amci Posted July 14, 2018 Share Posted July 14, 2018 Everything seems to be fine and the meter is behaving as expected; however, when tested against my other cameras, and my friend's sony a7, it is underexposing by a couple of stops. I'm wondering if anyone has a source for a guide or a schematic so I can adjust the meter a little. I also read somewhere to try cleaning under the dials (with the top cover off); I'll try this, but before I open it I'd like to see if I can find a good schematic. Also if anyone knows of any forums where there is discussion of camera repair that would be great, thanks! Link to comment Share on other sites More sharing options...
AJG Posted July 15, 2018 Share Posted July 15, 2018 Before you try taking this apart, check one thing: Is the exposure compensation dial set to two stops under? That could explain what you're seeing. If that isn't set to 2 stops under, you could try setting the ASA to 2 stops slower i.e. setting ASA 100 for ASA/ISO 400 film. This should get your meter to give you proper exposure.

BeBu Lamar Posted July 16, 2018 Share Posted July 16, 2018 If I were the OP I would test the camera out with film and see if it's actually underexpose. A lot of time the meter and the shutter speed are off by the same amount and fixing only the meter would result in bad exposure. Link to comment Share on other sites More sharing options...
