Freewell Magnetic Quick Swap System 82mm Glow Mist 1/4 Camera Filter - Professional Photography & Videography Lens Accessory for Cinematic Effects

This filter system addresses one of the most aggravating aspects of using filters, screwing them on and off. Having the magnetic connection allows you to transition quickly from filtered to non filtered videos and photos, which is very useful for saving time when you are moving from outdoors to indoors. If you are shooting for an event like a wedding, those moments can be precious, so it helps that you don't have to waste time screwing off your ND filter. I opted for the ND 64/PL filter which fits my largest lens, the Sigma 16mm/F1.4. I initially thought that the UV filter attached to the screw-on ring would be an issue, but I have seen no degradation while shooting with the UV filter on, so I don't plan on taking it off. I read that Freewell is supposed to be releasing a standalone ring later with no glass. Until that happens, shooting with the UV filter on works for me.Also, the magnetic lens cap is a plus. You can even stack the cap on with the ND filter attached. While, this works to secure the cap in place without it falling off, I will say that attaching the magnetic lens cap directly to the UV ring creates a stronger magnetic bond. The magnetic jewel case is also very durable and should be great for protecting my filter when it is stored away in my camera bag.Overall, I am very impressed with this filter. It is so satisfying how the filter snaps into place. I'm looking forward to Freewell releasing magnetic step up rings. This filter will definitely be a staple in my everyday camera accessories and I would recommend this to any amateur or professional photographer/videographer.
