Sony Nex-5N LCD protector

Excellent question. I had purchased the Sony PCK-LM1AM semi hard screen protector for what I thought was going to be a C3. When I switched my order to the 5N I assumed the protector would not work with the touch screen but happily it does. And the Sony cover has a cutout for the screen brightness sensor as well.

I'm guessing any of the hard protectors will work though...
