Other Functions   CLICK HERE TO SEE CUSTOM FUNCTION 1     CUSTOM FUNCTIONS 2

This camera is provided with five custom functions which are described in the table below. The camera functions are set to standard mode when shipped (setting "0"). (Operations described in this instruction manual assume that the camera is used in standard mode ("0"). When changing the custom functions, see section, "Setting the Custom Functions" on page 182.

· Camera operation changes when the custom functions are set. Read through the section, "List of Custom Functions" to make sure that you use the functions correctly.

Setting the Custom Functions

1 Turn the main switch on and hold down the ISO button and the drive mode button simultaneously until the indication shown in the illustration appears on the display panel (2 sec.).

Take your fingers off the buttons when the indication (custom function setting position) shown in the illustration appears on the display panel.

2 Press the ISO button to select and display 2 the function number to be set.

· Each time the ISO button is pressed, the function numbers are displayed in the following order: 1--2--3--4--5--1 (repeating).


3 Press the drive mode button and select 3 the desired item number.

· The item number changes each time the drive mode button is pressed. Select "O" or "1."

4 Turn the main switch off to compete the setting.4.butkus.org

· The setting can also be completed by depressing the shutter release halfway or by leaving the camera idle for 16 seconds

This socket is used for connecting cable switch L or Auto Bellows to transmit electric signals from these accessories to operate the shutter.

· During shooting using cable switch L, stray light may enter the viewfinder eyepiece and affect exposure since you cannot keep your eye at the viewfinder. To prevent this, attach the eyepiece cover over the eyepiece (see page 22).

· Do not connect cable releases sold on the market to the release socket as this may damage the socket.



Detaching the Back
It is possible to detach the camera back and replace it with an optional Data Back D-9 (see page 212). The camera back can be removed by pushing down the camera back release pin.



Aperture Stop-down Button
The lens will always remain wide open to provide a clearer view through the viewfinder. However, it can be stopped down to your desired aperture by depressing this button (the image in the viewfinder will become darker accordingly) to check the depth of field or the blurred effect on the background.

· You cannot get correct exposure when taking pictures or checking exposure with the aperture stop-down button.

BASIC PHOTOGRAPHIC CONCEPTS

<Exposure> Lighting to film. When a picture is taken, the aperture value and shutter speed adjusts the amount of light to the film.

<Shutter speed> The shutter in the camera controls the amount of light that reaches the film by the length of time it stays open. The time the shutter stays open is the shutter speed.

< Apertures Value> The aperture in the lens controls the amount of light going through the lens by becoming smaller or larger. The size of the opening produced by the size of the aperture is the aperture value.

< Film Speed (ISO Value)> Film speed is measured by values determined by ISO (the International Standardization Organization). A small ISO value means lower sensitivity but finer grain and higher image quality. A large ISO value means high sensitivity. Such films can be used in locations with poor ambient lighting or with fast shutter speeds, but it has coarser grain and therefore poorer image quality.


< Depth of Field> 

When a subject is in focus, not only the subject itself but also some area in front and behind the subject will also be sharp. The range between the nearest and farthest points that are sharp is the depth of field.

(1) The depth of field increases with small apertures and decreases with large apertures. 
(2) The depth of field is larger for a distant subject and smaller for a near subject.
(3) The depth of field is larger behind than in front a subject in focus. A lens with a long focal length (telephoto lenses) have narrower depth of field than a lens with short focal length.

The depth of field scale on a lens tells us the depth of field that it provides. For example, if we focus a 50mm F1.4 standard lens on a subject 2 meters away and use an aperture of F16, the distance indicated by depth of field scale 16 shows that we obtain a depth of field from 1.4 m to 5 m.

Camera Care and Precautions

· To remove dust and dirt on the lens and viewfinder glass, blow off with an air blower or wipe gently with a soft lens brush. If they are soiled with fingerprints, wipe off lightly with lens tissue. That is enough. Never use a bomb type blower. With its air pressure, dust and dirt may get farther into the camera interior. Wipe off dust and dirt on the minor lightly with a lens brush

· To clean the camera exterior, wipe with the soft cloth. Never use benzene, thinner or other solvents.

· After taking pictures in a dusty place such as at the seaside or on mountains, clean the camera thoroughly. Salt air will cause corrosion and sand and dust will adversely affect the internal precision parts of the camera.

· Do not leave the camera in hot places (on an ocean beach in summer, in a parked car under direct sunlight, etc.) for a long time, because the camera, film and battery may be adversely affected.

· The lens and viewfinder may be clouded if the camera is brought into a warm room from outside where d is cold. This cloudiness will disappear soon, but it is always advisable to avoid sudden temperature changes because water droplets will cause internal corrosion.

· If you are going to use the camera for important events such as an overseas trip or wedding ceremony, be sure to test it beforehand to make sure it functions properly. It is also advisable to bring a spare battery with you.4.butkus.org

· Because the camera is a precision device, do not expose it to excessive shock such as by dropping, etc.

Note on the Shutter Curtain: The shutter curtain is made of a very thin material. Never push it with a finger, or touch or wipe it. When changing film, take care that the film edge does not touch the shutter curtain. When using an air blower, do not blow air strongly on the curtain because it may be damaged or deformed. Never use a pressurized blower.

Microcomputer Protection Circuit: This camera incorporates a safety circuit to protect its microcomputer against strong external static electricity. Though rarely, it may fail to function because this safety circuit has come into action. In this case, set the main switch to OFF, remove the batteries, reload them and use the camera again.

Optional Accessories
The TLA360 is a clip-on type TTL direct metering auto-flash unit with power zoom and guide number 36 (with 35 mm lens, square cover and ISO 100). Equipped with the automatic flash setting feature, the TLA360 can offer the following four functions in combination with Contax Aria.

· These functions can be used when the flash unit is directly attached to the accessory shoe on the camera top. The flash system is not automatically set when it is used off the accessory shoe and through the TLA extension code or TLA lighting system.

<2. Flash Unit Light Compensation>
Light compensation can be used only in the ""TTL auto flash" mode and in no other mode.

· Compensation is activated in 1/3 steps in the range of -3EV to +1 EV.
· The compensation amount of the flash unit is determined by the value of the camera's exposure compensation. For example, if the camera's compensation is "+1 " and the flash unit's compensation is "+1", the amount of light from the flash unit is set to +2 (EV).


1 Press the "SEL" button of the flash unit.

· The compensation scale appears on the display panel of the flash unit and the "+/-" mark starts to blink.

2 Press the "" and "" buttons of the flash unit to set the desired value.


Press the ""SEL"" button again. The "+/-" mark changes from blinking to steady lighting and compensation is completed.

· The compensation scale of the flash unit's display panel indicates the value set on the flash unit.
· When the compensation amount of flash unit is "0" (no compensation), the compensation scale will disappear in 8 seconds.

<3. Auto OFF and Auto ON> When the power switch of the flash unit is set to "Auto OFF", the flash unit is automatically powered off approximately 80 seconds. Also, by depressing the camera's shutter release halfway, "Auto ON" is activated to start charging of the flash unit. This power saving feature is useful during prolonged flash photography.


<4. Shoe Stopper> 
The "mounting leg" of the TLA360 has a shoe stopper (slip off protector) to prevent the flash unit from slipping off the camera unintentionally. Before mounting or removing the flash unit, never forget to line up the mark on the shoe lock ring index with the mark on the "mounting leg".


 The TLA360 has a great number of functions in addition to those mentioned above. Refer to the TLA360 Instruction Manual so that you will be able to avail yourself of all l the functions it provides.4.butkus.org


Conatx Data Back D-9 (multi-function type)
This multi-function data back can be used in place of the Contax Aria camera back. It has a "collective imprinting function that can imprint exposure data on shooting on the first two frames of the film and a "between-the-frames" imprinting function that can imprint dates and exposure data between the frames. Because both functions can be used together, it is possible to record exposure data by setting the "collective imprinting" function and record dates, time or counter data between the frames so that they can be extensively used for classification of photos, storage and arrangement of exposure data, etc.


It also has an interval shooting function for controlling camera operation.

· Note that the D-9 Data Back cannot imprint on the frames itself.


Collective Imprinting Function>

Exposure data on shooting of each frame are recorded by the camera and these data are imprinted collectively on the first two frames when the film is rewound.

* Imprinted data - CLICK HERE TO SEE RESULTS

(1) Date of film loading (year, month, day and hour)
(2) Camera used "AR"
(3) Exposure data (exposure compensation value, shutter speed, F-number, exposure mode) 
(4)Frame No. (every five frames)
(5) Date of film rewinding (year, month, day and hour)

< Between-the-frames imprinting functions - CLICK HERE TO SEE RESULTS
It is possible to choose one of the following eight modes and imprint data between film frames.

(1) Date (year, month and day) 
(2) Date (month, day and year) 
(3) Date (day, month and year) 
(4) Hour (day, hour and minute) 
(5) Exposure data on shooting (exposure compensation value, shutter speed, F-number, exposure mode or two characters) 
(6) Counter data (4-digit add-up counter + exposure counter ) + two characters 
(7) Desired 6-digit fixed number + two characters 
(8) No imprint


< Internal shooting > The interval shooting function makes it possible to take automatically the set number of pictures at the set interval, starting from the set time. It is convenient for observing changes with time or unattended shooting.

Contax Power Pack Adaptor GP-1

This adapter connects the Contax Power Pack P-8 (optional accessory) to Contax Aria. The P-8 is an external power supply which uses four 1.5 V M-size alkaline batteries or four 1.2 V M-size Ni-Cd batteries. In order to prevent the battery deterioration due to cold weather, the power pack is used to keep the camera power supply warm.


· Installing the Power Adapter

1 Install Power Pack Adapter GP-1 in the 1 camera. Remove the lithium battery in the camera and install GP-1 instead.

· Store the battery compartment cover in a safe place.

2 Load batteries in the Power Pack P-8.

(1) Insert four type M batteries in the supplied battery case according to the symbols in it. Install the battery case in the Power Pack P-8.
(2) Put the Power Pack into the jacket (case).

3 Insert the Power Pack P-8 plug into the power socket of the adapter GP-1.

· It is advisable to protect the Power Pack under your coat or jacket when you are taking pictures in cold weather.

· When changing the batteries, do not mix different batteries or used batteries with new ones. Replace all the four batteries with new ones of the same type at the same time.

There are four interchangeable focusing screens for Contax Aria: FU-3, FU-4, FU-5, and FU-6. The screens have a 5 mm diameter circle in the center marking the spot metering area (FU-3 and FU-4 have a microprism as well).4.butkus.org

· Never touch the focusing screens because they are machined to very high precision.

FU-4 (horizontal split-image/microprism screen): This screen is provided as standard on the Contax Aria. This screen enables you to focus using a center split-image spot, microprism collar around it, and a surrounding matte area making it suitable for a wide range of subjects.

FU-3 (45° split-image/microprism screen): Essentially the same as the FU-4, this screen has a 45° split image center spot ideal for focusing images with horizontal lines since you do not have to tilt the camera.

FU-5 (matte screen): This screen consists of a matte area all around and is suited for a relatively narrow-aperture lens such as a long-focus lens. It is also suited for close-up work and other situations when it is difficult to focus with a microprism or split-image spot.

FU-6 (sectioned matte screen): It has ruled lines at 6mm intervals on a matte screen and is especially suited for taking pictures using perspective control with Auto Bellows or PC Distagon or when it is necessary to precisely determine a composition during copying work, etc.


< Replacing Focusing Screens >

Each screen is supplied with a pair of tweezers that should be used when screens are replaced.

The procedure described here for replacing focusing screens differ from that given in the FU Focusing Screen instruction manual. Use the procedure given below to replace focusing screens.

1 Removing the Screen

(1) Dismount the lens and gently push the screen release claw with your finger tip. This causes the screen and its frame to come forward. Gently lower the screen.
(2) Grip the protruding part of the screen with the supplied tweezers to remove it.
(3) Place the removed screen in groove of the case to protect it from dirt and damage.


2 Mounting the Screen
(4) Hold the protruding part of the screen with the tweezers and insert it in the lowered frame. Then gently push tab of the frame (release claw) with the tweezers until it locks with a click. Finally, tap it with a finger to make sure the screen has been properly seated. This completes the mounting process.

· When replacing the focusing screen, always use the supplied tweezers to prevent the mirror and screen against scratches and fingerprints.

· If the screen is soiled by dust, use a blower or soft lens brush to remove dust.

· If the screen is improperly mounted, it may come loose during shooting or it may become impossible to remove it. Should this happen, consult your nearest service station for proper handling.

· Unused screens should be stored in the screen case according to the instructions on the case.

Those who are nearsighted or farsighted and have difficulty viewing the viewfinder can obtain optional diopter lenses that can be mounted in the viewfinder eyepiece. Eight diopter lenses in the range from -5 (D) to +3 (D) are available.
