This thing is excellent - I can't detect any issues with it at all. It's clearly marked for ND2 - ND32 so you can even set up your shots with math instead of looking at the viewfinder!

I was skeptical to buy any filters since I have very expensive glass but this is very impressive!! For the nerds out there, at sunset I can shoot at 1/160 and get the colorful clouds no problem

A few other reviews suggested this was not an ND32 filter. I too did not think it was. I put it to the test and can confirm this does reduce light by 5 stops. I will say though that the “min” mark on the filter is not 2 stops it’s more like 1. But to be fair most variable filters will say the marks are a guide and not an absolute. There is some warming color cast but that is not unique tho this filter especially at this price point. If you are printing large prints there may be some image quality degradation, but it would not be noticeable in most situations.

First K&F filter and actually surprised a bit by it's quality for such a affordable price

Product: 58mm Variable ND2-ND32Description: 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 400ND32: F4.0 1s ISO 400The 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/1.8Camera/Settings: Shot on a Canon Rebel SL3, with custom white balance settings set to +/-0,+/-0 for raw color quality.

I bought this 72mm ND2-ND32 Variable Neutral Density ND Filter Nano Coated on Amzon.com on 4/17/2019 (Ordered on April 17, 2019 Order# 114-1879673-7654625 ). $56.99.
two days delivered. Looks great. I like it.

I like this filter and it performs well although I'm not sure if it's the filter or what but at some strengths there is a vignette in one of the corners.

The filter works as described and has a quality feel beyond what is expected in this price range.

Photography is a hobby for me and this filter worked very well for the cost. I was most pleased with the results I achieved with this product.

I have used this filter on my Fuji X-T3 with my 18-55mm f2.8-4. Shot outdoors/sunny, overcast, at noon, at 6pm summer time still lots of sun (back lit). and it is the best for your buck.i researched at least other 3 products before buying this one.the thing is a beast, super sturdy, the ring flows nicely as you adjust your exposure, none of that dry spin like other "affordable" filters, feels expensive and you can shoot in totally sunny situations with low aperture and low shutter speed with no problemo!!!
