1. Highest level of optical quality
The new smc PENTAX-DA* series has been developed through PENTAX's unending
pursuit of the ultimate image quality in digital photography. Bringing together its
advanced optical technologies, including aspherical elements, special optical-glass
elements and original lens coatings, PENTAX successfully developed a new
interchangeable lens series that is superior to any existing lens series in terms of contrast,
clarity and description, even at the edges.

2. Innovative SDM System for smoother, quieter autofocusing operation
These two new smc PENTAX-DA* zoom lenses come equipped with a new SDM System,
which assures smoother, quieter autofocusing operation using a built-in supersonic motor.
When mounted on the PENTAX K10D digital SLR camera body, the focus mode is
automatically switched to SDM-assisted autofocusing.* When mounted on other PENTAX
digital SLR camera bodies, the conventional autofocus mode using a camera-mounted
motor is selected.
* The PENTAX K10D firmware must be updated to take advantage of this automatic switching function.

3. Reliable weather- resistant and dust-resistant construction
The smc PENTAX-DA* series features a tightly sealed, weather-resistant and
dust-resistant construction to enhance durability for use in the rain or at the dusty
locations.

4. Original Quick-Shift Focus System for instant switching to manual-focus operation
The PENTAX-developed Quick-Shift Focus System allows the user to instantly switch to
manual-focus operation without any mode changes, after the subject is captured in focus
by the AF system. This user-friendly system can be used in both the SDM-assisted
autofocus mode using a lens-mounted supersonic motor and the conventional autofocus
mode using a camera-mounted motor.

5. SP coating to protect the lens against water and grease
The PENTAX-original SP (Super Protect) coating is applied to the front surface of this
lens. Through a vapor deposition process, the lens surface is coated with a special fluorine
compound to repel dust, water and grease, making it easy to wipe off fingerprints and
cosmetics.

6. Digital SLR-exclusive optical design
This lens is exclusively designed for use with PENTAX digital SLR cameras, with an
image circle perfectly proportioned to the CCD size (23.5mm x 15.7mm), and optics
optimized for digital imaging characteristics. Combining high-quality image reproduction,
it is a perfect partner to PENTAX digital SLR cameras.
