[72mm] Perfect for fitting Kase filter to my 72mm lens.

[Yes] If you understand how this filter works and use it properly you will get excellent results. At first I was wary because of some of the negative reviews along with the price, however both points I have proved wrong. First you don't have to spend hundreds to get a good filter, second some people have no business writing reviews. Yes the dreaded X effect it is easy to achieve especially at wide focal range but it is also rather easy to eliminate, If you have the flexibility. Note all these filters have this limitation since they are basically just two polarizing filters. I found no distortions or color problems out of the ordinary and have easily gotten all the results we buy these types of filter for. With this 95mm size using step-down rings I can use this on three of my lenses. I have noted some have mentioned not being able to use lens hoods, not sure how hoods would be used conveniently with a rotating filter to begin with. And the only time I use a lens cap is when I am done for the day. The filter feels solid and well made and the ring moves nice and smooth with no loose play, the filter also comes with a really rugged hard shell case and a lifetime warranty. I have a number of filters some Bower, Hoya and B+W that were way pricey but the 95mm B+W Variable ND is just way over priced IMHO So in the end glad I went with this it has proven I don't need to overpay to get good results

[Yes] Adapters for every lens filter threads, so you're ready to go no matter which filter you choose. I have an adapter on each of my main lenses. No screwing and unscrewing to use the filters on different lenses.

[Yes] Fastest and easiest filter set I have used. Changing filters is easy and convenient as they use magnetic technology. No more fumbling threading filers on and off. Of course the quality of the glass is superb so Kase delivers on quality and ease of use.

[Optical Glass] Much better quality than what I was using. The pouch is handy, keeping the filters clean and safe.

[Yes] Great value for money was packaged good so there was no damage to filters.

[Optical Glass] Ease of use and good color rendition were the main reasons I purchased this system. It is excellent. I need to remove my protective filter on the 10mm and 16mm when stacking 3 Kase filters to prevent vignetting. Very happy with the investment. Now trying to sell my Lee system for a reasonable price.....

[Optical Glass] When I tried to use my magnetic filters on one of my lenses I realized they wouldn't fit (designed for 77mm). B&H had the adapter I needed at a great price and got it to me quickly. 100% satisfied.

[Yes] I have been looking for a better way to use CPL and ND filters to my lenses. I heard about this magnetic system from a professional photographer who had used them. I have a hard time threading on typical filters.
This has been a lifesaver for me.

[Yes] I now have a set for 112mm, 77mm and 82mm. True I could have used step rings but you buy these for ease of use and lens shades don't always fit with step rings and you buy these for ease of use. Filter quality is excellent, no observable color casts, nicely machined. Only complaint is this set needs an extra sleeve in the case as you have to fit 2 filters in one slot. They probably think you have the UV on the camera all the time and don't need a 6th slot in the case, but a 6th slot would have made this perfect.
