The filter is exactly as described,easy to fit, feels well constructed and comes in a sturdy case.As far as I can tell it does not add any innacurate colour cast as some cheap ND filters do.I bought a size to fit my largest Olympus pen f lens( which it does with no problem) and I purchased some low cost lens ring adaptors so that I can use it on any of my lenses(I did the same with a good quality polarising filter).

I shoot vlogs and wanted to experiment with manual settings outdoors; and it was suggested by other Youtubers to try using a variable nd filter for video shooting to help get a more cinematic look. I didn't know what to expect and didn't want to drop too much money so I gave this one a shot. I bought this particular fader because it was available and recommended by Amazon. Honestly it works very well. I've used it on video shoots and it helps me get the exact settings I want. I can easily get the fully open aperture and low ISO in broad daylight. Being variable I just have to rotate to change the setting rather than changing separate fixed nd filters. The image quality looks great as well, very sharp. I'm not sure if there is any color change as I don't notice it. The only thing I wish it had was some indicator to tell you what density it is at other than just line markings. But it isn't a deal breaker since I just rotate until I get the right exposure settings anyway. Just be careful of rotating past minimum or maximum as you do get that 'X' across the image that people talk about. I think it's prevalent for all faders anyways. Also I wish I could put a lens cap on it since the outside isn't threaded so the cap doesn't stay on. Other than that the build quality seems very good.Overall it's a great filter to experiment with and for its low cost it's definitely worth trying out.

Great gift for a film student.

For the price this is a great nd filter, The only downside is that you get a slight green colour cast but nothing you can’t fix in post production, otherwise great filter.

This is the 3rd 58mm I have bought, the other 2 were a lot more expensive. This holds up to them equally in nearly every way. There is no stop on either end of the throw, so without looking it's had to guage at what stop you're shooting, and it is labelled min to max, rather than by stop also. After a bit of playing though, it is as good as it's more expensive rivals. Very affordable, very affective. Would recommend

A good budget ND Filter to Get you started.This is a decent starter ND Filter, it gets the job done and I didn't notice a huge impact on image quality when using. It's very useful being able to have one filter on and simply turning it to adjust the intensity.One negative is that at the highest ND setting you do get a X shape appear on the image, this is common with most variable filters and makes it unusable at the higher intensities.However for the price you can't go wrong with this even if you only use it for the lower ND intensities.Definitely recommend for beginners who want to learn more about filters and experiments until you have the confidence to drop a much larger sum of money on high quality filters.

We bought this lens our son. He loved it so much, we bought another one as a birthday gift for a friend!

I guess for the price this is ok. It does work and is sorta smooth but compared to more expensive versions it is far less smooth feeling. Optically I cannot say if this KF model is ok but I would say as a back up VND it is decent. When you twist it there is a bit of a grinding feel to it. I am not sure that gritty feel will go away in time or not. Now compared to housebrands I have tried from large photo stores I would say this product is better and cheaper. BUT compared to a Tiffen for over $100 this KF is not quite as smooth. Optics don't know.

Love it works great. However! if you have a 58mm thread you will need to buy a 62mm lense cover as the front thread is larger than the back thread and the 58mm will not fit. Just a helpful tip when looking into buying this product.

This lens showed up at my door in just under 12 hours! It was incredible! The quality of the images with it are great it it's the prefect lense for motion blur.
