Basics of Function
While the body of the 110s and the later models may be almost identical, the fact that the 110s use medium format lenses and shutters makes their operation a bit different. Unlike the description here, I am not going to go into details about the finder or the rollfilm back as they are obsolete in this conversion.

The first step to learning about this camera is to open the front. Push the metal tab on front and the camera will pop out slightly allowing it to be fully opened. It will click and lock when fully opened. Its now rock solid for using the tripod slot on the font by the focus knob.
The lens and bellows can now be pulled out and locked to the focusing rail. Notice the small black tab under the lens, pinch it to unlock and pull it forward.
To close the camera, push down on the strut arms while closing the front.

When extending the bellows, check for any holes, tears or brittleness. Luckily mine is nice and supple, so I luckily won't need to replace them.
You can see the little metal tab next to the focus knob that unfolds to hold the front of the camera up straight while in this position. Nice touch Polaroid.
With the camera now fully open we can look at the heart and soul of the 110A, the lens and shutter.
