K&F Concept 67mm ND2-ND32 Filter Neutral Density Variable Filter ND2 to ND32 for Camera Lens NO X Spot,Nanotec,Ultra-Slim,Weather-Sealed

Great product and does what it says. Easy to clean, i just usually blow air at the dust or you can use a bulb air puffer or a soft cloth. Now you have to balance your expectations when using variable screw-on filters like these. If you’re planning to take landscape photos where there’s a foreground element and the sky at the back, then in that case it would make more sense to buy into a square graduated filter system of your choice. But with all that aside, this is a great product, specially when you consider the affordable price.

Package arrived in just 4 days! Owned a couple of K&F's (ND 8 -128 and one fixed). All of them work great. Best result is between the ends. Don't push to max, just a wee lower. Works great for my a6400 and Sony 18-105 and Sigmas f1.4's

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.

Increíble producto la calidad de sus cristales es increíble no te genera la famosa viñeta, solo que a veces se siente un poquito flojo al ajustar los pasos pero la verdad es que por su precio y calidad está increíble súper recomendado!

Makes noice while screwing the filter to the lense. Even left a scratch on the lense thread.

The filter is a little tricky to get on with the lens hood, but if you put the lens hood on, with the filter down inside the hood, then screw on the lens filter, it works, but it's hard to make to work. The lens cap however doesn't fit. The performance of the filter is great, good for video during the day shooting log with my R7. Can't beat the price. I leave it on my lens now all the time. Has a really nice look to it.
