K&F CONCEPT 49mm True Color & Ultra Low Reflectivity ND2-32

Review
I really like the quality and performance of this ND filter. It fits my 50mm lens (49mm diameter) perfectly. The side paddle make it very easy to make granular adjustments to brightness to allow you to "slow down" your lens to help with brightness or motion (like water). The case is great, though overly large (takes up lots of room in your camera gear bag). I can't wait to give it a more complete workout for upcoming trips.

Recommendation
I do recommend this lens, super high quality.

I tried out this filter on an E-mount Tamron 150-500mm lens and was quite impressed. On an overcast day with the camera set at 150mm, F9 and ISO 400 for all pictures, a filter ND setting of 2 required a shutter speed of 1/3200 for the correct exposure. With the filter set at ND 32 the shutter speed was 1/320. There was no notable shift in any colors and no other aberrations introduced including vignetting.

The build quality seems very good, with a super smooth feel when changing the ND. The action is so smooth there is really no need for the massive orange tab to adjust the filter. Fortunately, the big orange tab can be removed with a Torx bit, which I did to allow using the lens hood for my Tamron (see photo) with the filter on. One last note, threading the filter onto the lens feels too tight and the filter does not easy spin on - giving it kind of a cheap feel. But overall, I an very happy with the filter.

K&F Concept keeps proving why they’re such a reliable brand for affordable, quality gear. This 82mm VND is smooth, accurate, and performs like a filter that should cost a lot more.
In my test shots, I saw no “X” cross pattern, no dark edges, and no weird color cast. That’s a huge win if you’ve ever fought with cheaper filters that ruin your shots. The large thumb handle is another nice touch—easy to find and adjust without taking your eye off the subject.
Overall, this is a well-built, dependable ND filter that’s perfect for both photo and video work. If you need a VND that just works without surprises, this one’s a solid pick.

The Good:
-Very easy to use
-Fits perfectly
-Reduces yellowish hue

The Bad:
-None

The Bottom Line:
I’ve been taking more photos with my Canon Rebel T7 and this K&F lens filter is great. Since I take a lot of pictures in the day under less cloudy skies, this filter really reduces the yellowish tone from the harshness of the light. The lens filter fits perfectly and is very easy to use. Overall, I would recommend this lens filter for its fit and performance.

Not only is this filter solid, but it comes with a great case to keep your filter safe.

The ND change is fantastic and I wasn't really seeing any weird vignetting or anything strange from the filter both in the edges nor center like some other ND filters.

The filter also has a little handle to turn the filter to adjust exposure.

Super happy here.

I'm not a professional, I only have two decent SLR cameras with decent lenses, and I mostly photograph landscapes and animals on vacation. Unfortunately, I use this equipment far too rarely in my free time...but I think I can give a useful assessment of this filter here.

I've been using K&F filters for years and am consistently satisfied with the quality.

This concept of an adjustable neutral density filter, however, is completely new to me.

So far, I've only used neutral density filters as static filters with values ​​of 4 and 8. I'm generally comfortable with them and can achieve the desired effects and results. For example, I can darken snowy beaches completely bathed in sunlight to a level that's easy for the camera to handle, or enable longer exposure times in light/shadow landscapes. You can also achieve good effects with flowing water with it...but every ambitious photographer knows that.

This adjustable neutral density filter actually works like a polarizing filter. It slides very smoothly, and the integrated grip distinguishes it positively from my polarizing filters.
The 77mm thread is very precisely machined. Inserting it into the lens is absolutely no problem.

With the filter attached, it might no longer be possible to use the lens hood. It would even still work for me...but inserting the filter and operating it is a bit cumbersome. So I simply leave the lens hood off...

The filter is completely color-neutral. This can easily be verified with a few test shots. The adjustability is truly fluid, meaning it's stepless.

I'll probably never need the maximum setting of 32...but as I said, I'm not a professional.

Unfortunately, the weather right now isn't ideal for a comprehensive test. So I can't upload any meaningful sample images. I'll be happy to provide them later...

First pictures in the forest with light and shadow, or pictures of the (unfortunately gray) sky on house facades and trees, are promising.

The filter comes with a decent case and is reliably protected inside.

My conclusion: a useful addition to my equipment. How often and for what purposes I'll actually use it remains to be seen. I'm off to Cyprus soon...let's see what it can do there...

Pictures to follow...

This filter is a great addition to my photography filters. It easily screws onto the lens and lets me shoot in very bright conditions, which is helpful for outdoor photos and video especially in bright daylight. The glass itself looks to be high-quality, and its coatings do a good job of keeping reflections down and resisting fingerprints. Everything I've used from K&F has been high quality and this is no exception.

At 1st I liked the Orange handle or knob for rotating the filter to various ND stops but after a while it seems that's not really that useful. It looks nice and may make it easier to see where your top end to bottom end ND filter is but didn't really add much to it in the end.

The quality of the filter itself is nice and it comes with a really nice leather like case for storage which in itself makes this a very nice filter setup. The aluminum outer portion has knurled fins to make it easy to grab and rotate along with the orange knob.

Overall its a nice filter and the true color works better than without a filter. I have only used a few times and it works great so far. Very happy with the filter but it is quite expensive

I'm using this on my RX1RIII and it's simply perfect! It doesn't add much weight to the camera so I don't mind keeping it on there all the time, it has minimal to know perceivable vignetting, and most importantly, no dreaded X-pattern. It doesn't shift colors in any crazy directions making post processing of stills and video easy. If you're not wanting to spend Nisi/B+W type of money, these VNDs from K&F are a fantastic choice!

For expanding your photography creativity, the quality, functionality, and adjustment are on-point. Seems clear, polarizes well, and minimal vignetting. A little pricey, but it's a clear winner over some cheaper ND filters I have.
