Sony OEM RX1 hood.. just came in..
I use a Canon with a 50mm Zeiss makro lens with shade. It's great to store the camera without a cap. Love it. The Camera was tethered to a laptop while downloading. I picked up the laptop to bring it to bed and the camera dropped off the table. Hood is now bent put still works fine. Does not stow when reversed anymore though because it's bent out of shape a bit. Lens was NOT damaged at all. It costs $70 to replace for an unbent one. I guess, for the RX1 I'll just have to use my hat or hand for now.
