I use a few standard filters with this camera. They all (B&W and Hoya) work fine. No need to buy an expensive slim filter, that is a waste of money. To each his own but I did not even use a UV filter with this camera while trekking in Ladakh, India at altitudes up to 5,600 meters. I did not needed it (using Fuji 160s and Reala). Some of those picture can be seen at:
Enjoy the camera, it is great!
