I got a broken Hi-matic 9 from a friend for free. I already have experience from cleaning the shutter on Canonet, and this was obviouly the same problem - the shutter leaves were sticky. I decided to clean it properly, so I separated lens from the body, removed all glass from lens and flushed the leaves with naphta and then brushed with cotton sticks. Here is a picture taken just 5 minutes ago: The shutter seems to work now, from 1s to 1/500s. However there are some problems: - B works more like a 1/4s and it doesn't stay open - aperture diaphragm doesn't move at all when I move the aperture ring I don't care much about the B, but the aperture bothers me. Any advice would be much appreciated. Thanks in advance, Ondrej |

I usually take things apart before cleaning, wetness or dirt between blades can stop them from moving at all, the removal of all glass is just the initial step. My experience with the Mi Hi-M 9 shutter (the same as on the Oly 35SP: Seiko FLA, IIRC) is that it has to be really clean, so "flushing" it, AKA emptying a bottle of naphta in the shutter, is perhaps the wrong method. Dirt will not be completely removed and as soon as the shutter gets dry it will become stuck again if there is any residue on its components. In severe cases cleaning means to separate the shutter from the body or erven taking it apart, W. |
