Description: The rim of the filter is made out of what I'd assume is aluminum, coated matte black, (which has a nice weight to it, and has hard stops at ND2 & ND32). The rim itself is actually fairly nice. It's easy to put on, and easy to take off due to the wide ridged design around the base of the filter. The high index optical glass is indeed nano coated to protect against water/oils from fingerprints, rain, & etc. Which are easily removed without struggle in my testing with a clean micro fiber cloth (not included). The glass itself has a slight yellow tint to it (which you can see from the photo comparison), which can also easily be corrected through your cameras auto white balance, or lightroom. The filter also doesn't loose to much detail if adjusted properly which is nice as you will see from the photos, and their description in the next section.

Photos: The first four photos of the product were taken without any filters. Though the next two of the black & red mouse pad were to show detail comparisons. These two photos were taken about 1-2ft away, but are cropped to show detail. Which were slighty adjusted to be as equal as possible.
Without the filter: F4.0 1/15s. ISO 400
ND32: F4.0 1s ISO 400

The next 6 photos of the flowers next to the bird bath were taken without adjusting any settings to show the darkness of the filter (F5.6 1/320s ISO 100), in this order: No Filter, ND2 1st, 2nd, 3rd, 4th, & ND32 5th stop.

Overall: The produce works well, and is well made! I would highly recommend picking one of these up, along with a circular polarizer. Though only notable things I found with the product is that it has a slight yellow tint of the filter, the front thread size of the filter in bigger then 58mm, and the top of the filter very slightly wiggles. Otherwise it gets a solid A from me!

Extra: I used a 49mm-58mm step up ring for the filter to fit my Canon 50mm F/1.8

Camera/Settings: Shot on a Canon Rebel SL3, with custom white balance settings set to +/-0,+/-0 for raw color quality.

This is a great option for outdoor shooting whether it be photo or video. You can easily just twist the filter to change the amount of light going into the lens and it's much easier than having to keep changing out different strength filters or using a 4x4" filter piece like a Cokin filter. There is no vignetting or "X" pattern that can show up in other models. This is very easy to use, even for the beginner and is a great thing to have when you want to travel lighter and plan on shooting outside.

Fast delivery. Packaging of the glass in a high quality case. Unfortunately, I haven't been able to test filters yet, but I've already bought several. Was very happy with all of the filters. Price performance top.

This is a good quality variable ND filter. While the marketing says that there is no "X", this is not true with wide-angle lenses (due to physics and such), as I noticed an "X" on (or near) the lowest and highest most settings. Other than those extremes, the filter works great on my wide-angle lens. On a typical non-wide-angle lens you do not have the "X" showing up.

I especially appreciate that they had a 55mm size, as it is an odd size. My Canon mirrorless 11mm - 22 mm lens has the 55mm thread, so this filter is perfect for my needs. I can also use this on my 49mm threaded lens with step-up rings.

The magnetic lens system is the absolute best for me, the lens quality is good. I am very satisfied.

Typically you get what you pay for when it comes to camera gear but this product is one of those rare exceptions. I was very hesitant to purchase it based on the price but after watching dozens of reviews on variable ND filters I figured I would give it a shot. I have never been a fan of variable ND due to some of the image artifacts they are known for. I always used individual ND filters as needed which can be a pain when shooting run&gun video.

I loved that this ND filter had hard stops to not go past the usable points of filtering and that they somehow eliminated the dreaded x shape in the picture. While photos may be able to recover from some of these artifacts it is much harder to get around them in video.

So far I am completely blown away at how good this VND filter has performed. The picture quality as far as my initial testing has shown is stellar. Color cast seems to be at a minimum and there is absolutely no X shape or vignetting. To be fair I bought the 82mm size version and use step up rings on my GH4 and m43 lenses but so far even on the 62mm wide 14-140 lens visually the VND seems perfect.

My only super tiny issue which is true of all VND filters is that turning a filter on the front of the lens while shooting video is very easy to accidentally get my fingers in the shot. Would be nice to have the option to screw in a tiny handle into the VND so I have something to grab onto and not get my fingers in the shot. Maybe something the manufacturer can consider for a future product.

I love this filter great for Photo & video.
But at 10mm on my 80D Crop sensor it casts a shadow above.
if I zoom in a bit like 14mm it goes away.
NO X, No Color cast. Great Filter... As Advertised. and Great Build...

The magnetic works great, So far I used it only once and it’s okay

The filter is awesome
