted light out of the lens, and protect the front of the lens. The hood can be
reverse-mounted on the lens for storage. When installed, the hood adds
approximately 1-7/16" to the overall length of the lens.
ED Glass: The two Extra-low Dispersion (ED) glass lens elements
effective minimizes chromatic aberration to deliver bright, high-resolution
images, even at the edges.
