This unifocal standard lens offers a focal length equivalent to 61mm in the 35mm format, and measures a mere 9.2 mm 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 photographic situations, including snapshots, scenic photos, portraits, and even low light indoor shooting.

SP coating to block dirt and dust
The front surface of this lens is treated with an SP (Super Protect) coating, which applies an exclusive fluorine compound to the lens surface through a vapour 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.
