- Buy EN-EL4a battery and charger
- Buy strap
Shipped, waiting for delivery.
Also found dodgy diode. It seem to be working, 0.74V Vf, but it was definitely heating up before. Not sure if it's "normal".
Problem is in that chunk of mechanics, aperture/mirror control unit.
One of levers for exposure metering unit was bent, fixed it. Should be some other problem somewhere too, which prevents mechanics to interact correctly.

Left to do:
- Receive battery and test with battery power
- Autofocus need adjustment, with 50/1.4D it gets too close. Likely AF unit aligment or adjustment.
- Standard AF-ON button does not work (no reaction). AF-ON on portrait side works fine.
- Refurbish rubber pads
- Clean image sensor. :)
