SPECIAL NOTE: 636 AF AUTOFOCUS CAMERA:

Model 636 AF Autofocus Camera, from a service standpoint, is similar to the 636 OneStep/Close Up only in outward appearance.

As an extension of the 636 Camera line, the 636 AF uses a slightly modified version of the Impulse shutter and a repackaged version of the Joshua electronics and software. It uses wink autofocus from two feet to infinity, a rapid recharge strobe with a range of 10 feet, and has a maximum shutter aperture of f/12.

In addition to more than two dozen unique parts, the 636 AF camera uses a combination of parts from the 636, the Impulse Shutter and Joshua electronics.

4. As the solenoid pulls in, it releases the walking beam from the shutter latch. The spring-loaded S5 actuator drops down, closing the S5P and S5L contacts. S5L starts an internal clock. The camera electronics signal the solenoid to deenergize.
