Great!
This is high quality ND filter to reduce the exposure in photography. I'm using the 67mm of this filter. It's multi-coated, so looks solid and high quality. It is a variable ND filter change from ND2 to ND400 in 9 steps.
Great!

Great VND for the price. Easy to use. Will help open up your lens and save your lights
have had this VND for a little over a month now and I can say it is a very useful bit of kit to have in the bag. Natural light shooters will appreciate being able to cut down light to shoot at wider apertures, and strobists will like that plus the ability to stop down ambient light to match strobe lighting without having to go into HSS. I haven't tested it with video, as I primarily shoot stills, but for the film shooter on the go, this would be very useful. Quality seems to be there, its a metal filter, and the glass elements seem well constructed. I was able to count hairs on heads, so the effect on a cameras resolving power seems to be little to none, which is good. Autofocus on the a9 and the 70-200 GM seemed to be fine It comes with a little plastic case, which fit nicely into the bag without taking up too much space. The adjustment of the filter is obviously easier without the lens hood, even though the 70-200 GM has a built in access for adjusting VND's I did a quick backyard test with my son to illustrate the exposure versatility of VND and it does indeed provide 9 stops of exposure adjustment. Having that flexibility is useful for many different types and styles of video and photography. I provided a composited image showing the 10 frames I shot. I also included an image where I used the filter to allow me to slow down the shutter, and turn the water circling around a boat into something with a more dreamy, or painterly effect. The last shot is using the reflective blue tint on the filter element to reflect the clouds over the image of the boat to create a double exposure look, the VND allowed me to only cut some of the light and still create a reflection, opposed to using a cell phone, or a mirror which are totally opaque. to do this, i took the VND off the lens and angled it in front with my hand until I got the composition i wanted. Few tips for people new to using filters or VND's, don't over tighten the filter onto the lens. These things are made to be lowprofile and have fine threads, so go easy. There is a tick mark on the non-rotating part of the VND. Make sure you adjust the rotating marks on the filter off the position of the non-rotating tick mark. There are no clicks, or hard stops, just a fluid movement, so keep an eye on your adjustments if your moving around a lot. lighting conditions can change. Lastly, you shouldn't be using this indoors, unless you are trying to hss lights or purposefully cut lighting. VND's of all kinds typically don't have a neutral setting, so they are always cutting down some amount of light. Typically, indoors you want to be gathering as much light as your can. So when you come indoors, pop the filter back in the bag. Overall, I would recommend this VND filter. There are much higher priced VNDs out there, but if you're here, then your probably not looking at the $200+ VNDs on the market. This is a good filter and will get you great results, plus the blue tint on the glass element looks really cool. I have really enjoyed shooting with the VND, hope you like yours

Think of it as sunglasses for your camera
heard a lot about ND filter but not ready to buy the really expensive one off the bat so based on the review I decided to go with this one. For the price the quality of the glass and coating seems amazing. I never had one so nothing to compare it with. I love that it has a variable adjustment for it, seems pretty neat. Having never own one I decided to go out to the local fishing pond and takes some pictures. I upload 2 photo one with the filter one without and i'm just amazed. The picture I uploaded are unedited right off the camera with and same settings. It brings a lot of color out with the filter. Pro: • Very inexpensive filter with amazing result • Great for anyone who is starting out • Quality glass and coating • Variable ND glass • Neatly Packaged Cons: • Non at this time very happy so far If you are just starting out and don't want to break the bank and just curious on how these things work with your camera i highly suggest getting these. For the price what you got to lose. If its something you might be interested in doing more with your photography skill by all means invest in the more expensive lens but as a hobbyist these are great.

From 1-5 stops, there will be a slight X cross for lens under 24mm. An X cross will appear at the highest stop and can be removed by rotating the filter ring, which is a normal situation instead of a quality issue.

As K&F Concept ND2-ND400 filters adjusts the amount of light that can pass through with polarizing glass, a colour cast can't be avoided for all the variable ND filters on the market. However, K&F Concept variable ND filters are made by the best coating technology, which reduces the effect of the polarizing film on image color. *Based on our professional test, the colour cast of K&F Concept ND2-ND400 filters is around 290k while the industry standard is 500k.

A
To avoid dark corners, K&F Concept ND2-ND400 filters are designed in ultra-wide construction so the front side of the ND filter is one size larger than the camera lens. It is recommended to use a lens hood of a larger size.

First, K&F Concept ND2-ND400 lens filter allows changing shutter speed based on the effect you want with the best sensibility and the same aperture. Second, K&F Concept ND2-ND400 lens filter allows creating a blurred background with a large aperture while the shutter speed remains the same. Third, K&F Concept ND2-ND400 lens filter is designed to prevent overexposure and maintain image purity and quality at the same time. *Like a zoom lens, the variable nd filters are suitable for multiple shooting situations. If you're looking for perfect image quality, a fixed ND filter is recommended.
