I am using this on my XT3 16-80 f4 and it's perfect match for me when I need to record in HLG during bright daylight. It has almost no impact on sharpness (you would need to pixel-peep to absolute details and even then the difference is minuscule, makes no visible difference in 4k video though) and no visible color shift.

I bought these Freewell range of filters as they were one of the first to use a magnet rather then a thread to attach the filter to the lens, and this makes life so much easier when swapping filters

Easy to swap quality filters. Only downside is the lens cap will take the filter off when you remove it (if you put the cap over a filter on your lens), but other than that, I love the ability to throw filters on and off quickly. I can also use my older screw-on filters on top of these, so I can stack a magnetic CPL, magnetic ND16 and a screw-on ND1000 for a long exposure shot (as an example).
They are very good quality with no more color shift than any other filter on the market.
Also as a tip, I bought the largest filter I needed and bought the freewill step up rings for my other lenses. This way I only needed to buy one set of filters. The step up rings from Freewell have the magnetic base built in.
One last thing, the filters now come with 2 base rings, one with a UV filter and one that is just the open ring (no glass).
When I received the ND filter I could not get it to work right with the open base ring that I attached to my lens. Then I noticed the UV base ring was already attached to the ND filter in the package (they are so thin I could not tell), so I was trying to attach one base ring on top of another, so I just separated the UV base ring and put it away and viola the ND filter fit perfectly into the open base ring. I do not like putting extra glass on my lens, so I dont use UV filters.
