Focusing with EOS-1N

Introduction:-In 1987, Canon unveiled an autofocus (AF) EOS-650 camera that focused automatically on single central points (range points) in the viewfinder. In 1990 and 1992, with the début of this EOS-1N, Canon leads with three-point (central horizontal-axis direction), five-point AF and even an eye-controlled autofocusing, respectively. Then, with the Canon EOS-3 of 1998, the Company has developed a single-lens reflex (SLR) camera with the most sophisticated AF system, with 45-point area AF covering a wide range of 8mm x 15mm. So, above outlined a brief road map of how autofocusing technology being progressed; the Canon EOS-1N, spearheaded the second generation of AF system, was genetically designed as a high performance autofocus film-based camera, but it does manual focusing as well. Autofocusing has been the dominating the attention of manufacturers since the 1987 and has enjoyed a product cycle of approx. 10 years before digital imaging slowly taking over as the current trend. However, you can say the autofocusing technologies deployed has come to stage of maturity as over the last decade, various possible forms and designs have been tried and has received varying degree of success and failure commercially (such as brief period of lens-only AF, first generation body integrated AF, lens and body integration, or via Teleconverter enabled AF, as well as moving AF mechanism within the camera body to permit manual focus optic to be transformed into AF etc.).

From the perspectives of design, performance and commercial applications, the combination of Canon's EOS with EF AF-concept has proven to be the most successful among all prevailing options, even today. Some of the most advance AF technologies were also by them, for instance, evolved from the basic theory, Canon invented and developed the first eye - controlled auto - focus technology as well as 45-points AF selection in the world etc. I am not sure if sections that follow will benefit any current Canon users as some may term them as plain, simple (or even boring to go back reviewing technology a decade ago) but to potentially a new user who is migrating from manual focus era to AF, new "deflected" users from other system label(s) or simply someone who has just acquiring an used Canon EOS-1n, the content posted here may prove to be useful. Digest as much as you can, modern SLRs are very much different old days of electronic cameras. Well, as SLRs are ain't cheap as the old days, as long as the my main objective of creating the site is served, it is a consolation for me; if not, just let the content be served as an archive, chronicles another favorite Classic SLR camera of modern times.

The autofocusing section in this Canon EOS-1N site consists of TWO components. The basic for users who has just acquired the camera and next, technical information for hose who wants to go one step beyond in the operation. Depends on priorities, you may choose to ignore one or skip to next section.

Although there are plenty of technology behind, but they are not visible and autofocusing has been designed in simplest form in its operation. After turn on the camera (rear, bottom, center); lightly pressing the shutter button halfway activates autofocusing as well as its AE metering and displays relevant information relates to exposure and focusing. The exposure setting is shown on the viewfinder and LCD. As a focusing point achieves focus, it flashes red and the green in-focus indicator lights. when pressed the shutter button halfway, AF and AE are both activated. There are TWO selections in autofocusing, the One-Shot AF mode is default setting, one of the FIVE focusing point which achieves focus will flash in red and the in-focus indicator lights (exposure is also set, then shown on the LCD and viewfinder). After the button is released, the exposure information remains displayed for 6 sec. When the One-Shot AF mode and evaluative metering are set, press the button halfway to lock the AF and AE. Then release it and press it halfway to focus and meter the scene anew. When you prefer the alternate AI Servo (continuous shooting) AF mode, pressing the shutter button halfway won't lock the AF and AE. They track the moving subject until the shutter is released. Press the button fully to release the shutter and advance the film after exposure.

Differences between the two AF modes ? If you don't have the patience to go through sections that followed, A simple explanation:is - One Shot AF will only release the shutter when focus is achieved, Continuous (AI-Servo) mode will release the shutter regardless the focus is achieved or not, although Canon makes sure it, it is used for action flow on rapid shooting sequences. The third option other than autofocusing is, manual focusing. Next, after determine the AF modes (One shot, AI Servo or manual); the next is to pick up some skill in manipulating the FIVE focusing points for wide area selections provided instead of always fall back to a sole, dead center selection. There are two ways in altering the preferred area out of the five focusing point selections.

The Canon EOS-1N five AF selection points   Note: - Actual shown selection on the top LCD panel is not shown in red. It is coloured just for illustration purpose only.
Turning the main dial selects the focusing points in the following order: automatic focusing point selection (all five focusing points are displayed) . far left . left center . center . right center . far right.

1. Press the focusing point selector AF_5 focusing points.gif at the top rear section of the camera. The current focusing point will then light in red on the viewfinder screen. It will also be indicated on the LCD. 2. Turn the Main Dial until the desired focusing point lights up. To set the focusing point selection to automatic, turn the Main Dial until all five focusing points light up. 3. Press the shutter button halfway or wait 6 sec. so that the selection is set. Another way for focusing point selection is, with Custom Function No. CF-11 set to "2," turning the Quick Control Dial makes selecting a focusing point instantly.

(1) On the camera back, press the focusing point selector AF_5 focusing points.gif, when the button is released, the LCD will display the current mode for six seconds. Turn the Main Dial to select the desired focusing point. To set the focusing point selection to automatic, turn the Main Dial until all the focusing points light up. The focusing point can be selected manually or automatically to suit the user's preference and shooting situation. To select the focusing point manually:

(2) The Quick Control Dial can also select the focusing point. Set Custom Function No. CF-11 to "1' select a focusing point by pressing the exposure compensation button and turning the Main Dial. Set the Function to "2," i.e. 1 ~ 2; select a focusing point with the Quick Control Dial or by pressing the exposure compensation button and turning the Main Dial. To take full advantage of five focusing points, quick selection of a focusing point is important. By setting Custom Function CF-11 to "2," you can quickly select the focusing point by using the Quick Control Dial. When a focusing point is selected, it lights up on the viewfinder. You can also turn the dial to select a focusing point during continuous shooting in the A] Servo AF mode to track a moving subject. Can the focusing points be invisible ? yes.
Custom Function F10 prohibits superimposed focusing points in the viewfinder.

Other info relating to Automatic Focusing Point Selection Mode
Section 1
The camera automatically selects an individual focusing point after evaluating all 5 points simultaneously.
Section 2 In One-shot AF mode, the system usually gives priority to the closest reliable subject.
Section 3 In AI Servo AF mode, the system always gives priority to the central (cross-type) focusing point for the first exposure

AF Point selection sequence 1 AF Point selection sequence 2 LCD Custom Function no. 2   Note: -When Custom Function No. CF-11 is set to "1' or "2," the focusing point selector functions as an exposure compensation button. In effect, the functions of the focusing point selector and exposure compensation button are reversed.

AF Point LCD panel selection
Confusing ? don't be. If you are still fresh with your EOS-1N camera, just use the default setting first, i.e. One Shot AF, and revert back to Press Focusing Point activated button at the back and use the main dial to turn for the selection. Worst still, use back dead center selection. This section is good when you have accidentally shifted the focusing point and wish to reset it back to any point you like. Although looks complicated via reading these paragraph, in practice, it is relatively a easy process. The only issue you need to remember is, to set the focusing point selection back to automatic, turns the Main Dial until ALL the focusing points lights up.
