Frequently Asked Questions - Canonet CANON

How do I load film into the Canon Canonet?

To load film, open the back cover, insert the 35mm cartridge into the left chamber, pull the leader across to the take-up spool, and advance the film using the film advance lever until the sprockets engage. Close the back and advance again until frame 1.

What type of battery does the light meter require?

The Canon Canonet typically uses a PX625 mercury battery (or modern equivalent LR44/SR44 with an adapter). Note that mercury cells are obsolete; use alkaline or silver oxide alternatives, but exposure may need adjustment.

How do I set the correct exposure?

Set the ASA dial to your film speed (e.g., 100 for ISO 100). Then look through the viewfinder and adjust the aperture ring and shutter speed dial until the light meter needle centers in the window. This indicates proper exposure.

Why is my light meter not working?

The selenium cell may be dead due to age. The Canon Canonet's light meter relies on an unpowered selenium cell; if the meter does not respond, it may need repair or replacement by a professional. Alternatively, meter externally with a handheld meter.

How do I rewind the film after finishing a roll?

Press the rewind release button on the bottom of the camera, then turn the rewind knob clockwise until you feel a slight tension release. Open the back carefully to remove the cartridge.

Can I use modern 35mm film in the Canonet?

Yes, the camera accepts standard 35mm film in DX-code cartridges. However, the Canonet does not read DX codes, so you must set the ASA manually. Use films like Fujicolor or Kodak Portra.

How do I clean the lens?

Use a blower brush to remove dust, then gently wipe with a lens cleaning solution on a microfiber cloth in a circular motion. Avoid touching the glass with fingers.

What is the self-timer and how do I use it?

The self-timer is a mechanical lever on the lens barrel. Pull it down and release; it will delay the shutter by about 10 seconds. Use it for self-portraits or to avoid camera shake.

How do I store the Canonet when not in use?

Keep the camera in a dry, cool place away from humidity. Remove the battery if present. Store with the lens cap on and the shutter uncocked to relax the springs. A silica gel packet in the bag helps prevent mold.

Where can I find repair services for the Canonet?

Look for vintage camera repair shops or online specialists. Many offer CLA (Clean, Lubricate, Adjust) services. For parts, check eBay or dedicated forums like Rangefinder Forum.

RANGE-VIEWFINDER

When the double-image of the Range-Viewfinder does not align, it should be adjusted in the following manner: Turn Screw C4221 when the deviation of the double-image is vertical.

Turn the Eccentric Screw of Lever C9285 to right or left when the deviation of the double-image is horizontal. Care must be taken not to turn C4221 and the Eccentric Screw of C9285 too far as the screw thread may become worn or its calking may become loosened.

Cover Plate C9252 need not be removed when adjusting the double-image.

See Repair Manual p.3.

When the Finder Mask does not move smoothly even after turning the Focusing Ring, the following adjustments should be made.

1. Check to see if Spring C4216 has become weak. If so, bend C4216 to give it more strength, or replace it with a new one.

See Repair Manual p.3.

1. When the pressure of Holder C4179 is too strong, bend C4179 to weaken it.

See Repair Manual p.3.

1. When Viewfinder Mask C9430 is touching Cover Plate C9252, make the proper corrections by bending C9252.

See Repair Manual pp. I S3.

1. If Viewfinder Mask C9430 is touching Aperture Scale Index C9429 or EE-Signal C4359, bend either C9429 or C4359 so that there will be a gap of approximately 1 mm.

See Repair Manual pp.2&3.

When the Aperture Scale Indicator inside the Range-Viewfinder is out of order, the following adjustments should be made:

1. Make necessary adjustments by turning the Eccentric Screw of Lever C9427. If after adjustment the needle should again become unaligned, it means that the calking of the Eccentric Screw has become loose. In this case, replace C9427.

See Repair Manual p.2.

1. If the needle of Aperture Scale Index C9429 is bent and is touching Viewfinder Mask C9430, adjust by bending the needle.

1. If Lever C9427 and Lever for Mask C4137 are out of place, adjustments should be made by bending C9427 upwards.

See Repair Manual pp.2&8.

1. If Lever C9427 and Arm C9428 are out of place, the upward and downward play of both should be adjusted with a washer.

See Repair Manual pp.2&3.

1. If the movement of C9427 is impeded by Lever C9427 and Film Counter Advancing Lever C9431 pressing against it, C9431 should be bent and adjusted so that it will not touch.

See Repair Manual p. 2.

When the Red Mark does not appear normally, that is, when the Red Mark appears even though the Shutter has been set for automatic photography, or when the Red Mark does not appear at all after the lens cap has been put on and the Shutter Button pressed, it may be assumed that something is wrong with the Red Mark itself. In this case, the following adjustments should be made:

1. If the movement of Moving Guide C4153 is bad, replace Washer W 2132 x 2, which is under Retaining Washer YS 1131x2 holding C4153, with one of less thickness.

See Repair Manual p.8.

1. Adjust the length of EE-Signal C4359 after loosening Screw SI-140157 x 2 securing C4359.

See Repair Manual p.2.

When the shutter is not released even after the shutter button is pressed down for automatic photography with the shutter speed set at 1/125 or 1/250 in bright sunlight, it may be assumed that the exposure meter has developed some kind of trouble. In this case, the following checks and adjustments should be made.

1. Check to see whether the meter needle is in the position shown in the figure with the lens cap on. Then take the lens cap off and see if the needle moves when the lens is pointed towards the light.

See Repair Manual p.2.

1. If the needle does not move, the connection between the photoelectric cell and the cord should be checked in the following order:

1) Window C4258 and Lattice Window Frame C9338 are removed by disconnecting Collar C4261 with Tool T06A-C4261.

2) Check whether the cord is firmly connected to Photoelectric Cell ES4003. Make sure that no naked wire is touching the inner side of ES4003.

3) Before tightening C4261, press down on ES4003 with the hand and check to see if the needle moves when light is focused on it.

1. If the above conditions are found to be normal but still the needle does not move, Exposure Meter CU066 should be replaced.

FILM COUNTER

If for some reason the winding mechanism becomes faulty and the film counter does not move forward, adjustments should be made in the following manner:

1. Check the Spring for Film Counter CU067 and reattach if it has come loose.

See Repair Manual p.2.

1. If the movement of the Stop Claw for CU067 is small, the Stop Claw will not mesh with the Ratchet Gear Teeth and this will prevent the Film Counter from moving forward. In this case, the tip of the Stop Claw should be bent.

See Repair Manual p.2.

When the Back Cover is opened, the Film Counter will automatically return to "2". However, if for some reason the Film Counter fails to return when the Back Cover is opened, adjustments should be made in the following manner:

Check to see if the Resetting Lever of Film Counter CU067 is not touching the camera body. If it is found to be touching the camera body, adjust by bending the Resetting Lever.

See Repair Manual p.2.

WINDING MECHANISM

When the camera shows the conditions described below, it may be assumed that the Winding Mechanism has become defective, and so the following adjustments should be made:

When the shutter is not charged even after the Trigger Lever is wound, the following adjustments should be made: Loosen Screw B1190. Float Winding Device C9266-11 and set the Shutter with a pair of tweezers. Then adjust the amount of charge by turning the Eccentric Screw of C9266-11.

See Repair Manual p.5.

When the Trigger Lever does not move, the following checks and adjustments should be made:

1. Check to see whether the Screw for the Winding Device is loose.
2. Check to see whether Spring C4049 is out of place. If so, reattach.

See Repair Manual p.5.

1. If Cone C4090 is caught between Lever C9267 and Lever C4051-03, loosen Screw S1777 and adjust C4090 by turning it to the right.

See Repair Manual pp.2&5

1. If Lever C4051-03 does not disengage itself from Lever C4044 when the shutter button is pressed down because Cone C4090 does not go down enough, Screw S1777 should be loosened and adjustments made by turning C4090 to the left.

When the Trigger Lever runs idle or when it winds many times before the shutter button is pressed down, the following checks and adjustments should be made:

1. Check to see whether Spring C4042 is out of place. If so, reattach.

See Repair Manual p. 5

If the spindle of Lever C4044 is bent, replace Base Plate C9262-09.

See Repair Manual p. 5

1. If the gap between Lever C4044 and Winding Device C9266-11 has become too wide because Lever C4044 has become worn out, adjustments should be made by turning the Hexagonal Eccentric Nut for Base Plate C9262-09 with Spanner 2 for C4041. If this is insufficient, C4044 should be replaced.

See Repair Manual p. 5

When the Shutter Button cannot be pressed down, it should be adjusted in the following manner:

Check to see whether Spring C4049 attached to Lever C4051-03 is out of place and if so, reattach.

See Repair Manual p. 5

When the Shutter Button does not return to its original position after it has been pressed down, the following adjustments should be made:

Check to see whether Cone C4090 is caught between Lever C9267 and Lever C4051-03. If so, loosen Screw SI 777 and make adjustments by turning C4090 to the right.

See Repair Manual pp. 2 & 5.

When the film cannot be rewound or when the film catches, the following adjustments should be made:

Open the Back Cover and set the Rewind Clutch Lever to R. Then check to see whether it will turn both to the left and right by rotating the sprocket manually. If it does not turn, see whether Clutch Lever C4023 is bent, or whether Clutch Shaft C4056 is held down properly by C4023. Then adjust by bending C4023, or replace C4023.

See Repair Manual p. 5.

INCORRECT FOCUS

When the Back Focus becomes out of focus due to some kind of shock, the following adjustments should be made with the use of a 200mm T-Type Collimator:

First, loosen only three of the S3787x4 Screws holding Focusing Ring C4256, determine the proper position by turning C4256, and when the proper position is found, loosen the remaining one S3787 Screw.

Lastly, set the oo of C4256 to the camera's Range-Viewfinder Distance Scale and again tighten all four S3787x4 Screws.

See Repair Manual p. 6

When the double-image of the Range-Viewfinder does not align due to some kind of shock, adjustments should be made after referring to the paragraph on "When the Range-Viewfinder's Double-Image does not align?"

THE SPANNER-2 FOR C4041

Lens Projection Test Unit

2. PURPOSE

When the Canonet is overhauled, for example, by disjoining the front panel with objective from the body or by disassembling the front panel with objective lens, it is necessary to adjust and reassemble them, while testing, in the following method of test:

(a) Correct adjustment shall be made of the focal plane of the camera in the same method as adopted for the 200mm T Type Collimator. (b) Test and adjustment shall be conducted, through the use of the Lens Projection Test Unit, as to whether the lens is correctly fitted in the camera body.

This formula may be applied also to the checking of the customers' claims regarding the quality of the lens.

It is necessary, however, to prevent the participation in the test work by those customers who have little technical knowledge; otherwise it may cause an unnecessary conflict with them.

3. TO BE USED FOR

Canonet

4. COMPOSITION

(1) The Lens Projection Test Unit 1

The Lens Projection Test Unit refers to the equipment for use in the test of the Canon Lens and Canon Cine Lens, which has already been supplied, with the exception of its attachment; so the Test Unit is not supplied with the recently-introduced Lens Projection Test Attachment-2.

(2) The Lens Projection Test Attachment-2 1 (3) Screen 1

This projection test screen is not supplied with the Lens Projection Test Attachment-2. White mat art paper pasted up on a wall, a white wall as such, or a suitable cine screen may be used as the projection test screen.

Its standard size shall be about 75cm by about 110cm, but it is desirable for its surface to be even.

This is because it is difficult to discern any image on a screen the surface of which is rough.

5. OUTWARD APPEARANCE

Fig. J The method of the Lens Projection Test for Canonet

6. HOW TO USE

6.1. The Lens Projection Test Unit without attachment shall be placed on a desk the surface of which is even, a screen being set right ahead of the desk. In this case, the Test Unit shall be made to face just toward the screen with a space of about 1.5 m left. The screen shall be about 75cm x about 110cm in size.

6.2. The lens shall be opened to F1.9 with the shutter kept to Time exposure.

6.3. The Lens Projection Test Attachment -2 shall be fixed in the back of the camera body by opening its back cover so as to be stuck close to the rail. In this case, the center of the Test Attachment shall be trained right on the optical center of the lens. In handling the Lens Projection Attachment, you must keep your fingers off the plateglass, especially the test chart.

6.4. The Lens Projection Test Unit shall be switched on.

6.5. The camera body shall be maintained so that the distribution of light intensity through the camera in the test position can be equivalent. In this case, a suitable holder may be used.

6.6. The helicoid of the lens shall be adjusted so that the test chart's image on the screen can be discerned most clearly.

6.7. If the test chart is imaged equally on the screen both vertically and horizontally, then it may safely be said that the lens is fixed properly to the camera body.

It is necessary, however, to note that tolerance, however slight it may be, is considered in proportion to the ratio of photographing. Even if at first sight the lens is fitted in the camera body in the wrong way, sometimes it need not be taken seriously if the ratio of photographing is taken into consideration in examining the image on the screen.

HOW TO USE THE 200mm T TYPE COLLIMATOR

1. NAME OF THE TOOL

200mm T Type Collimator

1. PURPOSE

In repairing the Canonet, when the front panel with objective lens has been removed from the body or when front panel with objective lens has been further dismantled, a 200mm T Type Collimator must be used to adjust the helicoid so that the focal plane will be accurately maintained.

1. TO BE USED FOR

Canonet

1. COMPOSITION

(1) 200mm T Type Collimator (collimator, pole, stand)

(2) Mirror 1

1. OUTWARD APPEARANCE

Fig. 1: The Appearance of the 200mm T Type Collimator. Fig. 2: The Illustration of the optical construction of the 200mm T Type Collimator.

6. HOW TO USE

1. 6.1. Place the stand of the 200mm T Type Collimator on a flat table, set up the pole and attach the collimator to the pole. 6.2. Place the mirror on the bench of the stand. Next, turn the heliographical mirror and adjust so that the field of vision is brightest. It is most desirable to use natural light. 6.3. Turn the adjusting ring for the diopter and adjust so that the crossed line within the field of vision is clearest.

6.4. Turn the adjusting knob directly underneath the scale and find the position in which the test target picture can be seen at its clearest.

The test target picture should be clearest when the scale is at the "0" position, but adjustment is not very easy until one gets used to it. Practice is necessary.

6.5. After the camera has been assembled, place the mirror against the camera's film plane position and close the back cover. Have the reflecting surface of the mirror facing toward the lens side.

1. Open the lens aperture to F1.9, set the distance scale to infinity, set the shutter speed to T (time), and open the shutter.

6.7. Place the camera with the top cover toward you on the bench.

6.8. Turn the adjusting knob directly underneath the scale and find the position in which the test target picture can be seen at its clearest.

If this position is between 8 and 10 on the black letter side, you are guaranteed of correct focusing of your camera.

7. HOW TO ADJUST

7.1. If this position is not between 8 and 10 on the black letter side, take the following steps: 7.2. Adjust the scale of the 200mm T Type Collimator to 9 on the black letter side. 7.3. Loosen the lock screw S3787 of the camera's focusing ring C4256.

See Repair Manual p. 6.

7.4. Place the camera on the bench. While looking at the field of vision, place your fingers on the focusing knob and turn the helicoid slowly, either clockwise or counterclockwise.

Turn the helicoid until you find the position in which the test target picture is clearest.

7.5. Make the infinity mark ∞ of the focusing ring C4256 coincide with the distance scale index and then tighten the lock screw S 3787.

See Repair Manual p. 6.

1. Repeat the inspection outlined in 6.8.

1. HOW TO TREAT AND PRESERVE

7.1. Give neither vibration nor shock to the Lens Shutter Testers.

7.2. Be careful not to let intense direct rays fall on the photoelectric tube on the Tester B.

7.3. Usually, test with the aperture full open.

7.4. The LIGHT of the Tester B corresponds to the aperture of the camera approximately as follows.

LIGHT	Aperture
1	open-2.8
2	4-11
3	16

The quantity of the swing of the needle of the meter and the brightness of the light source are not related, but the Testers cannot work correctly if the brightness of the light source is too much or if it is insufficient.

7.5. If the needle of the meter does not swing or if it does not return after it swings to another end when you measure X or M contact, examine the brightness of the light source and the condition of the contact of that point. 7.6. The lamp used as the light source in the Tester B is the one of 24V, 20W (for cars). 7.7. As the output of the photoelectric tube changes as time goes on, select the suitable LIGHT of the Tester B, regardless of the correspondence stated in 4.4. when you measure.

6. HOW TO USE

1. 6.1. Place the Inspection Device for Canon Meter on a flat table where no direct rays of the sun fall intensely. 6.2. Make sure that switches for the light source and for the fan are both OFF and the voltage control handle is turned full to the left. 6.3. Connect the cord to the power supply. 6.4. When the switch for the fan is put to ON, the fan works and the signal lamp is lighted at the same time. 6.5. Put the switch for the light source to ON. 6.6. If you turn the voltage control handle slowly from this side to the opposite (right way round), the light source gradually becomes brighter. Making it properly bright, measure the accuracy of the Canon Meter according to the directions below.

6.7. Measure 1

Set the film speed at ASA 100, shutter speed 1/8, and the aperture ring to AUTO.

Turn the time ring to the letter T.

Place the meter window equally to the center of the Opal Glass of the Inspection Device.

Boost voltage to the value indicated on the Data Sheet, Term 1, by turning the handle.

(For Reference: The brightness in this case is approximately LV 8, using ASA 100 film.)

Press the shutter button.

Detach the camera from the Inspection Device, watch the diaphragm from the back of the camera opening the hinged back and examine how the aperture works, following the directions below:

Turn the aperture ring slowly and check the point where the diaphragm begins to work, consulting the calibrated scales on the aperture ring. The aperture should show the value between F4 and F8.

Be sure to return the aperture ring to AUTO after measuring.

6.8. Measure 2

Repeat the same measure with ASA 100 and 1/125, on the condition indicated on the Data Sheet, Term 2.

(For Reference: The brightness in this case is approximately LV 12, using ASA 100 film.)

The aperture should show the value between F4 and F8.

Be sure to return the aperture ring to AUTO after measuring.

1. HOW TO INSPECT

7.1. Keep in mind that the brightness of the projection lamp, the light source of the Inspection Device, changes while being used. For the surface of the lamp becomes black and the quantity of light which falls on the Opal Glass is changed. When the filament of the projection lamp is burnt out, you should check the brightness on the Opal Glass with the new projection lamp you are going to use.

7.2. Use Canon Meter R which is correctly adjusted as the examining tool.

7.3. How to Examine

1. Choose one of the Canon meters as the standard and check it as soon as the Inspection Device is delivered to you.

7.3.2. Check the chosen Canon Meter R on the conditions according to the attached Data Sheet and record the indicated value.

1. Examine from time to time the Inspection Device by the chosen Canon Meter R and revise the voltage indication of each Term on the Data Sheet.

7.3.4. When you exchange the projection lamp with a new one, check it with the Canon Meter R mentioned above.

7.3.5. Be sure that the voltage indicated on the Data Sheet should be correct especially as for the low voltage! (0-40V for 100V and 0-100V for 220V.)

7.4. The projection lamp used in the Inspection Device is that of JIS C 7511 Projection Lamp C 100V 500WS (Metallic Cap F27-22), which corresponds to ASA PH22.851953 Projection Lamp (Dimensions for T10 Bulb).

1. HOW TO TREAT AND PRESERVE

8.1. Give neither vibration nor shock to the Inspection Device.

8.2. After use, let the voltage fall off to 0 by turning the handle left way round, put the switch for light source to OFF and, after it gets cool, put the switch for the fan to OFF.

8.3. Avoid as possible lighting continuously for long time.

8.4. Do not let the light from the outside (e.g. the sun, room lamp and so on) influence the Device while using (Above all, do not open the top cover and never allow direct rays to fall on the Opal Glass).
