72mm Fader ND2-32 (1-5 Stop) Variable ND Lens Filter Neutral Density Filter for Camera Lens NO X Spot Nanotec Ultra-Slim Weather-Sealed

Went on perfectly and quality feels great. Used it on a sunny day and was very impressed.

If I pay hard earned money for a product I expect to get what I pay for. Often I am disappointed. KnF products are a surprising UNdisappointment. This premium lens filter comes in a lovely box and wrapped with care in a case that will protect the filter from all the bumps and falls and stuff that comes along with carrying equipment out into the wilds of life. I've had Tiffen, Cokin and a bunch of generic brands I've sourced from yard sales, eBay camera shops and been gifted but these are by the best I've used. Looking forward to years of use.

I bought a different version (MFT ) before, and because I really loved the nd filter, I decided to buy another one for my full frame camera. Really good quality.

I'm a professional photographer and for my fast-paced outdoor portrait sessions with the flash unit, I was looking for an ND filter to keep the shutter speed below 1/250sec.at an aperture value of f/2.8. I had always used fixed ND filters which were not practical for changing light conditions at all, so I literally split hairs until finding this great value.
As for the test results: When enlarged %100 no softening effect at all even a tiny bit more defined!
All shot on the tripod at self-timer and live view to be precise (Nikon D750)
#1 image is without filter @ 1/800sec @ f/2.8
#2 image is with the variable ND filter @ 1/20 sec @ f/2.8 (ND 32)
#3 image is again with the variable ND filter @ 1/400 sec @ f/2.8 (ND 2)

It is so good and high-quality i loved it

Good a little vignette

Product: 58mm Variable ND2-ND32

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.
