Chinon CP-6
TECHNOLOGY
In 1984, Chinon introduced the world's first twin program SLR. Now again, Chinon demonstrates their photographic and electronic ingenuity by producing the Chinon CP-6 — The first camera to incorporate twin program metering, DX automatic film speed indexing and the innovative concept of spot/average metering. With the working photographer in mind, Chinon engineering produced a camera that can only be described as the ultimate in features - but easy for anyone to use - built like a Chinon.
 

 

INNOVATION

What the world needs is a sophisticated camera that takes great pictures but doesn't have to be relearned each time it's handled. The unique selection of features built into the Chinon CP-X reaches these parameters dramatically.   By utilizing three different metering modes the CP-X allows the photographer to solve any photographic situation — action, depth of focus, or total manual control of those lighting conditions that just don't come out properly without a little help from a practiced eye.4.butkus.org

AUTO FILM SPEED SETTING SYSTEM
ACTION . . . P1 THE SPORTS MODE
For most beginning photographers, pictures without blurs or camera movement are an initial goal. The P1 mode in the Chinon CP-6 camera is all that needs to be set. Shutter speed is emphasized in this mode, with a shutter speed of at least 1/60th of a second programmed into the camera right up until the lighting conditions start fading. The novice appreciates the fact that once the camera is set on P1 and the lens diaphragm is stopped all the way down, no further adjustment need be made. Conversely, the more advanced photographer uses these same exposure range-of-use settings so that he can concentrate more fully on that perfectly captured image without intermediate camera.


CHINON PROGRAM TECHNOLOGY. . . HOW IT WORKS

State-of-the art micro circuitry provides an infinite selection of shutter speeds and lens aperture combinations. When the Sports Mode (P1) is selected and the camera is coupled to a standard 50 mm F/1.4 lens, the shutter speed chosen will be 1/1000th sec. at EV 19 with an aperture seeing of F/22. As lighting conditions diminish, both shutter speed and aperture will "slow down," however the program mode will maintain the fastest possible shutter speed to minimize the effect of camera shake and provide "action freezing" photography. By comparison, on a cloudy day, the Sports Mode might select a shutter speed of 1/60 sec. with the lens aperture at its maximum opening (F/1.4) at EV 7. Should the lighting conditions fall below EV 7, the CP-6 will then convert to the Automatic Aperture Priority AE mode, providing perfect exposures as long as 8 seconds in duration.

 
CHINON "CREATIVE" P2  MODE - WHEN MORE THAN JUST "STOPPING ACTION" IS REQUIRED
Once the basics of photography are learned, the area of focus - depth of field - becomes of utmost importance to the photographer who wants total creative control of picture sharpness. 
On the CP-6 camera the P2 seeing once again permits the photographer to take his eyes off of the controls and onto the subject. As the camera controls both shutter and aperture, the emphasis now falls toward keeping the lens stopped down as far as possible. Therefore, shutter speeds will fall more rapidly to 1/8 second so depth of field will be greatest throughout virtually the entire exposure range.
 
CHINON CREATIVE MODE
The P2 chart illustrates the characteristics of the creative program. In this mode the camera first selects the optimum aperture, then selects the appropriate shutter speed to obtain a perfectly exposed picture. This preference for selective aperture provides the photographer with consistent depth-of-field emphasis without requiring any further camera control adjustments. As in the chart depicting P1 characteristics, under bright light conditions both program modes will select a shutter speed of 1/1000 sec. at F/22 under EV 19 light intensity. The difference, however, is that as the lighting conditions diminish, the P2 program will cause the aperture to remain "stopped down" as long as possible. This enables depth-of-field to remain in the program all the way to 1/8 sec. In P1 the maximum aperture is reached at 1/60 sec.
SPOT METERING - PINPOINT ACCURACY
Although, sometimes cameras seem to be able to do almost anything all by themselves this only really occurs when the picture captured in the viewfinder is placidly average. With the spot metering mode on the CP-6, a critical choice of metering can be selected with the flick of a switch.

 

 
Spot metering ignores the back ground darkness and gets the subject perfectly exposed.

 

Spot metering instantaneously increases the possibilities open to the eye and mind of the photographer. By using the spot metering mode, only 2% of the viewing area, roughly the area of the split image focus ring will be used to pinpoint the subject for concentrated exposure consideration. And, since the spot metering system works in all four exposure modes, the photographer never has to settle for "second" best when creativity is concerned.

 

 

 

SPOT METERING - WHEN YOU CAN'T SETTLE FOR "AVERAGE"
With "averege" metering, the subject is unacceptably over exposed.
Whenever lighting conditions vary greatly from subject to foreground or background, spot metering should be used to control the right exposure on just precisely the portion of the image that the photographer wants to be "on the money".  Conversely, a camera that provides only spot metering can be misdirected by scenes in which strong variations in lighting may cause a spot system to be tricked into overcompensation. In a case such as this, Chinon's CP-6 "average" metering system definitely proves to be superior.


SPOT/AVERAGE METERING - WHEN NOTHING ELSE WILL DO
There are still other lighting conditions where neither average or spot will help create a photograph, rather than merely a snapshot. With the exclusive spot/average metering mode built into the CP-6, backlighting for just the right effect is flawlessly accomplished in just one shot. Controlling lighting conditions to match the photographer's exacting eye is simple and effectively accomplished   with the Chinon CP-6. The spot/average exclusive - for when ordinary picture will not do.4.butkus.org

 

 


 

CREATIVE WITH SPOT/AVERAGE - THREE STEPS TO PERFECTION
The Spot/average mode is used in the Aperture priority AE mode. After selecting the desired aperture and placing the metering select mode in "average," the shutter release is partially depressed to activate the camera's electrical system. While maintaining finger pressure, the "M" button is touched, then released. The camera's audible tone will be heard when this command is accepted by the camera. While still maintaining pressure on the shutter release, the metering select mode is switched to "spot." The tone will again sound, indicating a light measurement in the spot mode. Within the viewfinder, three indicators will be apparent: "spot," and two shutter speeds. The blinking speed is the "average" reading and may vary as the picture is composed; the other speed is the "spot/average" speed that will be the actual shutter speed chosen by the CP-6 for the eventual exposure. Relaxing finger pressure on the shutter release or taking a picture cancels the "spot/average" mode with no memory for future photographs.

 

SPOT/AVERAGE - PERFECT BALANCE

As a rule, the spot/average mode has it's greatest advantage when a perfect exposure of a central subject will result in an overly dark or too bright background. By using this compromise mode, that optimum in-between exposure can be created with a minimum of camera manipulations.


With averaged metering, the subject is unacceptably under exposed due to the back light effect.

 

APERTURE PRIORITY AUTOMATION


 
 

AUTOMATIC APERTURE PRIORITY EASILY ACCOMPLISHED WITH THE CHINON CP-6
The automatic mode provides the photographer with a constant depth-of-field control. Simply rotate the Exposure Mode Select Dial to the "A" position and the metering mode select lever to the "average" indicator to set the CP-6 for automatic photography.
Next, select the appropriate F-stop for the preferred amount of depth-of-field necessary for the creative effect desired. The camera's sophisticated automation will precisely select the correct stepless shutter speed for a perfect exposure...every time.. With this type of creative control, the photographer may choose the exact area of the photograph to be in focus.
 

MANUAL EXPOSURE

The truly experienced photographer recognizes many situations when a manual exposure will result in a superior creative expression. The CP-6 offers a fully metered manual system that can be utilized in two ways: aperture preference or shutter preference. Both techniques start by seeing the exposure mode select dial to the "M" position. If precise aperture control is desired, the required F-stop is set on the lens. This will signal the electronics to display a glowing LED in the viewfinder.
The shutter selected by the camera will be indicated by a flickering LED in the viewfinder. Simply depress the M button to superimpose both LED's for a proper exposure. For further creative effects, you can purposely under or over expose the picture. Manual shutter preference is achieved by using the M button to first select the desired shutter speed and then rotating the lens aperture ring until the viewfinder LED's are superimposed.4.butkus.org
 
 

CHINON CP-6 VIEWFINDER... A WEALTH OF INFORMATION

The Chinon CP-6 is designed for the serious photographer, displaying all vital camera information in its big bright viewfinder.
 
1) Aperture-Selected lens seeing with automatic/manual modes.
2) Flash Ready LED - Green 1/125 sec. LED glows when Chinon dedicated flashes are recycled and ready to fire.
3) Program Mode LED - Green LED glows when camera is set to P1 and P2 program mode.
    "Program" LED flickers when lens aperture is set within four stops of maximum seeing.
4) Over Exposure LED - Red LED glows indicating too much light for proper exposure.
5) Safe shutter Speed Range - Green shutter speed LEDs indicate shutter speeds selected which do not require tripod or flash.
6) Slow shutter Speed Range - Orange shutter speed LEDs indicate slow shutter speeds selected which require flash or tripod to prevent possible subject blur.
7) Under Exposure LED - Red LED glows indicating insufficient light for proper exposure.
8) Split Image Focusing System - Used to focus vertical subjects and to make focusing with extreme wide angle lenses more convenient.
9) Microprism Collar - Used to focus subjects under low light conditions and when long
    telephoto lenses are used.
10) Ground Glass Screen - General purpose method of focusing.

AUDIBLE SIGNALS INCREASE THE VERSATILITY OF THE CP-6

In the manual exposure mode, special beep tones signal a change in shutter speed or when the aperture is set for a correct exposure. This convenient audible signal allows the photographer to obtain manual exposures without having to look through the viewfinder.
1 ) S.C.S. (shutter Change Signal) single beep will signal each time the shutter speed changes.
2) M.E.S. (Manual Exposure Signal) single beep will signal when the correct aperture is set.
 
CHINON'S HALF-MIRROR SYSTEM - FOR FULL PHOTOGRAPHIC POSSIBILITIES
The heart of the Chinon CP-6 metering system is Chinon's exclusive half mirror design. When spot metering is selected, the main half mirror transmits 15% of the total light to the sub-mirror. The sub-mirror then transmits this light to a silicon photo diode (SPD) that is located at the bottom of the mirror box. After the information is accepted by the camera's computer, the mirror proceeds up out of the way of the light path and a perfectly spot metered image


ELECTRONIC FILM SETTING - ONE LESS POINT TO REMEMBER
With less settings to be made before or during shooting, more valuable time can be spent creatively. By incorporating an automatic film speed indexing system "DX" all film cartridges having DX markings will electronically set the proper ISO from 25 all the way to 5000. Naturally, the CP-6 owner will want to override the exposure system on occasion. Built into the film speed dial is a two stop override system that permits creative exposure effects while utilizing the CP-6's incredibly accurate TTL metering system.
 



FLASH PHOTOGRAPHY— INNOVATIVE AND TROUBLE FREE
The Chinon CP-6 can use any of five automatic dedicated strobe units for electronic flash photography. The top of the line S-480 offers a "Pro-Style" bracket, LED readouts and five automatic flash ranges. Each Chinon flash offers electronic dedication for proper flash synchronization. 
Once the exposure mode select dial is set to "A" and the aperture set according to ISO and power range, the CP-6 will indicate when the flash is fully recycled by a flashing LED in the camera's viewfinder. Also, if the flash should not be completely recycled, either the aperture preferred AE selection or the pre-selected manual exposure seeing will be used rather than taking a flash picture with less than a fully recycled flash unit. Both the CP-6 and all of the flash units can be set manually for even the most demanding lighting situations.

UNLIMITED MULTIPLE EXPOSURE CONTROL
Multiple exposures with perfect frame to frame registration are made easy by the CP-6. Just slide and hold the multiple exposure lever to the left during film advancement.
 

ELECTRONIC SELF-TIMER

Be part of the creation of memories! Simply slide the selt-timer switch to the on (up) position, then depress the CP-6 shutter release. The cancellable electronic self timer delays shutter release for ten seconds. By pushing the self-timer switch to the bosom position, the CP-6's audible warning tones can be silenced.

 

BODY POWER SUPPLY CONTACT

When the optional Chinon Power Winder is coupled to the CP-6, the camera's power is supplied from the Power Winder by a unique electronic Body Power Supply Contact. No bakeries are then required in the camera body. This exclusive power source concept ensures extended power supply.
 
DETACHABLE POWER GRIP/BATTERY CONTAINER
The CP-6 body grip, not only supplies power to the camera, but also provides additional handling stability. Since it is detachable, it can be easily removed when the camera is not in use. In addition, it eliminates accidental bakery corrosion.

MULTI-SLOT NEEDLE FOR EASY FILM LOADING

Film loading is fast and foolproof with the CP-6's multi-slot needle film loading reel. The positive film loading system securely fastens the film the first try, allowing the film to be loaded easily and with confidence.
 


BULB PHOTOGRAPHY (TIME EXPOSURES)
WITH ELECTRONIC AUDIBLE TIMER SIGNAL


Just turn the exposure mode dial to the "B" position for bulb (time exposure) photography. The CP-6 is designed with a timer signal that beeps to indicate the exact time period the shutter remains open.


EXPOSURE  COMPENSATION
When deliberate over or under exposed effects are desired the Chinon CP-6 can be adjusted up to 2 full stops in 1/3 EV increments. Simply pull out and turn the film speed dial and set it to the desired exposure compensation position. 

Primarily intended for general photographic techniques, this compensation feature is invaluable when creating spectacular effects with the built-in multiple exposure lever on the CP-6. This simple feature will make you a master of light control.
