Generally speaking, I've become a fan of K&F's filters. They are, and this kit is no exception, competitively priced quality filters.But this "kit" is a bit disappointing and, in hindsight, I guess I would have preferred to just buy the 3 individual filters.On the plus side is the obvious: being able to swap among the three included filters is quick and easy. Attaching the filter adapter is simple, and selecting the filter (or choosing no filter) really does take just a second or two.But here are some negatives to think about before you choose this kit over individual filter purchase:- The UV filter does not attach as strongly as the other filters. It sloshes around a bit within the adapter ring, and I'm actually a bit worried that a slight bump could cause it to pop out. By contrast, the ND and CPL filters attach much more firmly. (In case it matters, I'm using the 77mm size.)- The filters are "stackable", allowing for some creative possibiliities, but not entirely so. For example, the CPL filter can be seated firmly inside the UV filter, but not the other way around. So, your one or two seconds of switching/stacking filters may be a little clumsier than needed. It would have been nice if this kit had uniformly designed filter rings, so that all of them worked the same way.- It would have made so much sense if the adapter ring were also threaded so that I could screw on other non-kit filters. That seems like a missed opportnity on K&F's part. In other words, if I want to take one of my traditional 77mm filters, it would be nice if it could simply screw it onto the adapter ring. But instead, I have to unscrew the adapter ring to make way for my old filters. Perhaps this is K&F's way of nudging me to consider buying more of their magnetic filters to add to my kit.So, in short: the individual filters, as far as filters go, are great. But this kit has plenty of room for improvement.
