Yes, it's compatible.
I have been gobbling up these cards from my local Costco for a vacation trip this summer and they work very well in the 5n both for still and video.
I have bought a new Sony nex 5n camera, i will receive it in 2 weeks.
I bought a 16gb memory card too, this one:
But amazon send me a uhs-1 16 gb card (45mb/s). I now this one is faster, but i dont know if its compatible with the camera as it is uhs.
Does anyone know this? Will i have any problem with the memory card?
