There was a problem filtering reviews right now. Please try again later.
I wanted to take some smooth pictures of waterfalls and saw this variable ND filter with good reviews. On the item description page, there's plenty of warnings to make sure you buy the right filter thread size for your camera, which seems pretty obvious. However, they don't mention that this ND filter is poorly suited to wide angle lenses. For reference, I had paired this filter with a Zeiss Touit E 12mm f/2.8 mounted on a Sony a6500.
After coming back from vacation, I realized that many shots I took with the filter mounted had pretty poor light uniformity. I did notice while taking the photos that rotating past a certain point produced noticeable unevenness, but the effect was less/not noticeable when I turned the ND down. However, upon checking the images on a computer monitor, it was obvious that the brightness is not uniform.
I asked the seller about the issue and copied/pasted their response below:
"Darkness is a common issue with wide angle lenses and variable ND filters. Physics limit the capabilities of variable ND filters on wide angle lenses. When you enter the edge of the max range,the darkness may appear on your image. Because you are using it beyond its capability according to the laws of optical physics,which will inevitably cause this phenomenon. could you try to turn down the degree until the black fade away?"
So I guess I'll chalk this up to inexperience on my end. Still, I'm docking 2 stars because it's not documented anywhere on the item page which focal lengths are supported, which can lead to some mislead some buyers. Also, it's not really feasible to tell if there is a slight amount of uneven brightness while taking the shot or previewing in camera. Thus, you can end up with a bunch of bad shots that you wouldn't know about until you get back to a monitor.
I took off 1 star because I noticed that when you shoot into the sun or a light source (which as a nature photographer can be hard to avoid), there is a slight ghosting - almost a reflection of the filter - that appears on your images. In the first picture I uploaded, I had to edit the ghosting out of the flat water. Using some type of shade seems to help, but now that’s one more thing I have to tote with me when I go...hence, minus 1 star.
Other than that one issue, this is my go-to filter now for shooting waterfalls or any water based scenery. I love it!
I didn't really get the chance to mess with this ND filter until I arrived at Letchworth and wow was I blown away! The crisp rolling ring and the crisp shade of black make this such an incredible product. So worth the price! I'm blown away by how it doesn't degrade the quality of my captures my lenses can get.
I love long exposure now. With my lightweight tripod and my filter, I can only grow.
I included a picture of a covered bridge in Cuyahoga Valley National Park taken with this filter. It was a eight second shutter speed.
I should have tested it more when I got it because now the 30 day return window is over and I'm stuck with a pretty much useless lens.
Do not buy!

My usual use for NDs is taking photos of moving water, mostly waterfalls, using the ND to smooth out the water to give it a misty/milky look.
Often cheap filters are made from plastic and resin, but these K&F filters are metal frame with glass elements which is a great bonus, they feel nice and solid.
The filter was slightly larger than expected as it's advertised as 'slim' - but there was no vignetting evident. The action of turning the filter to adjust the strength was nice and smooth with the right amount of resistance.
I was happy with the results from the test shots I took of a local waterfall, the ND did the correct job. There was very little colour cast that I could see, nothing that would be noticeable to the eye for most people, I shoot RAW so it was an easy fix in post processing.
Full strength did produce a stronger cast, but i would suggest buying a dedicated 10 stop if you need this level of ND darkness.
The only reason I've dropped a star from this review is because of the lack of a scale on the filter, this makes it difficult to measure and repeat settings when moving around, or shooting at a different time. An element of trial and error is needed - which can add time to getting the right shot. Hopefully K&F will rectify this in the near future as it's an easy update.
Overall, this is a great piece of kit for the price if you want to experiment with slowing the shutter down in daylight without needing multiple filters or paying out for high end equipment straight away.
**I received a discounted product in return for this review, but the above review is open, honest and unbiased**
This is the perfect md filter if you are running and gunning! No need to change filters over with this one.
I find it so helpful when I'm wanting to capture long exposures and when I'm filming this is a god send.
It's nicely packaged and comes in a little carry case with a branded cleaning cloth.
I'm very happy with my purchase and it does what it says on the tin! A very high quality Nd filter!
