So you want to make the switch from Nikon or Canon to Fuji? If you were using variable neutral density filters or polarisers with your Nikon or Canon, it might be good to know that these will not work with Fuji camera even though they fit on your Fuji lenses. Why? Because the way the Fuji sensor is made (X-trans) interferes with the rotation system of the filters. This results in the creation of very strong white patches or blotches in the image. Give it a try and you'll see in your viewfinder.
You can however still keep all your other filters as long as they are not variable, meaning that they don’t rotate.
