Top professional EOS model receives more than an update

Professional photographers do not like to change their cameras every year – yet they want to be at the forefront of technology with their equipment. The only way for a camera manufacturer to overcome this dilemma is to ensure that each new professional model is sufficiently advanced to remain ‘up-to-date’ for several years.

Canon did this five years ago when they introduced the EOS 1. It is still one of the world’s leading professional cameras, and a favourite with news and sports photographers.

But the last couple of years have seen attractive new features appearing in some of the newer EOS models. Quieter operation and multipoint autofocusing are two areas which have been generating professional interest. So Canon has introduced a new EOS 1 model – the EOS 1N. This not only brings the latest technology to professionals, but also refines and improves other aspects of the camera in direct response to request from EOS 1 users. The result is a camera which is at the forefront of SLR technology, following the EOS 1 tradition, but is more than a simple upgrade.

Professional and enthusiast amateur photographers will be able to buy the new EOS 1N safe in the knowledge that it will remain a leading SLR camera for many years to come.

Here are some of the major enhancements:

5-point autofocus

Improved focusing and metering integration

Extended AF working range

Improved focus prediction and object tracking performance

Faster shooting speeds – up to 6fps with Power Drive Booster E1

Choice of five metering modes, including 16-zone evaluative metering

Three-zone flash metering linked to the focusing point

Flash compensation

Mirror lock-up

Super-quiet film rewinding

Six additional Custom Functions

Extended durability guarantee

Select the focusing point to suit the subject

The EOS 1N uses an innovative 5-point focusing system. The points are arranged in a line across the centre of the focusing screen. Each point can be selected manually. Once selected, the point appears superimposed in red over the image. Autofocusing on the point is near instantaneous.

If the subject is traveling diagonally across the frame, the Quick Control dial can provide fast manual focusing point selection to help you track the movement.

You can also let the camera select the optimum focusing point for you. The AF system will automatically evaluate the scene and determine which of the five points offers the best focus for the composition. The select point will be superimposed in red over the image.

Advanced technology gives ultra-precise focusing

The autofocusing system of the EOS 1N makes use of Canon’s latest generation Multi-BASIS (Base-Stored Image Sensor) technology. In addition to a cross-type sensor for the centre focusing point, there are two vertical sensors on the left and two on the right. This arrangement increases the focusing accuracy, as well as giving wide-area coverage. In addition, the AF system operates over light levels from EV18 to EV0. This means there are fewer situations which give focusing problems, making the overall AF performance even more effective and reliable.

Three focusing modes are available. In the One-Shot AF mode, the camera focuses automatically using the 5-point AF system. Once in focus, the AF operation stops. The shutter release is locked until focus is found, making out-of-focus images impossible.

With AI Servo AF, the camera continually refocuses as the subject moves, leaving you free to concentrate on composition and shutter release. If the subject reaches a certain speed of movement towards or away from the camera, Focus Prediction Control automatically engages. The sensor tracks the subject, assessing its speed and direction to determine where it will be at the moment of exposure. This overcomes the errors which can occur because of the slight delay between pressing the shutter release button and the actual moment of exposure.

Manual focusing is also available. With some EF lenses, there is no need to switch to a manual focusing mode – manual focusing is engaged as soon as the manual focusing ring is turned.

Shooting modes to suit every photographer

As you would expect from a professional camera, the EOS 1N offers a versatile Manual Exposure mode. You have total control over the settings, using two convenient control dials. The main electronic dial (next to the shutter release button) selects the shutter speed; the Quick Control Dial (on the back of the camera) selects the aperture. (You can reverse these settings with a Custom Function). The viewfinder read-out shows both the selected settings, together with a bar-dot display which indicates the camera meter reading and the variation from this of the manual settings.

Intelligent Program AE mode might appear to be out of place on a professional camera, but it combines ease-of-use with creative control. The program calculates and sets both shutter speed and aperture. It also takes into account the focal length of the lens being used, and increases the shutter speed for longer focal lengths. And if you want to change the selected shutter speed or aperture while holding the same exposure value (Program Shift), you simply turn the main electronic dial.

Shutter-priority AE (Tv) allows you to select the shutter speed and then sets the aperture required for correct exposure. The speed range is from 30 seconds to an impressive 1/8000 sec. Speeds can be set in increments of 1/3 stop, 1/2 stop or 1 stop (selected by a Custom Function). Aperture-priority AE (Av) is similar, except that you select the aperture and leave the camera to set the shutter speed.

If you are not sure of the aperture needed to give the required depth-of-field for your image, you can use the Depth-of-field AE mode. Here, you first focus on the nearest point you want to appear sharp, and then on the farthest point you want sharp. Then compose the picture and shoot. The EOS 1N will automatically set the best focusing distance and aperture to give adequate depth-of-field, together with the correct shutter speed for optimum exposure.

Exposure metering that leaves you in control

The EOS 1N offers several different exposure options, leaving you to choose which is best for any particular situation.

Evaluative metering is a microprocessor-controlled system that evaluates the lighting conditions in 16 different zones of the image. Each reading is compared with a library of algorithms stored in the microprocessor circuits. In this way, the camera is able to recognize spotlit or backlit subjects, and very bright or dark subjects, and can compensate accordingly.

Evaluative metering can be exchanged for Centre-weighted metering using one of the Custom Functions. Centre-weighted metering leaves the photographer to determine how much exposure compensation – if any – is needed for the scene. Photographers familiar with this type of metering from other cameras will not need to change their technique when switching to the EOS 1N.

Partial metering takes a reading from just a central section, about 9% of the total image area. This is useful when you want to base the exposure on a certain part of the subject without it being influenced by light or dark surroundings.

Even greater control is offered by two additional metering modes. Spot metering takes the reading from a small zone (about 3.5% of the image area) centred on a manually selected focusing point. Fine Spot Metering is even more precise, reading from just the central 2.3% of the image area.

A-TTL and TTL auto flash control are available when using Canon Speedlites. And with the new Speedlite 540EZ (see below), features include three-zone flash metering linked to the focusing points and an AF auxiliary light compatible with 5-point focusing.

Exposure compensation for perfect pictures

Exposure compensation is sometimes seen as a way of overcoming inadequacies in the metering system. This is rarely needed today. With the EOS 1N in particular, the range of metering options, when used by experienced photographers, means that most images should be adequately exposed. Exposure compensation is much more useful for altering the mood or atmosphere of the image.

Manual exposure compensation is possible over a range of +/-3 stops in either 1/3 stop or 1/2 stop steps (selected by Custom Function).

Auto Exposure Bracketing (AEB) is also possible. Here, three frames are exposed in rapid succession, with different exposure settings. This is very useful when you need to be certain of at least one correctly exposed image and the subject does not allow you the time to assess this accurately. Again, the exposure range is up to +/-3 stops in 1/3 stop or 1/2 stop steps. The EOS 1N also gives the choice of the order in which the frames are exposed: -, 0, + or 0, -, +.

With the Speedlite 540EZ, fill-in flash ratio compensation is available over +/-3 stops in 1/3 stop increments.

Integrated focusing and metering gives optimum results

The EOS 1N brings together the readings from the focusing, metering and flash exposure sensors to ensure the optimum results under any conditions. For example, the five central zones of the 16-zone evaluative metering system are also the locations of the five focusing points. This means that the metering system knows the position of the main subject and can adjust the exposure accordingly. In the same way, the flash exposure is also influenced by the subject position.

Canon calls this system ‘AIM’ – Advanced Integrated Multipoint control. It is another new feature of the EOS 1N that takes photographers closer to photographic perfection without intruding on creative control.

Custom Functions put you in charge of the camera

With many cameras, you have to work the way the designers dictate. This is not the case with the EOS 1N. There are 14 Custom Functions which allow you to set the camera to suit your own style. For example, you can choose whether to have the film leader inside or outside the cassette after rewinding. You can work with Centre-weighted exposure metering instead of Evaluative metering. You can stop the selected focusing point from appearing in red in the viewfinder. All this, and much more, can be set quickly and easily. No other manufacturer gives you this amount of control over your camera.

What you see is what you get

The EOS 1N viewfinder gives an almost 100% coverage, which means that what you see on the focusing screen is what you will get on the film. There is also a built-in dioptric adjustment from -3 to +1 which will appeal to photographers who wear glasses. A built-in eyepiece shutter eliminates the risk of stray light entering and affecting the exposure readings when your eye is away from the viewfinder.

Other features of the EOS 1N include:

Fixed eye-level pentaprism.

Laser-matte focusing screen with fine spot metering area mark. Seven other interchangeable screens available.

Film speed automatically set by DX coding (ISO 25-5000). Manual film speed setting from ISO 6-6400.

Automatic film loading, advance and rewind. Mid-roll rewind possible.

Battery check button.

A-TTL flash metering via hot-shoe contacts. PC flash socket also fitted.

Remote Control via 3-pin socket.

Multiple exposure facility – up to 9 exposures can be preset.

Self-timer with 10 second delay.

The quality that makes the difference

The EOS 1N is a quality camera. You only need to pick it up to feel the difference. The contoured shape is designed to fit your hand naturally, with the key controls at your fingertips. The large Quick Control Dial on the back of the camera can be turned easily with the thumb whether the camera is in the horizontal or vertical format. The large LCD panel and clear viewfinder read-out give all the information you need where and when you want it.

The camera is also quieter. Many of the noise reduction features first seen in the EOS 100 have been incorporated. The effect is especially noticeable during film rewind, where the noise level has dropped from 70dB (EOS 1) to 48dB (EOS 1N).

The body is made from glass-fibre reinforced polycarbonate resin, a material that passes the severest durability tests. A sealed cover and the elimination of external slide switches mean that it is extremely dust and water resistant; the main electronic input dial uses a ‘water wheel’ construction to scoop out any drops that might penetrate. The shutter blades are coated with a water-repellent lubricant. Double contacts are used on some of the electrical switches for improved reliability. Tests show that the EOS 1N can be used in temperatures from -20 degrees C to 45 degrees C, and at up to 85% humidity, without any problems.

A new shutter unit has been designed for the camera. It features an ultra fast top speed of 1/8000 sec, a fast flash synchronization speed of 1/250 sec. and high precision. By reducing the weight and load of the shutter blades, durability has also been improved. In fact, the improvements are so great that Canon now guarantees the shutter operation durability for 100,000 releases, compared with 50,000 releases for the EOS 1.

Faster shooting with the EOS 1N RS

In continuous exposure mode, the EOS 1N will shoot at up to 3fps.This can be increased to approximately 6fps when the Power Drive Booster E1 is attached. For even faster shooting speeds, you need the new EOS 1N RS model which fires at up to 10fps in RS mode.

This high-performance camera features real-time operation – there is a delay of only 6ms between pressing the shutter release and the film exposure. Also, the viewfinder image remains visible at all time. This is made possible through the use of a hard-coated pellicle reflex mirror. This fixed mirror reflects light up to the viewfinder, and also transmits light through to the film plane. Higher shooting speeds are possible because the mirror does not move between exposures. The fixed mirror also reduces camera vibrations and operating noise.

The constantly visible viewfinder image is very useful with flash photography. You can confirm that the flash has fired because the light can be seen though the viewfinder. You can also monitor the effects produced by stroboscopic flash photography.

The main specification of the EOS 1N RS is similar to that of the EOS 1N, but differences include:

Interchangeable focusing screens must be fitted by Canon Service facility

AI Servo focusing is automatically switched to One-shot in RS mode

Depth-of-field mode not available

Auto Exposure Bracketing cannot be set or used in RS mode

Professional accessories to match the camera

Introduced with the EOS 1N are a number of new EOS system accessories. Most of these can be used with other models in the EOS range, but several will be of particular interest to professional and enthusiast photographers.

The Speedlite 540EZ is a successor to the Speedlite 430EZ and includes the following main improvements:

Increased power – maximum guide number is 54 (ISO 100, m)

Increased zoom range – from 24mm to 105mm

Increased wide-angle coverage – 20mm with built-in diffuser panel

Increased low power manual firing range – 1/1 to 1/128

Bounce head can be tilted 7 degrees downwards

Multi-firing frequency increased up to 100Hz

Number of multi-firings can be set between 1 and 100

Auto flash exposure check after shooting is now available

AF auxiliary light is compatible with 5-point AF system of EOS 1N

SE (Save Energy) function can be cancelled

Larger LCD panel for easier readability

Faster recycling when external power source is used

The Speedlite 540EZ joins the recently-introduced Speedlite 480EZ, giving professional photographers the choice between shoe-mounting (540EZ) and side-mounting (480EZ) units.

The new Wireless Controller LC-3 Set extends the range of remote photography with EOS cameras to 100 metres, or more. The Set contains two units, a Transmitter and a Receiver. The Receiver is connected to the Remote Control socket of the camera and can be shoe- or side-mounted. The Transmitter not only fires the shutter from a distance, but also allows you to select single-shot or continuous firing. A unique feature is the inclusion of a Remote Socket on the Transmitter. This allows the Receiver to be connected to the Transmitter as an intermediate station to double the range of the remote system to 200 metres. In theory, an unlimited number of Receiver/Transmitter pairs could be set up to extend the range over any distance. Both units are also fitted with PC (coaxial) flash sockets. This allows the Receiver to be used as a slave cell to fire a remote flashgun, triggered either by another flashgun, or by the Transmitter.

The ExtensionTube EF12 extends Canon’s range of EOS close-up accessories. Apart from the length, the basic specifications are similar to those for the Extension Tube EF25. With the EF 50mm f/1.8 II lens, the magnification range is increased to 0.24-0.39x.

Type AA Battery Pack BP-E1 has been introduced in response to requests from EOS 1 users for an alternative power source to the 2CR5 battery. Type AA batteries can be used with the Power Drive Booster E1, but this is bulky and heavy for users who do not want the increased motor drive speed. The new Battery Pack BP-E1 is a more compact grip which can house both AA-size batteries and a 2CR5 battery. The AA-type batteries can be alkaline-manganese or rechargeable Ni-Cd. A changeover switch allows either the 2CR5 battery or the four AA-type batteries to be used. The Battery Pack BP-E1 can be used both with the EOS 1 and EOS 1N.

Last, but not least, is the Standard Eyecup EC-II. This overcomes the problems of using the Eyecup EC on the EOS 1. It is made from a more durable synthetic rubber and the shape has been changed to increase its useful life. The mounting method has also been modified to improve ease of handling. The Eyecup EC-II is suitable for both the EOS 1 and the EOS 1N.
