OK, I managed to get into the darn thing (not without breaking a bit of plastic).
This camera was definitely not meant to be easily repaired!
More wires under the hood than in my hi-fi system.
Now, I have to remove the bayonet to remove the front housing to get access to something.
I tried removing the front plate as one unit but it seems it doesn't work like that...
I just hope I remember where every friggin screw I had to remove actually goes...
