1. Exterior design by Marc Newson
Together with the PENTAX K-01 camera body, the exterior of this lens has
been designed by Marc Newson. Mounting this lens on the K-01 results in a
highly stylish imaging tool. 【宣传说外形很骚，宣传说k01外形也很骚。。这个我

2. Easy-to-use, super-thin lens for everyday use
This unifocal standard lens offers a focal length equivalent to 61mm in the
35mm format, and measures a mere 9.2 millimeters in length, making it the
world’s thinnest interchangeable lens. Thanks to its super-thin design, it
is highly portable and easy to store and carry. Its optics were designed
based on those of the acclaimed smc PENTAX-DA 40mm F2.8 Limited lens. Its
maximum aperture of F2.8 produces sharp, bright images in a wide range of
applications, including snapshots, scenic photos, portraits, and even
incident-light indoor shooting. 【超小，超方便】
3. Exceptional image-description
In addition to numerical evaluations made by various testing machines,
PENTAX has also conducted an image-quality evaluation of hundreds of images
actually taken with this lens. As a result, it not only offers outstanding
specifications, but also demonstrates exceptional image descriptive power
and an image rendition unique to this lens. It features a round-shaped
diaphragm, which produces a smooth, natural bokeh (out-of-focus) effect in
the background. 【锐度出色，镜头气氛好】
4. SP coating to block dirt and dust
The front surface of this lens is treated with SP (Super Protect) coating,
which applies an exclusive fluorine compound to the lens surface through a
vapor deposition process. This SP coating not only repels dust, water and
grease, but also makes it easy to wipe off oily stains such as fingerprints
and cosmetics. 【招牌防油SP镀膜】
