Introduction |
A common failure of the Pentax ZX-5n is the Mirror Drive Lever. This is a plastic lever on the side of the mirror box that moves the mirror up and down during an exposure. The plastic tip that follows the rotating cam can break off leaving the mirror stuck in the up position. The shutter should still fire normally but the mirror won't travel its full stroke. Additionally, with the mirror stuck, the viewfinder will appear black and the camera will not be able to autofocus. | | This guide explains how to disassemble the camera to access the Mirror Drive Lever as well as how to install the new part to ensure proper functionality. A general understanding of how cameras work is recommended. Some technical soldering is also required. |
