12 L Camera Characteristics Before Using Your Camera • Features a 23.5×15.7 mm CCD with 6.1 million effective pixels for high precision and a wide dynamic range. 1 • Uses CR-V3, AA lithium batteries, rechargeable AA Ni-MH batteries or AA alkaline batteries. • Features a large 2.5-inch LCD monitor with 210,000 pixels and a brightness adjusting function for high-precision viewing performance. • Concepts of Universal Design have been implemented to various parts of the camera. The large, high-resolution LCD monitor and easy-to-use menus make the camera easier to operate. The captured area (view angle) will differ between the L and 35 mm SLR cameras even if the same lens is used because the format size for 35 mm film and CCD are different. Sizes for 35 mm film and CCD 35 mm film : 36×24 mm L CCD : 23.5×15.7 mm Angles of view being equal, the focal length of a lens used with a 35 mm camera must be approximately 1.5 times longer than that of L. To obtain a focal length 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 L. Inversely, multiply the focal length of the lens used with L by 1.5 to determine the focal length for 35 mm cameras. Example) If 300 mm lens is used with L 300×1.5=450 Focal length is equivalent to 450 mm lens on a 35 mm camera.
