PLEASE READ:
This camera body and lenses are being sold as-is.

I have tried to get the battery compartment to open just by hand. It won’t budge without some sort of tool or lubricant, which I have decided not to use as I do not want to cause any further issues with the device.

After fidgeting with it and tapping on the battery, the camera powered on briefly and the buttons were responsive. I have not tested with film.
