The K500 is essentially the same as the K50 without the weather sealing or the weather sealed kit lens. As such, it becomes one of the least expensive camera bodies to have two command wheels, or to reach up to ISO 51,200. Plus, the fast shutter speed of 1/6000 second is quite rare in this price range, let alone the pentaprism's 100% finder coverage. The other big difference between the K500 and its pricier sibling is that the K500 uses AA batteries. You can step up to a Li-ion battery if you choose, though the price of the battery hasn't been released at press time. The K500 is expected to sell for $600 with 18-55mm f/3.5-5.6 DA-L kit lens, or $700 for the body, that 18-55mm lens, and a 50-200mm DA-L lens. So far, it doesn't seem like the K500 will be offered body only, which isn't uncommon for entry-level Pentax DSLRs.
