Removing the Film Advance

To remove the cap, wind-off lever, and springs, use a pair of dividers to carefully pry up the cap. Remove the lever and cam by using the same method.

Wind levers need something to hold them in place while being undone. Rubber friction wrenches are best because they won’t damage the finish. You can also use your fingers, a piece of rubber sheet, or an eraser. Pliers could scratch the finish.

You can remove the top plate by lifting the wind-on lever. There is a spacing washer under the wind-on lever that prevents the lens from being pushed out when you remove the top plate.

Lifting the Lid

If you remove all the screws, the camera should come right off. If you are removing a different model, check to see if there is anything blocking the top plate. If there is, try to figure out how to get it out. If you are having trouble, search online for help. Someone else might have already done this before.

Some rangefinders may have soldered connections. Canonet 1.9 uses a pressure contact connection.

The Konica Auto S3 is a standard part that has been used by many different camera makers. It appears to be a standard part, but there are some differences in how it works. The vertical adjustment is set from the top.

The Konica with the top plate off. The plate at B tells the camera if a Flash is in the hot shoe, you will need to hold this part out of the way to adjust the vertical position of the lens. Other cameras using this viewfinder rangefinder unit may have better accessibility because they didn’t feature the same ‘Flashmatic’ system as the Auto S3.

The Canon rangefinder doesn’t use a moving mirror. Instead, it uses an optical unit attached to the lens’ focusing mechanism to get the coincident image. This technique reminds me of the rotating prisms found on Zeiss lenses. I think this is a very elegant design.

The Canon rangefinder is an accessory used to adjust focus when using a camera. The rangefinder uses a small optical unit that moves as the lens focuses. This allows you to see the distance to your subject. The Canon rangefinder also has a vertical adjustment screw located on the back of the mirror. When adjusting the focus, the vertical adjustment screw must be turned until the image appears sharp.

To adjust the vertical alignment, use the flat-head driver to turn the adjusting screw clockwise or counterclockwise until the images line up one above the other. Rotate until the images also align horizontally. Make sure you’re doing this correctly by testing your adjustments on both close and distant objects.

The Canonet 28 rangefinder has a vertical adjustment screw that moves the lens mount up or down. Turning the screw causes the lens mount to move up or down. This allows you to adjust the vertical position of the lens mount without affecting the horizontal position of the lens mount.

However, turning the adjusting screw may cause the lens mount to move both horizontally and vertically. You should make sure that the lens mount does not move when you turn the adjusting screw.

Our Little Error

The camera’s light meter is located right next to the lens mount. When you take pictures, the light meter measures the amount of light coming into the lens. This information is then used by your camera to determine how much light should be allowed into the picture. You can adjust this setting using the little gray plastic piece on the back of the camera.

The Canon 110ED is designed to be taken apart for adjustments. You need to remove the grey plug to access the adjusting screw.
