Auto Film Loading/Advancing:

One of the big improvement on film handling was the adoption of ISO standard on bar-code reading of film roll back in the mid '80. It facilitates auto recognition, hence provides a quick, easy and positive film handling process in any camera. Along the way, mistakes by human error is reduced to bare minimum level. The Canon EOS-1N wasn't the first among the Canon camera models (I think again, the Canon T90, 1986 was) and its adoption of both built-in film advance/rewinding with the DX coding has actually simplifies the entire process of pre-shooting setup.

DX Coded Film Roll
When DX film is loaded, the film speed is set automatically according to the DX code on the film cartridge. The automatic film speed setting range is ISO 25~5000. • If non-DX film is loaded, the ISO indicator and the numbers for the previously-set film speed blink in the LCD panel. Set the appropriate film speed according to instructions in “1. For those still practicing film push and pull process (esp.in black & white); Manually Setting the Film Speed” is also possible.

  To set a film speed other than the automatically-set DX film speed, The manually-set film speed is automatically canceled when new DX-coded film is loaded.. The currently set film speed can be checked by simultaneously pressing the AF mode selector and metering mode selector. The “ISO” indicator and the currently set film speed are displayed in the LCD panel.
  Although unlikely this can happened, because Canon EOS-1N was actually a discontinued model, but when it was purchased new, one has to remove a plastic protector from inside the back cover. If the plastic protector is left inside the camera while taking pictures, the characters printed on the plastic may appear in the exposed image.

1 Set the main switch at the camera (bottom rear section) to “A”. 2 Open the back cover by using your thumb to press the back cover lock release button while sliding the latch down. If you find it difficult to perform both operations with one finger, use one finger to press the back cover release button and another finger to operate the latch.

3 Insert the film cartridge at a slant with the flat end facing up and the bottom end entering the camera first.

If you pull out too much film, wind the excess back into the cartridge. The shutter curtain operates with extremely high precision and can be easily damaged if touched. When loading or unloading film, BE CAREFUL not to touch the shutter curtain accidentally with your finger or the tip of the film.

5 After checking that the film tip is aligned with the orange mark and that the film perforations are engaged with the sprockets, close the back cover until it clicks shut.

WARNING: AVOID touching the delicate shutter curtain while changing film, can be a painful exercise for replacement.
AVOID pull the film tip past the orange mark. If the film tip passes the orange mark, advancing the film may damage the film or may even cause the camera to malfunction momentarily.

6 The film automatically advances to the first frame, the frame counter shows “1” and the film-load check symbol is displayed in the LCD panel. If the film transport (wind/rewind) blinks, the film is not loaded correctly, and the shutter will not release when the shutter button is pressed. Reload the film. Note:- Using film which has been exposed to high humidity may cause the film perforations to tear when the camera advances the film. In humid locations, do not remove the film from its original sealed package until immediately prior to loading it into the camera.

<<<--- Quality of materials were used througout. It helps to project rigidness of construction, as well as the kind of precision which boosts user's confidence - Other than that, it is also one of the many reasons why sometimes, professional class bodies are justified in their higher retail price than most mass-produced consumable models.

Removing Film The film automatically rewinds at the end of the roll. 1 When rewinding starts, the film rewind indicator moves from right to left to show that the film is rewinding. At the same time, the LCD panel's frame counter counts down the number of frames.

2 Automatic rewind stops when completed. Film rewind completion “” blinks in the LCD panel to indicate that you can now safely open the back cover and remove the film.

Removing Film in Mid-Roll () To rewind the film in mid-roll, press the film rewind button ( ). The film immediately starts rewinding. What happens IF camera runs out of gas (power) during mid-roll shooting ? After changing to a new power cell(s), Just use a sharp object to push the concealed mid-roll film rewind button, Everything will resume.

1. Manually Setting the Film Speed If you wish to set a film speed other than the DX-coded film speed. Set the film speed after loading the film. The manual film speed setting range is ISO 6~6400. When using DX film, the automatic film speed setting range is ISO 25~5000.

1 While simultaneously pressing the AF mode selector and metering mode selector/flash exposure compensation button, turn the main dial to the left or right until the desired film speed is displayed in the LCD panel. When the AF mode selector and metering mode selector are pressed simultaneously, “ISO” and the currently set film speed are displayed in the LCD panel. 2 Release the AF mode selector and metering mode selector/flash exposure compensation button to complete the film speed setting.

Custom Function F3 This custom function can be used to prevent the camera from automatically setting the film speed according to the film's DX code. When this function is set, the camera does not change the manually set film speed when changing film, handy when using many rolls of the same type of film in succession.
