17 • Features Sensitivity Priority mode K that automatically adjusts aperture and shutter speed according to the set sensitivity. • Supports infrared transmission (IrSimple/IrSS) which allows you to send and receive image data to and from cell phones and printers. Shake Reduction (SR) 1 Shake Reduction (SR) on the W features a PENTAX original system which uses magnetic force to move the image sensor at high speeds, compensating for camera shake. The camera may generate some operating noise when it is shaken, such as when changing the composition of a picture. This is normal and not a malfunction. Before Using Your Camera Additionally Saving as a RAW Image When the file format of the last captured image is JPEG, and its data still remains in the buffer memory, you can additionally save the image in RAW format by pressing the mc button during playback. If the image was shot using any of the following settings, the corresponding RAW image listed is saved. • Cross Processing RAW image without Cross Processing • Digital Filter RAW image without filter effect • HDR Capture RAW image with standard exposure • Multi-exposure RAW image with Multi-exposure The captured area (view angle) will differ between the W and 35 mm SLR cameras even if the same lens is used because the format sizes for 35 mm film and CMOS sensor are different. Sizes for 35 mm film and CMOS sensor 35 mm film: 36×24 mm W CMOS sensor: 23.6×15.8 mm The focal length of a lens used with a 35 mm camera is about 1.5 times longer than that of the W. To shoot images with an angle of view framing the same area, divide the focal length of the 35 mm lens by 1.5. Example) To capture the same image as a 150 mm lens attached to a 35 mm camera 150÷1.5=100 Use a 100 mm lens with the W. Inversely, multiply the focal length of the lens used with the W by 1.5 to determine the focal length for 35 mm cameras. Example) If 300 mm lens is used with the W 300×1.5=450 Focal length is equivalent to a 450 mm lens on a 35 mm camera.
