Originally posted by guitarsammy I was recently given a Pentax SP500 with Takumar 55 2.0 lens.
It all looks in pretty nice shape, so I loaded it up with some cheap film to give it a test run but have run across a couple of issues:
1. When using the meter (engaging it by pushing up the switch at the front of the body), every few shots the mirror will remain stuck up. This is resolved by disengaging the meter by pushing the switch back down, and then firing the shutter.
2. The exposure counter remains at "less than zero" (i.e. to the right of zero, where it would be if no film were in the camera) even when I have wound the new roll of film on and throughout the entire roll of 24 shots, it didn't move at all.
Reading online, I suspect issue 1 might be rectified by lubricating a couple of parts. Does anyone have any advice on which parts I would need to lubricate, ideally pointing me to any diagram/photo of the parts?
And does anyone have any advice on issue 2?
Ideally I don't want to spend any money on this (free) camera, so I would like to go about carrying out a service myself.
Also, I am in the UK. Does anyone know where I could buy some quality new light seals/mirror damper in the UK or Europe?
Thanks.
It sounds as if the mirror is sticking to the foam cushion at the top of its motion. When the mirror flips up, it is stopped by a foam cushion around the focusing screen. With age, the material deteriorates and get sticky. The solution is to replace the foam. There are kits available on the internet to do this.
Have you developed the film? Are there images on the film? If not, its possible that you never really got the film leader started properly on the take-up spool. With non-motorized film cameras, such as the SP500, the easy way to tell is if the rewind knob turns as you advance the film. After you load the film, rewind the film just a little bit to put tension on the film. Then, as you advance the film, watch the knob. It should turn. If not, the film is not really advancing.
The other possibility is that the rewind button on the bottom of the camera is stuck. This is the button you push to release the internal advance mechanism and allow the film to be rewound into the canister. When you load the film, this button should pop back up within a half turn of the advance lever.
If there is something more seriously wrong, you can always send it to Eric Hendrickson for a CLA.
