I should also ask if anybody has some filter recommendations for these lenses?

I am accustomed to having a UV, CPL, and Graduated ND Filters with my other lenses. Any recommendations or examples would be greatly appreciated.

There's no need for UV filters as such on digital cameras. Opinion is divided as to whether you should use them to protect the lens: these days I rarely do unless I'm going somewhere that damage is a real possiblity, because the newest lenses have pretty tough protective coating on the front element.

You can use CPL on UWA but it's hard to avoid getting the sky a lot darker on one side compared to the other. DA15 users reckon that it brings out blue skies very well (as does the Sigma 8-16 - it seems to happen more with some lenses than others). The DA15 uses 49mm filters like most of the other DA primes so a CPL is cheap if you want it for reducing reflections rather than just intensifying blues.
