r Camera Characteristics
• Features a 23.5×15.7 mm CCD with 6.1 million effective pixels for high
precision and a wide dynamic range.
• Features an AF sensor with 11 focusing points. The central 9 are wide
area cross sensors.
• Features a viewfinder similar to that of a conventional 35 mm camera, with
a 0.85× magnification and 96% field of view, for easier manual focusing.
Also features a superimpose function in which the AF points on the
viewfinder illuminate red.
• 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/wide-field viewing performance.
• Features a Digital Preview function for checking the image to ensure that
the desired result is achieved.
• A user-friendly design has been implemented in 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 r 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
r 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
r. To obtain 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
r.
Inversely, multiply the focal length of the lens used with r by 1.5 to
determine the focal length for 35 mm cameras.
Example) If 300 mm lens is used with r
300×1.5=450
Focal length is equivalent to a 450 mm lens on a 35 mm camera.
