Make sure your screwdrivers are of good quality, fitting the screws well, and put a white handkerchief down on your work surface. The screws won't roll away and are easy to see. The VIOOH is actually very simple optically: there are two lens cells and a prism train. 1. Remove the four screws on the eyepiece end. Screwdriver blade width should be 0.100" or 2.5 mm. Remove the plate. Clean both surfaces of the eyepiece lens. 2. Now you can see the prism train. It's held in a metal bracket fastened to the body of the finder by two screws with wide heads and thin slots. Remove the screws and lift the prism assembly out. Clean the two end surfaces of the prism train. 3. The finder mask is now visible. Clean out the inside of the finder body if necessary. Set the finder to 35 mm, clean the lens behind the mask and the front element of the finder. 4. Put the prism assembly back into the finder body and replace the screws. It only goes in one way. 5. Replace the rear plate and its screws. 6. Have a beer, then go out and use the thing. Goodbye and hello, as always. - -- C. L. Basso, K.C.S., M.Sc.
