dpattinson Posted August 20, 2009 Share #1 Posted August 20, 2009 Advertisement (gone after registration) This week the manual shutter speed wheel on my M8 has begun to malfunction again. (Was supposed to be fixed last time I sent my camera to Solms, but I suspect it was not reproducible at that time). What happens is that I lose all speeds faster than 1/360; manual speeds set normally up to 1/360, then at a setting of 1/500 the camera fires at 1/360. For speeds faster than 1/500 it progressively sets slower speeds (1/250,..) until at a setting of 1/8000 the shutter actually fires at 1s. I guess this might be dust or something interfering with the contacts of the wheel. I can sometimes 'fix' it temporarily by spinning the wheel fast for a few turns, however it can revert to 'wrong' speeds between shots. Has anyone else experienced this problem? Any insight into what might be causing it? David. Link to post Share on other sites More sharing options...

Shootist Posted August 20, 2009 Share #2 Posted August 20, 2009 I haven't notice this on either of the M8's I've had. I mainly use my chrome M8 and use manual shutter speeds some times and they always seem to fire OK. But then about the only time I use manual is when I'm in low light or when using a flash and the speeds are usually always below 1/500s. Link to post Share on other sites More sharing options...
dpattinson Posted August 29, 2009 Author Share #3 Posted August 29, 2009 Seem to have fixed it again by rapidly spinning the dial a few times. Odd that both of the wheels on my camera are flaky. Link to post Share on other sites More sharing options...
marknorton Posted August 29, 2009 Share #4 Posted August 29, 2009 The shutter dial works by connecting 1 or more of 5 concentric tracks to ground. The "A" position, for example grounds none of the tracks with the wiper at "3 o'clock" in this picture. The possibilities are that the tracks are dirty or greasy, the contacts are not pressing reliably against them or that the ground connection, off from the pad at 3 o'clock to a screw to the right of this picture. This can really only be solved by taking the top off the camera to take a look and have a bit of a clean. Not sure that spinning the wheel quickly is the best way to solve the problem long term.

Doc Henry Posted August 29, 2009 Share #5 Posted August 29, 2009 Mark, In summary, it is therefore a problem of tightening : the button is not properly gripped and there is no contact in that case isn't? Link to post Share on other sites More sharing options...

No, most likely, the tracks and the contact fingers need cleaning. Link to post Share on other sites More sharing options...

dpattinson Posted August 30, 2009 Author Share #9 Posted August 30, 2009 I guess it would be nice, if parts like the shutterspeed dial are not going to be sealed, to be able to clean them in the field without having to disassemble the camera.
