Canon F-1

The Canon Camera Company became well respected for both their rangefinder cameras and the lens manufacture during the 1950s. They had an early start in the 1930s using Nikkor lenses. Their first attempt on a professional SLR camera was the remarkable 1959 Canonflex, also their very first SLR camera, which never became a success despite the high quality build. This time Canon has worked hard to regain a place among the professional camera makers, a position held for a decade by Nikon. At this time there are no prosperous European camera makers left, although a few still are in business.

The Canon way has been a diversified one, manufacturing a wide variety of interesting products for almost every market segment, but they lacked concentration in any one particular direction, at least in terms of cameras. The original Canonflex was remarkable, but it was not wholeheartedly backed up, and soon it disappeared. The superb range of Canon FL lens-mount SLR cameras that followed, was not intended for the professional photographer, giving the competition a ten year lead in that field. However, a vast majority of young amateur photographers became acquainted with the Canon FX, FP, FT and TL, or even the famous Pellix, and inevitably, some of these would become professional photographers and select a familiar brand.

The name Canon F-1 describes two very different cameras: a fully manual model, and a later electronically controlled model. The latter is often termed the New F-1. Finders, drives and accessories designed for the F-1 do not fit the New F-1, or vice-versa. There is also, frustratingly, a variant of the original F-1 called the F-1n which is a small update and fully compatible with the original. The way to differentiate these models is as follows: the original has a lever to wind a mechanical self timer, and a non-standard flash shoe around the rewind crank, similar to Nikons. The F-1n introduces plastic tips for the rewind lever, a memo holder on the back and was sold with the later style of lenses. The New F-1 has a body grip covering a battery compartment, slightly different dimensions, and a top-mounted flash shoe on both of the eye-level finders. New F-1's may also bear a 1984 Los Angeles Olympics badge on both the front and the inside of the memo holder, and these are known as the "L.A. edition," being a cosmetic variant only.

The Canon F-1

The Canon F-1 is a 35mm SLR camera introduced in the summer of 1970, together with the new Canon FD lens mount. It became generally available the following year. An FD lens fully communicates with the camera, and there is a capable range of lenses to choose from. They are backward compatible with the earlier Canon cameras. The FD lenses have an Automatic position on the aperture ring, at first identified by a green circle, later by a green A. This position is excluded if the lens is on a camera not supporting the automatic mode. The 1 to 1/2000 sec shutter has horizontally running metal foils curtains.

The TTL metering on the Canon F-1 is a remarkable feature. The photocell is neither in the finder prism nor behind the SLR mirror, but on the side of the focusing screen, which directs a fraction of the light to it. In this way the meter works independently of the attached finder, dramatically simplifying the viewfinders as well as the metering system in the camera. The beauty of it is the focusing screen with an embedded mirror. The exposure meter uses the 1.35 volt mercury battery, which fortunately may be replaced, using an ordinary hearing aid battery that is so cheap that it doesn't matter how long they last. The finder prism is neatly slid on, and focusing screen is easily lifted out.

A separately available Servo EE Finder provides shutter-priority automatic exposure using an arm attached to the left-hand side of the finder to operate the lens diaphragm, reached through an elongated tiny door at the left-hand side of the mirror housing. It must be opened using a fingernail before attaching the arm. A separate battery case, equipped with a belt clip, holds the eight required 1.5 volt penlight batteries. When they are loaded and all electrical connections established either automatic or manual exposure function is activated using the right-hand switch. The incorporated lever is just added for speedy operation of the meter switch. The automatically selected aperture is shown on a scale to the right in the finder. This is particularly useful equipment for remote controlled or automatic interval photography used in connection with the Motor Drive MF. This combination weighs 7 lbs, or about 3.2 kg, with eighteen AA batteries and the FD 55mm 1:1.2 standard lens.

The Motor Drive MF is easily mounted once the camera battery-compartment cover is temporarily removed, and the base plate set aside. It needs ten 1.5 volt penlight batteries held inside the large right-hand grip with a soft-touch shutter release button at the top. At the front, under a cover cap, is a socket for interconnecting the Servo EE Finder. At the back is a Single / Continuous selector switch and a small lever to operate the rewind release switch. It is only operational when the frame counter next to it is at zero. The continuous mode is only available for fast shutter speeds from 1/60 sec. and upwards to 1/2000 sec.

Because the finder is detachable, the accessory shoe is at the side, requiring special attachments. The hinged removable back is opened by pulling the rewind knob up while pushing the security lock button in front of it down. At the upper left-hand corner of the camera is the PC sync contact. There is no need for a lens release button. The lens is released by rotating anticlockwise the serrated aluminium breech-lock ring and then the lens is removed. The self-timer lever doubles as a depth-of-field preview and mirror-up control, assisted by a smaller lever for locking the first and accomplishing the latter.

The variants

In 1976 the Canon F-1n was launched with minor improvements over the original model accepting all its accessories. It distinguishes it self by having a plastic tipped lever-wind and a back-door film reminder. At the same time, the Canon FDn lensmount was presented, meant to be easier in use, while cross compatible with the earlier mounts, recognised by lacking the bright metal locking ring. This addresses the key flaw of the FD mount, the difficulty of mounting a lens one-handed. Where the original FD lenses are "breech-lock," with lens and camera remaining fixed relative to each other and te locking ring rotating around a projecting bayonet on the camera, the New FD lenses simply rotate onto the camera as any bayonet-mount lenses, with the internal mechanisms rotating to remain fixed relative to the camera.

The United States Army adopted the Canon F-1 as a standard field-issue camera as part of the Camera Set, Still Picture, KS-99C.[1]

The New Canon F-1

The New Canon F-1 arrived in 1981, introduced in March and marketed in September. It is a bit smaller than the F-1, and its two normal eye-level finders both have flash shoes on them. This, plus the lack of a mechanical self-timer, replaced with a battery cover/action grip, visually distinguish the New Canon F-1 or "New F-1," from its predecessor which does not say "New" anywhere on it. The name comes solely from the marketing, and it is not to be confused with the F-1n, which is, by contrast, almost the same camera as the original.

The New F-1 is broadly a hybrid camera: it has a shutter with a basic mechanical timer for high speeds and an electronic timer for slow speeds. Thus, the camera can be used from 1/2000th to 1/125th and also "X" (shown as a lightning bolt, equal to 1/90) and B with a dead or absent battery. With battery the shutter ranges down to 8 seconds. It is a horizontally-traveling foil shutter, as on many professional SLR's.

The New F-1 operates out of the box in both metered-manual mode (indicates the correct aperture based on current shutter speed and light readings) or aperture priority mode. The basic eye-level finder is basically just a pentaprism and eyepiece (metering is done at the side of the focusing screen) while the AE Finder FN provides the full functionality for aperture priority. (This capability is technically part of the camera, but the AE finder facilitates its use with its special meter display.) Canon notably portrayed aperture priority functionality as depending on this finder, as suggested by the manual and promotional materials, but the photographer willing to shoot somewhat blindly can use it with the regular finder. Other finders are not recommended as they let in too much light to the metering site at the focusing screen.

The AE finder has a flange which reaches out over the shutter speed dial, so that when the dial is rotated to "A" (accessible by lifting the rim up when the dial is at 1/2000th), a pin sticking up will press on a slider. This opens a flap inside the viewfinder revealing a second meter needle, this one showing shutter speeds. If the needle shows a speed within the camera's range, this is the approximate speed that the camera will employ at the moment of exposure, unless light conditions change suddenly. There is also a Judas window revealed next to this display, which, for the contemporary New FD lenses (bayonet) will show the current aperture. Older and third party lenses generally do not show up in this window.

Metering is TTL, with different patterns available through the use of different focusing screens. Precision-ground facets inside the focusing screen redirect light to a metering cell mounted horizontally next to the screen. The regular meter display with the match-needle indicators and shutter speed indicator is inside the camera body, lit by a window on top, and this shines into a special slot in the viewfinder, where a small prism integrates it into the viewfinder image. It has a galvanometer needle for the recommended aperture and a sliding ring for the current aperture, above a small window which shows the current shutter speed on a rotating disk. This whole display can be backlit with a switch on the back of the camera, which also sets the meter to stay on for sixteen seconds after the shutter release is half-pressed, with or without backlight.

The AE finder contains the needle and optics for its own aperture priority display within itself, with a window mounted high on the prism housing for backlighting. There is no electronic backlight for this display.

The camera contains many of the other standard features of a high-end SLR from the time, such as a shutter release lock, electronic self timer (both accessed by the rotating switch around the shutter release), double exposure, exposure compensation dial, battery check, exposure preview and the fittings for a motor drive.

There are two motor drives, the "AE Power Winder FN" and "AE Motor Drive FN," both of which add several features to the camera. Both have two shutter releases and single or continuous shooting modes. Additionally, both add shutter speed priority autoexposure to the camera. With the lens set to A, the camera is capable of determining the proper aperture, but not setting it. Both motor drives have a small servomotor that, when controlled by the camera, will turn a shaft on the bottom. This will mechanically set the aperture and allow shutter speed priority mode.

The "Power Winder" takes four AA batteries of any kind, is slower and does not power the camera. The "Motor Drive" is faster and takes one of several interchangeable power packs, some of which are rechargeable and one of which can power the camera via an adapter that replaces the internal battery and battery door.

The battery door is notoriously fragile, but better than the consumer cameras Canon had been putting out around the same time, such as the A-series. It is integrated into the body grip, and comes off completely when a small button on the bottom is pushed. Behind it, the compartment can take four 1.45b button cells or the 4lr44 6v piles.

The camera takes any FD mount lenses, and FL mount lenses can be used in stopped-down TTL metering mode. However, the camera was released just after the New FD or FDn line of lenses. These lenses have the aperture ring further back, where the numbers can be seen by the Judas window of the AE Finder FN. In this way Canon follows the earlier development of the Nikon AI lenses, which generally have a second aperture index in smaller letters further back on the lens to be seen by certain Nikon SLR's Judas windows. But all FD mount lenses are fully compatible with the single exception of losing one of the two in-viewfinder aperture displays. The AE Finder FN is the only viewfinder for the New F-1 where this is the case, and this is the only camera to have this issue, as no other Canon SLR used a Judas window (mechanical and then electronic displays indicated apertures on some earlier Canon SLR's, while others had no aperture display).
