Nikon 1000MM instruction manual Using the Filters, Obtaining Correct Exposure

USING THE FILTERS C

The Reflex-Nikkor 1000mm f/11 is provided with a set of five filters for attaching individually to the rear of the lens. To attach a filter, remove the lens from the camera body in the normal way and simply screw the desired 39mm filter onto the threaded filter mount provided at the rear of the lens. Note that the lens comes with the L37C filter mounted on the lens, with the remaining four filters stored in the filter case in the flap of the lens case; one filter must be mounted at all times on the lens. In addi- tion to the supplied set of five 39mm-diameter filters, the following 39mm screw-in filters are available as optional equipment: Skylight (L1BC), Medium Yellow (Y48), Deep Yellow (Y52), Red (R60), Neutral Density (ND2X and ND8X), Amber (A12), Medium Blue (B8), and Deep Blue (B12). The following table details the various 39mm filters available from Nikon.

Colorless filters for subduing all colors uniformly; useful for control of bright sub- jects; see "Controlling the Exposure" on page 11 for details.

Provide for pronounced contrast for accentu- ating details; as filter factor increases, greater contrast is achieved; filter R60 used with infrared film.

OBTAINING CORRECT EXPOSURE

Your lens is the fixed-aperture type and will not couple with the TTL exposure meter- ing system that may be built into some camera bodies. To get the correct exposure, please refer to the stopped-down exposure measurement section in the camera's instruc- tion manual.

Remember that even if you set the camera to its top shutter speed, you won't be able to obtain correct exposure. A rule of thumb is to use the neutral density filter.
