Petri 1.9 color corrected shutter problem

[Fabien3d]

Hello,

I’ve just had a Petri 1.9 color corrected camera and I’ve got two issues:
- I have to press the release button real deep ; if I don’t, I can’t cock the shutter anymore;
- if set at speeds from 30 to 1, the shutter remains open, I must cock once again - if I have deeply enough pressed the release button - to close the shutter; from 60 to 500, no shutter problem.

Any suggestions?

Thanks!
