Replacing 50mm Cintar Lens

1. Remove either interchangeable lens as you did the Cintar Lens.

If your camera has an Idler Gear Cover that's smaller in diameter than the Idler Gear, such that you can see the Idler Gear teeth when the Idler Gear Cover is in place:

• Set Rangefinder Dial (A) at infinity.
• Grasp Cintar Lens at Collar (H).
• Screw Lens into the camera turning to the right past resistance point until seated firmly.
• Turn Lens (K) to the left until the first tooth you come to is positioned to engage Idler Gear (B).
• Drop in Idler Gear (B).

If your camera has an Idler Gear Cover that's larger in diameter than the Idler Gear, such that you can NOT see the Idler Gear teeth when the Idler Gear Cover is in place:

• Set Rangefinder Dial (A) at 3 feet.
• Grasp Cintar Lens at Collar (H).
• Screw Lens into the camera turning to the right past resistance point until seated firmly.
• Turn Lens (K) to the left until the last tooth you come to is positioned to engage Idler Gear (B).

2. Screw on Idler Gear Cap or Idler Gear/Idler Gear Cap assembly(C).

• Turn Rangefinder Dial (A) through its focuing range and then back towards infinity until it stops moving.
• Make sure Ranqefinder Dial stops exactly at infinity mark. This is essential for proper focusing.
• If it does not stop right at infinity: Note how many teeth it's off by. Remove the Idler Gear as you did in step 1. Adjust the lens position by the number of teeth noted before and replace Idler Gear and Idler Gear Cap.

Camera is now ready for picture taking. Keep supplementary lenses in leather case for protection when not in use.
