out of focus
Turn the focusing ring of the lens as you look in the viewfinder until the main subject is sharp. The three focusing aids of the standard screen can be used alone or in combination according to the subject and your own preference.
The New Canon F- 1's focusing screen. which makes precise focusing possible, also determines the metering sensitivity area. There are 13 types of focusing screens and three different metering areas optionally available to suit your particular focusing and metering requirements.
1. New Split Rangefinder
The new split-image rangefinder divides the subject in half horizontally and is especially useful for a subject which has vertical lines. The subject is in focus when the two halves merge to become one unbroken image. When using a lens with a maximum aperture of f/5.6 or smaller, one-half of the split-image rangefinder may take on,a slight color.
2. Microprism Rangefinder
When the subject is out of focus, the microprism ring breaks the subject into tiny fragments, causing a shimmering effect. It is clear and steady when your subject is in focus.
3. Laser-matte Screen
The laser-matte screen appears fuzzy until the subject is -in focus. It is particularly effective when you are using accessories for copying or close-ups.
Ten eyesight correction lenses from +3 to -4 diopters are available. They may make viewing and focusing easier if you are near- or farsighted. Choose the one closest to your eyeglass prescription, then make a practical test if possible.
Loading the Film
Pressing the safety stopper, pull up the rewind knob until the camera back pops open. Be sure to shield the film from direct sunlight while loading. Place the cartridge in the film chamber as shown. Then push down the rewind knob, turning it until it drops into its normal position.
Remove the plastic insert from the pressure plate before loading the first film cartridge.
Pull the film leader across the camera and insert the tip into any slot of the take-up spool.
Advance the film once. Make sure the sprocket teeth engage the film perforations.
The film should be taut. If there is any slack, unfold the rewind crank and gently turn it in the direction of the arrow until it stops. Note that the rewind crank must be unfolded before you turn it; otherwise, the knob will turn freely. Then fold the rewind crank back in. Close the camera back.
Take several blank shots, releasing the shutter and advancing the film until the frame counter reaches "1." While doing this, keep an eye on the rewind knob. If it rotates in ,the direction of the arrow, the film is loaded correctly.
NEVER remove the camera's rewind coupler cover from the baseplate when film is loaded in the camera. This will expose the film to light. It is not necessary to remove the coupler cover except for attaching the AE Motor Drive FN.
Setting the ASA/ISO Film Speed
Turn the setting dial, while pressing the lock release button, until the desired film speed aligns with the index. The dial cannot be turned lower than ASA6 or higher than ASA6400. The table on the next page shows the ASA/ISO film speeds which can be set on the New Canon F-1. Figures in parentheses are intermediate speeds which are indicated by dots on the ASA/ISO dial.
ASA/ISOis a numerical rating of the film's sensitivity to light. The higher the number, the faster the film and the more sensitive it is to a given amount of light as compared to a film with a lower number. The film manufacturer's ASA/ISO rating can be found on the film cartridge, the carton, and the data sheet.
For correct exposure, make sure the exposure compensation dial is set at "1".
Each time you advance the film, the frame counter also advances to the next number. It can count up to 39 frames. The numbers 1, 12, 20, 24 and 36 are in orange, the latter four to call your attention to the fact that rolls with those numbers are or are almost finished. The frame counter automatically returns to "S" when you open the camera back. During multiple exposures, the frame counter advances each time you wind the advance lever.
The New Canon F-1 will also accept bulk film loaded into standard cartridges. In this case. be sure to trim the leader as shown before loading it into the camera.
The camera back has a memo holder. It conveniently holds the end of the film box as a reminder of the type of film in use and the number of exposures.
