Before Using Your Camera 17 • Records images in the versatile JPEG format or the high quality and fully editable RAW format. You can also select JPEG+RAW and record in both formats simultaneously. 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. RAW images can be easily processed internally by the camera. • Up to five setting patterns can be saved in A mode. In addition, 1 functions for the |/Y button and the e-dials can also be customized, enabling speedy operation by any type of photographer. • Supports the optional Battery Grip D-BG4 with vertical shutter release button. If a battery (D-LI90) is inserted in both the camera and grip, the battery with more power is prioritized. This enables you to get the best camera performance for an extended period. A menu item also allows you to prioritize a battery and use its full power before switching to the other battery. Shake Reduction (SR) Shake Reduction (SR) on the X 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. The captured area (view angle) will differ between the X 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 X CMOS sensor : 23.7×15.7 mm The focal length of a lens used with a 35 mm camera is about 1.5 times longer than that of the X. 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 X. Inversely, multiply the focal length of the lens used with the X by 1.5 to determine the focal length for 35 mm cameras. Example) If 300 mm lens is used with the X 300×1.5=450 Focal length is equivalent to a 450 mm lens on a 35 mm camera.
