This CPL filter performed really well when used on my most recent vehicle rig. I was most concerned with the reflections that the windshield would produce at any given moment throughout the shoot. Thanks to this filter, I was able to drastically reduce the glare and focus on my subject who sat inside the car. The filter itself is quite practical to use. Although it is a bit tough to remove when using step-up/step-down rings if you tighten it too much, it's generally a good rule of thumb to not overtighten any filters. In this instance, I just wanted to make sure everything was incredibly secured as the rig would be in motion, but otherwise for normal scenarios I wouldn't have had that issue at all. Overall, I do think it's well worth the cost. I've used cheaper alternatives that haven't really offered the same result as this CPL filter by K&F Concept. Personally, I believe that sometimes using cheap gear ultimately cheapens the results and overall quality of some videos. In this instance, K&F Concept did an exceptional job given the price. Yes it's definitely premium, but it's well worth the cost.
