The camera's features are as follow: A. Features around the Camera at the Rear Section

Main (ON/OFF) Switch One of the rather odd design of the Canon EOS-1 Series bodies is the location of the ON/OFF switch of the camera, where it is located at the bottom rear section of the camera. In fact, from a recent observation where I handed a EOS-1N to a staff of mine to toy around with, the more prominent Quick Control Dial Switch was the first that he tried to turn on the camera. But this is not a big issue, just a little comment where I thought by simply prints the "icon-lockRed.gif" (or reverted by using a universal straight forward name like "ON / OFF " will solve this issue. This camera is an ALL electronic camera and it requires battery power ALL operation which includes ON the camera; so, just ensure it is loaded with necessary power source before turns on the camera because it will not react either. The main switch has three settings, as described below:

ON/OFF Switch   The power is off and the camera does not operate. Set the main switch to this position when not using the camera. Setting the switch to prevents unintentional power drain which can be caused by objects pressing against the shutter button during transport or storage.
A   Set to this position when preparing and operating the camera.
Audible Alert   This position is the same as the A position except that a beep sound is emitted when the subject is focused in One-shot AF or manual focusing mode. Note -The Canon EOS-1N RS model has a slight different configuration at this setting. The audio alert icon has been removed and replaces with "RS" Real Time setting.

Always turn the camera to "L" whenever you think you are not going to use the camera because the top LCD panel will remains active and it actually drains the power. I would think the energy management of the EOS-1N was a little weak here as auto power off to conserve power if the camera stays in a state of inactivity for 16 sec. was not designed by Canon. Anyway, looks like one just have to live with it and learn the habit of turning it off whenever it is not in use.

ON/Off Switch EOS-1N
Mid Roll Film Rewind Button

The button just next to the main switch is for
rewinding the film in mid-roll, press the film rewind button (). The film immediately starts rewinding regardless of what number you have shoot..

The button is designed in such a way that it is not easy being accidentally activated to avoid undesirable intention (may need a finger nail or sharp pointer such as pencil etc. to depress fully for activation). Note:- The EOS-N will automatically begin film rewind after each time film roll finishes and no pressing/switching of any button/lever is required, this function is only meant for specific usage). In the case when battery is weak and camera stops to react, pressing this button after loading a new battery will resume the film rewinding process as well.

Quick Control Dial on Canon EOS-1N
Quick Control Dial The uniquely innovative dial input system that makes Canon's camera different from others. In terms of its basic operation, it is the same with the earlier Canon EOS-1 and thus, owners of the EOS-1N upgrade will find it very natural to operate the camera. In many ways, you ought to use not just this dial but TWO input dials for easy and quick control of various functions. Unlike the Main Dial that sits near the shutter release button which actually making use of the pointer (finger), the rear Quick Control Dial uses the thumb to operate. It is more like a secondary feeder to the Main Dial but the thumb wheel design allows for convenient, fast exposure adjustment and/or other functions.

The quick control dial has its own On/Off switch. The rather oversized switch also has a very prominent red index dot. - by turning the switch to "O" to deactivate and "I" when need to activate.

In many ways, the Quick Control Dial is used as a complement to the main dial. For an example, when operate in Manual Exposure,it is used to set the aperture value while the main dial is used to set shutter speed. It can also be used for function(s) that normally requires an adjustment of the main dial selected function such as aperture settings when operates in Bulb mode. However, when you intend to set flash exposure compensation value(s), only the quick control dial can handle that function.

The rear QCD represents one of the most significant changes in the design of modern professional camera bodies as evidenced by adoption of similar concept by other major camera manufacturers such as the modified/evolved form used in the Nikon professional camera models such as Nikon F5. Quick Control Dial does not always included by Canon on all their film-based or even the Digital AF SLRs and it has remains as exclusively on their "high end" series SLR models.

The quick control dial is active only when the shutter button is half pressed or while the six-second timer is operating. Turns the dial off can also prevent inadvertent changes of set function such as exposure, shutter speed, or aperture settings. For some specific camera functions or adjustment of settings, both the index finger manipulated Main Dial near the shutter release button and thumb controlled Quick Control Dial at the rear section work singularly or in combination. The main aim is to enable quick, easy adjustment of various camera settings such as manipulation of focusing point(s), altering metering mode(s) and autofocus mode(s) and even changing a specific shooting mode. The custom function is also change or select by choosing the number by pressing the corresponding button). Both dials works quite similar in rotary function in exploring all possible options for a display or usage in a specific function by turning the dial on a full rotation and the cycle will begin again - except for shutter speed and aperture numbers are not subject to such a rotation. i.e. once the largest or smallest value (shutter speed and aperture) has been shown, the respective value will be shown (actually the design is corresponding with the lense type or maximum/minimum apertures of the lens in use). Lastly, the Quick Control Dial at the rear section can also be used when the flash exposure compensation is required. First, press the flash exposure compensation button and use the Quick Dial to adjust the desired compensated value.

Interchangeable Film Back The standard film back of the Canon EOS-1N is an interchangeable type. The optional Command Back E1 but lacks the great feature of the PC-interlink capability like the Data Memory Back 90 (Canon T90) which functions like a storage device for upkeep of data exposures and other features. The optional Back also doesn't has a Quick Control Dial, instead, you set the aperture by pressing the exposure compensation button and turning the main dial.

Unlike some manufacturers whose eyepiece is rounded, Canon has designed a rectangular shape which corresponds to the film format. Since the viewfinder was now a fixed type (non interchangeable - a big lost of this great feature and making the Nikon F4 and Nikon F5 as the last of such AF camera type to carry this feature, Nikon F6 has followed Canon's foot step by having a similar non-removable prism). Anyway, as Canon (as well as a few third party suppliers) offer some working solutions with Angle Finder B & Magnifier S for low-angle shots, duping, and close-up photography, this is not entirely a big issue except for specific photographic applications.

The standard film back also is equipped with a film confirmation window - a feature that actually first popularized by the P&S cameras but this seemingly amateuristic feature is very practical for SLR users in providing a quick visual check. One can always know if a film roll is installed. Although it is supposedly light-tight but for those who intends to use the Canon EOS-1N for infrared photography, one should examine or provide some form of extra precaution and/or seek other online opinions.

The viewfinder area consists of three main parts that might affect effectiveness and comfort during shooting. Except for an additional feature of the eyepiece shutter, the remaining features of built-in dioptric adjustment and the eyepiece slot to accept rubber frame is the same with the earlier Canon EOS-1.

eyecupA.jpg eyecupremoveA.jpg
Eyecup Ec II (Optional item but was supplied as standard accessory for the EOS-1n RS, it is also usable on the EOS-1). The new eyecup designed was partly due to complaints that received by Canon regarding the Rubber Frame Ec (EOS-1) to the effect the eyepiece rubber easily breaks and hard to remove from the eyepiece

This update was to patch these issues. But the improved area also has its weakness,as it is not that friendly to remove it easily either. Overall, I would rather have it securely mounted rather than a loosen frame, so, it is not a big issue. The rubber frame is useful as it helps to improve concentration on viewing and when you work with long shooting sessions, it does relieves stress by constant leeching to the hard surface, I would suggest it as a good, cheap investment.

Eyepiece Shutter

IF I can recall correctly, when the first successful Canon multi-mode auto exposure camera, Canon A1 was introduced back in 1977/8, Canon was already aware the potential problem of inaccuracy of meter reading (due to placement of the light sensors) that might affect by external strong light source. So, it was kind of strange the shutter eyepiece feature was omitted from the EOS-1 design. So, with the increasingly complex of evaluative meter plus other metering functions, this may become a necessity to minimize chances of such negative effect. So, the Canon EOS-1N now has added this feature again. By closing the eyepiece shutter, it prevents stray light from entering the eyepiece and affecting the metering. It can be affected in two ways, but most would just interrelate such possible scenario during a self-timer operation, but it also works when one tend to tilt the camera downwards with a rear section strong light source hitting the eyepiece during other types of shooting situations. For an example, time exposures in auto mode, so, the eyepiece may serve the same benefit as well.

Technically, due to the addition of the built-in eyepiece shutter in the EOS-1N, there is less space available for moving the adjustment lens than in the EOS-1 (lens movement amount: 5 mm). However, by increasing the power of the EOS-1N's eyepiece lens, the same adjustment range as the EOS-1 was achieved despite the smaller movement range. The viewfinder magnifications at the various adjustment positions are shown in below. If the user requires greater compensation than is provided by the built-in dioptric adjustment function, the Dioptric Adjustment Lenses E can be used. The adjustment range possible when combined with these lenses is -5.6 dnt - +5 4 dnt

eyepieceshutterB.jpg
The adjustment also allows near- or far-sighted users to take pictures without wearing glasses (something that others like Nikon called it as "High Eyepoint" but actually, the negative aspect was a generally smaller view field (approx. x 0.72 (-1 dpt, 50mm lens at oo) - I'd really missed the oldies large and clear viewfinder images projected by such bodies like the Olympuses or the Pentaxes ( 0.92 X ). The diopter can be adjusted within a range of -1 ~ ± 2 dpt (-3 dpt ~ +1 dpt) via the moving convex eyepiece lens backward and forward (movement amount: 3.5 mm).

diopteradjustA.jpg
Dioptric Correction Operation:- Squeeze both sides (non-slip grip sections) of the rubberized eyecup to release the hooks and slide it up to detach the eyecup first. Look into the viewfinder and turn the dioptric adjustment dial in either direction until the five focusing points or the fine spot metering area mark appear sharp or clear. The diagram shows the dial in the standard position (no compensation: -1 dpt). IF you wish, reattach the eyecup back to the camera's eyepiece. Separately-sold dioptric correction lens E (10 types in total) can be attached to the rubber frame Ec of the eyepiece and they provides dioptric adjustment from a higher density from -6 to +5 (read below for technical notes).

AE (auto-exposure) lock Button & Focusing Point Selector Button

Locating the edge of the top, rear section of the Canon EOS-1N camera, a place that one would easily has the thumb get accessed to was two buttons. The placement of the buttons also indirectly signifies their possibly frequent usage in picture control. The button with an asterisk (strange, why don't just print an "AE/AF" word instead of guess work) is for locking an exposure ("AE Lock") while the one that sits at the outer section is the Focusing Point Selection Button. In any case, both buttons are related to
autofocusing control as well as part of an exposure control and they should be featured in their respective sections but since they are located at the back, I will just scroll through them briefly one by one.

AFselectBTN.jpg
In an AE mode, the auto exposure setting can be locked temporarily in one of two ways:

1. With the One-Shot AF mode and evaluative metering set, press the shutter button halfway. When focus is achieved and the shutter button is still in the halfway position, the point of focus and auto exposure are locked simultaneously. The exposure reading is thereby set for the point of focus.

2. Alternately, you can also use the AE lock button on the rear of the camera. Pressing the button locks the exposure regardless of the shutter button operation. The AE lock button can be used with any metering mode. After locking the exposure, you can still refocus. With One-Shot AF and evaluative metering, the auto exposure setting is locked when AF is achieved.

viewinfo-AElockExpcompen.gif

Canon designed in such a way that you need not have to remove your eyes from the viewfinder. When the AE is locked, an asterisk (*) lights in the viewfinder. AE lock is canceled 6 sec. after the shutter button is released. It can be canceled immediately by pressing the AF mode, metering mode, or shooting mode selectors. AE Lock provides one of the most convenient way if you are not entirely sure and/or situations you need to react quickly to a changing situation. I would think it is a more positive way than exposure compensation which requires great deal of experience in reading/guessing what amount should be compensated. Can it works on BOTH ? yeap (see above for the changed illustration of the viewfinder info). The viewfinder will react differently as well. But unlike in flash photography, why would anyone want to do that ?

The other button with an icon icon-AFpoints.gif above, as stated, is for altering the various (one of the five) focusing point (similarly, Canon offers TWO solution in focusing point manipulation). The first method is straight forward way, on the camera back, press the focusing point selector, 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. Press the focusing point selector and turn the Main Dial. Automatic focusing point selection can also be set.



The EOS-1N has five focusing points on the viewfinder screen. The focusing point can be selected manually or automatically to suit the user's preference and shooting situation. To select the focusing point manually:

AFpoinjtBTN.jpg
1. Press the focusing point selector. The current focusing point will then light in red on the viewfinder screen (it can be disengaged, reverting back to black colour via CF setting). It will also be indicated on the LCD (the red pointer above are just for illustration, the top panel LCD will not display the AF point in red as shown above). 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.

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," select a focusing point with the Quick Control Dial or by pressing the exposure compensation button and turning the Main Dial.

reardialback.jpga
To take full advantage of five focusing points, quick selection of a focusing point is important. By setting Custom Function No. 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.

Focusing point (2) With Custom Function No. CF-11 set to "2," turning the Quick Control Dial makes selecting a focusing point instantly possible. To take full advantage of the five focusing points, set Custom Function No. CF-11 to "2." 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.

Note:- To take full advantage of five focusing points, quick selection of a focusing point is important. By setting Custom Function No. 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.
