I've had a lot of filters and prefer the ones nowadays with the very high transmission coatings designed for digital sensors and their high reflectivity. I bought a new X100, and a used "kit" of the Fujifilm adapter ring/hood, and a Fujinon 49mm Super EBC filter from KEH.com. The filter has a very low reflectivity on par with some of the best top "digital filters" I've had from Hoya, Kenko, and Marumi. I don't even know what they cost new, but it seems to be an excellent filter, which is what I expected. I got quite a deal on the package used from KEH and I think the filter is worth having.
