Freewell 67mm Threaded Hard Stop Variable ND Filter Standard Day 2 to 5 Stop

I ordered the 2-pack lens set and I’m really happy with the quality. They work great in bright daylight without changing the image too much. I always use them when filming outdoors in sunny weather. Definitely a must-have for content creators!

Game-changer for controlling exposure in bright conditions. The hard stops prevent over-rotation, and the build quality is top-tier. Perfect for my Sony a7C II setup when filming travel or product content outdoors. Zero color shift.

It works very well, it does not generate vignette, maybe a small color change

I don’t have any others to compare these to yet however the magnetic lens covers that come with these seem very good and have good retention for only being magnets. I noticed very mild halo affect but only after Prost edit. They adjust evenly and smoothly and I am looking forward to what I can achieve with these in my bag.

Even though its over $200 for the set, the value you get in terms of build quality, optical quality, size, features, and performance is far greater than similar VNDs from other bigger companies. Build & optical quality is right up there with the best of them. The knurling on the ring makes gripping for adjustments & installation/removal very easy. Have not had any issues screwing it onto my lenses or step-up rings. Much thinner than the Hoya I had been using. The hard stops at the ends & numbering on rings take the guesswork out of wondering where you are on the filter and eliminated the dreaded 'X' cross-polarization on so many VNDs. The metal magnetic lens caps (wow!) protects the filter when not in use. Its strong enough to not fall off if bumped a little, but easy enough to pull off when you need it. Very minimal colorcast which make editing so much easier. So when you factor everything you get compared to other VNDs, some costing more (for just 1!) with worse performance, the Freewells are a bargain.

This filter had a good range of ND strength, and I loved that it had hard stops as well. One quirk about it is that the tension when rotating the front of the filter was fairly strong, so when adjusting it, it is possible to actually unscrew it from the lens, because the tension in the filter can be stronger than the tension holding it onto the threads, unless you really crank it onto the lens, which I never wanted to do.However, in spite of not cranking it down, and making sure not to cross-thread the filter, on a wedding shoot this past weekend, the filter wouldn't stay on the lens. After closer inspection, I saw that the threads on the ND filter had stripped away, causing it to no longer hold onto the threads of the lens. I was super disappointed, as I really otherwise loved this filter. No noticeable color cast, good range, seemingly good build quality, and good price. Can't have everything, I guess, and it's too late to send it back.

I had a very low quality variable ND filter previously that would introduce reflections on my video and pictures. That filter left such a sour spot in my photo arsenal, and I was reluctant to buy another variable ND. However, I needed a solution for recording videos in various lighting and I found out that the same company that makes ND filters for my drones started making round filters for my mirror-less camera setup. I figured I would give them a shot and was pleasantly surprised that I did not have any internal reflections anymore--but it also works as a great low-color-cast ND filters for long exposure photos.I have to add that the labels are very clearly visible and have a very pronounced end at the extremes, making it very easy to operate without looking at the filter. Also--I tend to leave lens caps in the box since they seem to pop off when I least expect and I lose them. This one attaches very nicely (magnets!) and stays on securely.

Along with looking slick, its slim form factor means my 24mm G Master doesn’t have Vignetting. No cross polarization because of hard stop, unlike other variable Nd filters in this price bracket (tiffen).Warm color cast is easily solvable by setting custom white balance.One thing to note, if you plan on shooting videos during the day with a lens that has a fast aperture, pick the 6-9 stops instead. Or maybe just buy both.Edit for update: I recently had a problem with my filters, and it made my heart sink to my stomach because I spent hard earned money on this filter. So I emailed them to see what they could do for me. They replied to my emails swiftly and were able to settle my dispute quickly. I can't recommend a commend their company enough, they stand by their warranty without a fuss.
