As for the new lens, it's the Pentax-DA 40mm F/2.8 XS pancake. Pentax is claiming that it's the world's thinnest, measuring just .36-inches thick. That's actually probably thinner than some actual pancakes, depending on what diner you frequent. It focuses as close as 16-inches, has a Super Protect coating, and has an effective focal length of 61mm on an APS-C sensor. And, because it's plain old K-mount, it'll work on your current Pentax DSLRs as well.
