Introduction
The Canon P U-B is a precision miniature camera. Careful handling and intelligent use are recommended for excellent service and perfect photographic results. It is advised to study the various mechanical movements before attempting to use the camera with film. This instruction manual provides all necessary information for perfect service in actual use. Practice handling the camera without loading it with film.
Proper care of lenses is also required. Lenses are made with high accuracy. The lens surface should be kept absolutely clean and accurately spherical for perfect performance. The primary rule is to keep the lens surface free from dust and other impurities. Please cover the lens with the lens cap when the camera is not in use. If the surface shows deposits of dust or impurities, do not try to remove them by rubbing with fingers. Instead, wipe the surface very gently with a piece of lens cloth in a circular motion.
Camera Parts and Controls
- (1) Winding Knob: Advances the film and winds the shutter. (Indicated by arrow up to a stop).
- (2) Automatic Exposure Counter: Tracks exposures.
- (3) Shutter Button: Press gently to make the exposure.
- (4) Main Shutter Speed Dial: For high speeds from 1/20 to 1/500 Sec. (To set: turn the winding knob, then lift and turn the dial to the desired speed).
- (5) Additional Shutter Speed Dial: For slow speeds, from 1 Full second to 1/20 sec. (When using speeds slower than 1/20 sec, set the top dial at '20' and then use this dial for speeds between 1 second and 1/20 sec. For 1/20 sec, set both dials at '20').
- (6) Iris Diaphragm Scale: Controls the light transmitting capacity of the photographic lens.
- (7) Lens Focusing Lever: Features an infinity catch. Pressing the knob on the end releases the catch, allowing the lens to be fixed for focusing down to 3.5 Ft.
- (8) Distance Scale: Distance can be read from the figure nearest the index mark.
- (9) Depth of Field Scale: Symmetrically engraved on both sides of the distance scale index.
- (10) Eyepiece of the Rangefinder: Combined with the viewfinder.
- (11) Window of the Rangefinder: Combined with the viewfinder.
- (12) Reversing Lever: Set to 'R' for rewinding film, set to 'A' for advancing film.
- (13) Rewinding Knob: Lift to rewind exposed film back into the magazine or film cartridge.
- (14) Accessory Clip: For holding special viewfinders or universal viewfinders.
- (15) Range Finder Magnification Changing Lever: Set to 'F' for standard lens finder, '1x' for 1.0x magnification, '1.5x' for 1.5x magnification.
Rangefinder and Viewfinder Usage
Notice: Keep your eye close behind the eyepiece of the built-in range-view finder. Ensure the circle of the reflected image is in the center of the field of vision. Otherwise, you cannot secure exact focus, or the eyesight of the finder may differ from that of the lens.
Figure 1 Description: Illustrates parallax error. When the separate range-finder focusing lever is set at 'F', this figure shows the variation between the actual field of vision of a standard lens (50mm F:3.5 or F:1.9) and the viewfinder's field of vision, which is usually attended with parallax. Lines indicate the field of vision of the lens, the finder at infinity, the finder at 12 feet, and the finder at 3.5 feet.
Figure 2 Description: Shows parallax error when the range-finder focusing lever is set at '1x'. This figure illustrates the variation between the actual field of vision of a 100mm F:4 Telephoto lens and the viewfinder's field of vision, which is attended with parallax. Lines indicate the field of vision of the lens, the finder at infinity, the finder at 13 feet, and the finder at 5 feet. Note: For near objects under 13 feet, it is advisable to use a separate viewfinder or a Vidom Universal View Finder.
Figure 3 Description: Shows parallax error when the range-finder focusing lever is set at '1.5x'. This figure illustrates the variation between the actual field of vision of a 135mm F:4 Telephoto lens and the viewfinder's field of vision, with parallax. Lines indicate the field of vision of the lens, the finder at infinity, the finder at 13 feet, and the finder at 5 feet. Note: For near objects under 14 feet, use of a separate viewfinder or Vidom Universal View Finder is advisable.
Loading the Camera with Film
- Open the baseplate by turning the opening knob half a turn from 'S' to 'O' and remove the take-up spool.
- Slide the leading end of the unexposed film (from a standard 35mm cartridge or a CANON film magazine) under the tongue of the take-up spool. (See Figure 4 for CANON Magazine).
- Holding the film magazine in your left hand and the take-up spool in your right, gently insert them into the camera, ensuring the emulsion side of the film faces the lens.
- Turn the film winding knob slightly and check to make sure the sprocket catches the perforations of the film. THIS IS VERY IMPORTANT.
- Replace the baseplate and turn the knob half a turn from 'O' to 'S'. Figure 5 shows the position of the film when properly loaded.
- Make certain that the reversing lever, located between the winding knob and the shutter speed dial, is set to 'A' (advance). (This lever is moved to 'R' after all exposures are made and the film is to be rewound).
- Turn the winding knob and click the shutter TWICE to pass the film that was exposed to light during loading.
- Set the counting dial to zero after the second winding of the shutter.
NOW THE CAMERA IS READY FOR MAKING PICTURES.
Note: Each time the shutter winding knob is turned with film in the camera, the rewinding knob turns in a reverse, counter-clockwise direction, indicating that the film is properly passing to the next exposure. If this is not the case, the film leader should be wound back off the take-up spool, and the film reloaded into the camera.
How to Make Your First Canon Picture
- Pull out the lens barrel and lock it into position by a slight turn to the right.
- Set the shutter speed on the dial by slightly lifting and turning to the proper position. Before setting the shutter speed, turn the winding knob one complete turn. When a shutter speed slower than 1/20th of a second is needed, set the slow speed dial at any desired stop between 1 second and 1/20th of a second after the top dial has been set at '20' (which represents 1/20th to 1 full second on the slow speed dial). When 1/20th is to be used, set both dials at the figure '20'.
- Set the iris diaphragm to the proper opening using an exposure meter or considered judgment.
- Determine exact focus by looking through the combined view-range finder eyepiece and turning the lens focusing lever until the two images coincide. (See Figure 6 for correct and incorrect focus).
- Press the shutter button gradually to make the exposure. YOU HAVE NOW TAKEN YOUR FIRST "CANON" PICTURE. (When pressing the shutter button with the forefinger, avoid jerking the camera by abruptly pushing the button.)
Continuing to Take Pictures and Rewinding
Keep taking pictures until you have used up the entire roll. When you reach the end of the film roll, the shutter winding knob will no longer turn; do not force it. Instead, move the reversing lever to 'R' and rewind all the film back into the original film magazine. The base of the shutter button will turn during this procedure and will stop when the film pulls away from the take-up spool in the camera. The film magazine may be removed from the camera after winding is completed and the reversing lever is moved back to 'A'.
Loading the Canon Film Magazine
The standard Canon Film Magazine is prepared to hold about 5-1/4 feet of 35mm film, sufficient for up to 36 double-frame exposures (24 x 36 mm). This cylindrical magazine contains three parts: the outer shell, the inner shell, and the center spool. A button on the top of the inner shell assists in opening and closing the film magazine.
To assemble the magazine:
- First, insert the center spool into the inner shell with the tip of the film in the slot of the spool.
- Next, introduce the inner shell together with the spool into the outer shell, ensuring both rectangular openings are aligned and open.
- When the inner shell comes to a stop, turn it to the left (anti-clockwise) until the safety spring clicks into the locked position.
- Before closing the chamber, pull the leading end of the film out several inches. This procedure should be done in a darkroom.
