introduced 1999 - discontinued 2002

Replacement for the EOS 500N. Focusing points are increased from 3 to 7, and metering zones from 6 to 35. Film transport is faster, and there is a dedicated button for depth-of-field preview. Likely to take over from the EOS 500N as the world's best-selling single-lens reflex camera.

Partial metering is set in the Program Image Control (PIC) modes (except A-DEP) and during AE Lock.
Metering is activated when the shutter button is partially depressed, and continues for 6 seconds after the shutter button is released.
Incorrect exposure is indicated by a 'blinking' display on the external LCD and in the viewfinder.
Shooting modes:
• Intelligent Program AE (shiftable)
• Shutter speed-priority AE
• Aperture-priority AE
• Full Auto
• Program Image Control (Portrait, Landscape, Close-up. Sports)

Canon extends 3 series two new models

Choosing a new EOS camera has just become more difficult. Two new cameras from Canon update and improve existing models, making the choice of an entry-level camera less clear cut.

For nearly four years, Canon's basic SLR model has been the EOS 5000. This offered good value at under 200, but was an automatic-only camera. You could choose between Full Auto, shutter priority and four image control modes ? but there was no manual shooting mode, and no aperture priority mode. For this reason, we were hesitant to suggest it as an entry-level camera ? anyone who became enthusiastic about photography would probably want to change to a more advanced model within a few months.

Now the EOS 5000 is being replaced by the EOS 3000 ? a camera we will be happy to recommend as a first-class entry-level budget model. The EOS 3000 has a complete range of shooting modes, including manual.

What Canon has done, in fact, is to give the EOS 3000 a specification similar to that of the EOS 500, which was the world's best-selling SLR camera between 1993 and 1996.

The EOS 500 was replaced by the EOS 500N, which introduced a 'retro-style' facelift, and a few new features. However, the EOS 3000 is now snapping at its heels in terms of specification. To overcome this situation, Canon has introduced the EOS 300.

The EOS 300 has been designed as the leading AF SLR in its class, and we expect it to take over from the EOS 500/500N as the world's best-selling SLR camera.

Where does this leave owners of earlier EOS cameras? If you have an EOS 500 or 500N, there are some attractive new features on the EOS 300, but you are probably dreaming of an EOS 50 or 50E ? or even the EOS 3 ? as your next model.

EOS 5000 owners who want an expanded specification should certainly consider the EOS 300 ? they are unlikely to be disappointed.

If you want to replace the EOS 5, it is a small step to the EOS 50E, but you would do well to consider the EOS 3.

If you are ready to change an earlier camera, such as the EOS 1000, 100, 10, 600, 620 or 650, the EOS 300 will give you similar or better features in a smaller, lighter body.

EOS 300
The EOS 300 design is based on previous models, but is smaller than the EOS 500N, which it will eventually replace.

A major feature is the new CMOS autofocus sensor. This provides seven focusing points ? five laid horizontally, with one above and one below the centre point. This compares with only three focusing points on the EOS 500N. The AF speed is similar to that of the EOS 50E.

You can leave the camera to select a focusing point automatically (usually the point covering the nearest part of the subject), or select any one of the seven points manually.

Another achievement for Canon is the reduction of the viewfinder blackout time from 400ms on the EOS 500N to 250ms on the EOS 300. (This blackout occurs during the exposure and is the result of the reflex mirror moving out of the way to let light through to the film.) This advance will be barely noticeable when you use the camera, but shows that Canon is making improvements in all areas.

Other improvements include:
• 35 metering zones (6 on 500N)
• Shooting speed of 1.5fps (1fps on 500N)
• Film loading prewind time of 7.5 seconds (9 seconds on 500N)
• Midroll rewind has its own dedicated button (required Command dial and button operation on 500N)
• Depth-of-field button (not available on 500N)
The overall result is another outstanding camera to see Canon into the 21st century. 

18th February 1999

Canon introduced the EOS 300 SLR camera

Canon has added the high performance ultra-compact EOS 300, with a stylish silver two toned body, to its popular EOS range of SLR cameras.

Offering attractive features such as seven focusing points, improved AF speed, 35-zone exposure sensor, 1.5 fps film advance, shorter prewind time, midroll rewind button, depth-of-field preview and shorter view finder blackout time (approximately 250ms).

The EOS 300 is on a par with other highly specified SLR cameras in its class.


Similar to the EOS 3 the EOS 300 uses a newly developed CMOS sensor and features seven focusing points of which five are in a horizontal line across the centre of the frame with one above and below the middle point, which uses a high performance cross type AF sensor, this enables the camera to focus on off centre subjects. Point selection is automatic, with the camera using an intelligent system to select the most appropriate focus point. The focusing point can also be selected manually, which is useful when there are multiple subjects in the viewfinder and the photographer wants to emphasize just one of them.

An in-focus indicator is included on the viewfinder and an audible AF confirmation beeper is selectable from the LCD panel. The beeper can be enabled or disabled in all picture-taking modes.

Two focusing modes are available –

One shot AF and AI servo with predictive AF.

One shot AF focuses the lens and is ideal for static or slow moving objects. For action photography the camera senses the subject is moving and switches to AI servo.

The camera will then follow the subject and anticipate its position at the movement of exposure. Manual focus is also possible.

Automatic Exposure

Exposure metering is performed using a 35-zone silicon photocell (SPC) sensor. Three different metering modes are available.

Evaluative metering takes readings from the 35 different zones of the frame and compares the results with built-in pre-defined patterns. In conjunction with the focusing points the camera detects difficult lighting situations, or other difficult subjects and adjusts the exposure accordingly.

Partial metering takes a reading from an area occupying approximately 9.5% of the viewfinder. Readings can be taken from the central 9.5% reading of the picture only.

Centre weighted average metering takes readings from the entire picture area, but gives a greater emphasis to subjects in the centre.

The EOS 300 has a 3-zone built-in retractable E-TTL autoflash (GN.12m) with a 28mm flash coverage. This is linked to the multiple focusing point, when the flash pops up the red eye reduction mode is activated. In addition the camera can be used with any of the Canon EZ speedlites for accurate versatile A-TTL flash photography.

Auto Exposure Bracketing

In difficult exposure conditions, Auto Exposure Bracketing (AEB) allows the taking of three shots at different exposures, either individually or continuously.

The exposure varies to ensure that at least one shot will give the required result. When the self-timer is activated, the three bracketed shots will be exposed continuously after the self-timer delay.


The EOS 300 features a shutter with a top speed of 1/2000 seconds. The slowest speed that can be is 30 seconds – long enough for most night scenes.

In the shutter priority, and manual shooting modes, the speeds can be set in 1/2 step increments.

Designed for easy use the EOS 300 measures only 140(W)x90(H)x58.5(D)mm and weighs only 350g. It has an easy to use control dial and clear bright viewfinder, making it appealing to the new SLR photographer and experienced amateur.
