I first ran across Freewell magnetic filters on Adorama’s website. I did not see many reviews on their items and when I went to their website, it appeared they concentrate more on drone filters and accessories. I don’t know if they just started out making filters for DSLR cameras, but their options of products is limited. The only filter I see offered on their website is a Hard Stop Variable ND filter, so back over to Adorama. I searched “Freewell” and limited my search to “photography” and it came back with 56 results.
The Freewell filter I have is 99.99 at Adorama, came with a magnetic adapter ring, a magnetic lens cap, and a lens cloth which seems to be standard with every camera accessory purchase you make. I think I have accumulated 82 lens cloths, but never seem to have any on me when I need them.
My biggest pet peeve when using screw on filters was when you attempt to do long exposure. Acquiring focus, screw on filter, take picture, take off filter, recompose, put filter back on etc. I’ve dropped, smudged, and had the screw on filters get stuck more times than I can count.
Here is the exact item: Freewell Magnetic Quick Swap System 77mm Neutral Density ND1000 (10 f-stops) Camera Lens Filter, includes UV Filter for 99.99.

Set up was fairly simple right out of the box. Just had to screw on the magnetic adapter ring and viola!
I have taken it out and used it about 3 times so far. Due to it being Ohio in the winter, I haven’t had the opportunity to try it out with bright sunlight, but did go out during the day between noon and 3:00PM. It was cloudy and slightly overcast, but enough sun that my base exposure exposure hovered around 1/100 with an aperture of f4 and ISO set to 64.
The first time I took it out I noticed alot of vignetting wide open at 24mm. It disappeared when I zoomed in a bit, but I did purchase a wide angle lens and would Iike to be able to use it to it’s full capacity. The photo below was taken at 2: 37PM. Fair amount of clouds, but the sun did peek in and out on occasion, and I was able to get a 61 second exposure, f/16, ISO 50. This is a 24mm so you can notice the filter around the edges. This is SOOC.
This photo was taken the same day at 1:40PM. This is also SOOC and I was able to take a 41 second exposure, f/16, ISO 100, at 120mm.
This last one was at 10:19am. Still overcast but a bit brighter skies. SOOC, 1 second exposure, f/4, ISO 400 at 112mm.
With the exception of its limitations at 24mm, the widest my lens goes, I would say I love the filter so far. I did not notice any color cast to the shots as I have had with other filters. It was extremely easy to take on and off and seemed secure, although I did not chance leaving it on while walking around. They advertise that it is Optical Glass, waterproof, dust proof, oil proof and scratch proof. I was shooting in sandy conditions and had many splashes from Lake Erie and did not have to clean the lens when I was finished, other than the smudges from my fingers when I wasn’t really careful.
* Can‘t use lens hood, vignetting when shooting wide open with a wide angle lens
No color cast, easy to put on, cost
I would say the only thing I need now is to get the polarizing filter to go with it. From what I understand, you are able to stack the filters. I’ll let you know how that goes! Happy Shooting!
