Pentax K20 has a very favourable price compared to it’s competitors. Also the ability to fine-tune the auto focus system so that if a lens is front or back-focusing, you can correct for it is a very nice otion. This allows you to change the relationship between the point you focus on to the front-to-back area around that object that is also in focus known as the depth of field. This feature could save you a lot of heartache with poorly calibrated lenses that would otherwise be useless. A significant new feature is the new imaging device from Samsung, producing excellent low noise quality photos at sensitivities as high as 1600 ISO. The RAW button on the left side of the camera body enables you to shoot most of the photos in JPEG, but allows you to switch to RAW for a single image to get the most out of it. This feature really conserves memory card space, but at the same time allows shooting of intermittent RAW images when they are really needed. The internal software of the camera has really been upgraded and includes an in camera capability to convert RAW images to TIFF or JPEG, a really neat feature if one is on the road and doesn’t have access to the computer software necessary to process RAW images but yet wants to view them on other portable imaging devices.
