[. . . ] If this lens is used with cameras not compatible with vibration reduction, set the vibration reduction ON/OFF switch # to [OFF]. With the Pronea 600i/6i camera, in particular, battery power may become quickly depleted if this switch is left [ON]. This is a high-performance Micro lens featuring special Vibration Reduction (VR2) and highspeed Internal Focusing (IF) mechanisms. [. . . ] 2 Vibration is reduced when the shutter release button is lightly pressed. Because vibration is reduced in the viewfinder, auto/manual focusing and exact framing of the subject are made easier. Wait until the image in the viewfinder stops vibrating before fully depressing the shutter release button after you have lightly pressed the shutter release button. If you move the camera in a wide arc when panning, vibration in the direction of that movement is not affected. For example, if you pan the camera horizontally, only vibration in the vertical direction is reduced, making smooth pans much easier. Due to the characteristics of the vibration reduction mechanism, the image in the viewfinder may become slightly blurred after releasing the shutter. Do not turn the camera power OFF or remove the lens from the camera while the vibration reduction mode is in operation. (Otherwise, the lens may emit a chattering noise if the camera is shaken. ) · With F80-Series/N80-Series, F75-Series/N75-Series, F65-Seris/N65-Series, D200, D100, D70-Series and D50 cameras featuring a built-in flash, vibration reduction does not work while the built-in flash is recycling. However, set the switch to [ON] when using a tripod without securing the tripod head, or when using a monopod. With AF cameras featuring an AF start (AF-ON) button, such as D2-Series, D200, F6 and F5 models, vibration reduction will not operate even if the AF-ON button is depressed. The depth-of-field indicators % are engraved beside the distance index line &. At close distances, however, so little is in focus that it may be better to check the depth of field table (on page 86). If your camera has a depth of field preview button or lever, use it to check the depth of field in the viewfinder. The reproduction ratio is the relation between the size of the image recorded on film and the actual subject size. If, for example, the image on the focusing screen is onefifth the actual subject size, the reproduction ratio is 1:5. [. . . ] Do not get water on the lens or drop it in water as this will cause it to rust and malfunction. 8 14 elements in 12 groups (1 ED glass and 1 Nano Crystal Coat-deposited lens elements) 23°20' [15°20' with Nikon digital cameras (Nikon DX format); 18°40' with IX240 system cameras] 1:10 to 1:1 (life-size) Output to camera body Nikon Internal Focusing (IF) system (utilizing an internal Silent Wave Motor); manually via separate focus ring Provided; two ranges available: Full (-0. 5m Lens-shift method using voice coil motors (VCMs) Graduated in meters and feet from 0.
