Our take on the Pentax DA 40mm f/2.8 Lens by Crutchfield's Woody Sherman
Milestones don't last for long anywhere in the world of photography. That being said, this is the single thinnest interchangeable lens we've ever seen, on any camera system (as of spring 2012). And even though it's a lens you could conceivably slip into a vest pocket, it's got optical properties that today's digital photography enthusiasts will find compelling. With its light-seeking f/2.8 aperture, this lens will make the most of the light in your environment. And with an effective 61mm focal length, it's ideal for snapshots and portrait photography.
This lens is a product of renowned designer Marc Newson's imagination, and it makes an artistic impression on the front of the Pentax K-01 camera.
