All 3 filters for me are very useful. The stand-alone ring however, I'm wasn't sure how much I'll actually use it but surprisingly I just leave it on my lens unless it's pretty bad weather, which in turn I use the UV filter as a protective layer for the glass. Personally, I haven't found the UV filter to do much other than to protect my lens and because the glass of my lens is such high quality I don't leave it on as it could degrade the photos, that's why I use the stand-alone ring. I haven't noticed any degrading when using the UV filter so no complaints. As mentioned earlier, however, I only use it to protect my lens. The CPL filter works wonders and the ND filter is great for long exposer shots. the combination with the magnetic touch make this absolutely flawless. would recommend.
