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.
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.
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.
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.
It is further noted in another reply comment of his that the new K-01 will not have any viewfinder, no EVF nor OVF neither.

9.2mm and 52g, that’s impressive, though it looks like it’s going to be a heavy camera compared to the competition, nice coat pocket option? Can we have an f/2 at twice the length and weight? Or an f/1.4 at 4 times.
OMG! at 9mm you could now put an aps-c sensor, into a cell phone!
not sure anyone will, but one could.
60mm equivalent is too long for general use and too short for portrait. Seems like they picked this only because they could easily recreate it from their existing 40mm lens. A poor choice for a first lens.
Not sure I would want to invest in this system as it looks like Pentax is just throwing something out there to try and capture mirrorless sales without investing much time or money. Similar to Canon’s G1X entry they are both half-baked solutions. I bet the Pentax AF speed is slow too.
I don’t understand their choices of focal lengths… Thy always seem to be between the useful range… :-/
agree 40mm all most useless
Everyone has bad days, so does Mark Newson. :O
No EVF? It will feel like a big brick point and shoot
no evf what in the world , how do you use this with a long lens with out a evf
