Page 7: Foreword
FOREWORD The Nikon Photomic FTN Finder incorporates a precise center-weighted CdS exposure meter which couples to the camera's lens aperture diaphragm and shutter speed controls. It makes possible easy, accurate thru-the-lens exposure mea- surement with the Nikon F. This instruction booklet has been prepared to help you get the most out of your Photomic FTN Finder. -
Page 8: Checking The Batteries
CHECKING THE BATTERIES The Photomic FTN Fmder is powered by two 1.3 volt mercury batteries located in the battery chamber on the bottom of the finder. To check the batteries, press the meter switch-off button and observe the needle in the window on top of the fmder. -

Note: When using flash, be sure to set the camera for flash by lifting up and turning the milled synchro-selector ring. Refer to the "Flash Syn- chronization" section in the Nikon F instruction manual. -
Page 10: Shutter Speed Coupling
ATTACHING THE PHOTOMIC FTn FINDER Shutter Speed Coupling When the Photomic FTN Finder is attached to the camera, the shutter speed dial on the camera is covered by the finder unit. Therefore, an auxiliary shut- ter speed scale is provided on the finder. With the FTN Finderim place, twist the shutter speed selector right and left until it engages the dial on the camera and the two rotate together. -
Page 11: Lens Aperture Couplmg
The scale has a range from f/1.2 to f/5.6. For example, if the 50mm f/1.4 lens is mounted on the camera, the red index mark should appear between 1.2 and 2.8. For instructions for mounting and removing lenses, see the Instruction Booklet for the Nikon F. -

ATTACHING THE PHOTOMIC FTn FINDER Setting the Film Speed Lift and tum the milled ring around the ASA film speed dial so that the red triangular index mark on the ring lines up with the number corresponding to the ASA rating of the film loaded in the camera. The film speed dial covers a range from ASA 6 to 6400. -
Page 13: Turning On The Meter
Turning On the Meter Switch on the meter circuit by pressing in the meter switchon button located on the side of the finder. The meter switch-off button will then pop up and a red line around its circumference will be visible. This serves as a warning that the meter is on. -
Page 14: Exposure Measurement With The Photomic Ftn Finder
EXPOSURE MEASUREMENT WITH THE PHOTOMIC FTn FINDER (Full-Aperture Measuring Method) The Photomic FTN uses a center-weighted thru-thelens metering sys- tem that reads the light over the entire focusing screen but favors the central portion of the screen. This means that it is possible to get cor- rect exposure in situations where an averaged reading of the entire screen would result in underexposure of the main subject-with strongly back- lighted portraits, for example. -
Page 15: Centering The Needle
Centering the Needle The correct exposure is found by centering the meter needle, either im the V-shaped notch which is visible in the viewhinder or at the central mark located beneath the window on top of the finder. Tum either the shutter speed selector or lens aperture ring until the needle is centered. -
Page 16: Getting The Right Exposure
EXPOSURE MEASYMENT WITH THE PHOTOMIC FTn FINDER Getting the Right Exposure The central part of the focusing screen should always be aimed at the main subject when centering the needle. Otherwise unimportant bright or dark areas may influence the exposure reading. If an off-center composition is desired, first measure the light striking the main subject and set the aperture and shutter speed to center the needle. - Page 17 For correct exposure, first measure the light Measuring the bright area in the center of the striking the main subject, then compose and screen will cause underexposure of the main shoot. subject.

Page 18: Measurement By The Stop-Down Method
MEASUREMENT BY THE STOP-DOWN METHOD With the following lenses and accessories full-aperture exposure measure- ment is not possible, either because the lens has no auto-diaphragm or be- cause the diaphragm will not couple with the Photomic FTN meter. There- fore, the stopdown method must be used. This means measuring exposure with the lens aperture diaphragm stopped down to the taking aperture. -
Page 19: Preset Lenses
Bellows FocusingAttachments, Extension Rings and Focusing Unit To detemmine exposure, select the desired strutter speed and stop down the lens manuaUy until the needUe centers. Preset Lenses Use the same procedure as above for lenses having preset diaphragms, such as the PC-Nikkor 35mm f/2.8. Auto Lenses Without Coupling Prong Some lenses like the Zoom-Nikkor Auto 200-600mm f/9.5 have an auto diaphragm but no coupling prong. -
Page 20: Exposure Correction
EXPOSURE CORRECTION Special Lens-Focusing Screen Combinations Because the light-transmitting properties of some focusing screens differ from those of ordinary screens, certain lensscreen combinations require exposure correction to compensate for the influence of the screen. Compensating marks from -2 to +1/2 are engraved around the ASA film speed dial. - Page 21 A / L K / P 6mm f/2.8 - 1 / 2 - 1 / 2 Fisheye 8mm f/2.8 - 1 / 2 - 1 / 2 16mm f/3.5 15mm f/5.6 - 1 / 2 20mm f/3.5 - 1 / 2 - 1 / 2 24mm f/2.8 Wideangle...

Page 22: Repro-Copyimg
Repro-Copying For originals such as photographs which have tonal gradations, exposure is determined in the usual way. In the case of originals having strong contrast and no gradation, such as documents or line drawings, measure the brightness of the white portion of the original (if the original is predominantly black, a sheet of white paper may be substituted) after decreasing the film speed by four marks. -
Page 23: Care And Handling
CARE AND HANDING Your Photomic FTN Finder is ruggedly constructed. However, it deserves the same care you would give any preci- sion instrument. Follow the simple precautions given below and the Photomic FTN will give years of dependable service. • Store the finder in a case to keep out dust.
