I have an ND 400 that I use for waterfalls etc but do not always want to block that much light so was looking for something a little faster Maybe an ND16.I have had variable filters in the past but have never been happy the dreaded Xs on the screen when you rotate or uneven colour cast across the screen.I saw the K&F advertised claiming that you did not get any of thease issues so thought I would try and they are great, very even light reduction across the frame and no Xs.I have the 77mm filter it is really well made there are stops on the rotation so it it easy to tell where the limits are, the frame itself is slightly larger that the 77mm so no chance of vignetting in the corners, the slight disadvantage of this is I can not seem to fit the filter with my hood in place but not a huge deal.Highly recommended.

Now, one might think that why would you spend almost £50 to buy this when there are similar products available for £10??? Well, if you are thinking that, then obviously you are not a pro photographer are you? You see, its the quality of glass that you pay for and the coating that goes onto it! The finer the glass is the better light transmission will take place which is the key here! So absolutely worth every penny as I've test run it and will include photos later to this review! Also was impressed by it's packaging as item like this requires supreme care !

I love this ND filter . I chose this for my a7iii camera. Very happy with the purchase. I can expose rightly now without cranking up the shutter speed under the bright sun light .

I was sceptical about this product with the price but this is a great ND. I haven’t done any ‘proper’ testing but from the footage I’ve shot with it, it’s 10/10. No noticeable colour cast or any vignette. I would recommend!

It's a very useful piece of kit to have. Very easy to use. Well presented.

Easy to use, very good range, very good for bright sunlight photography to take the edge off though not quite dark enough for very long exposures in daytime.Really well made, smooth to use and really useful quality case.

Was looking at the more expensive ND filters but glad I went for this very good results so far, needs more testing

I've been using this filter for a while now and I'm liking it. No X pattern at all. Useful range of densities; in bright conditions I slap a constant ND8 on under it to bring the variable density adjustment down to a useful range. I imagine it has a slight color-cast to it, like most do, but so far my footage has been very easy to balance with no obvious weirdness; if anything it often doesn't seem to need much correction. The filter's pretty thin and not too intrusive in use. Only real downside is that it has a different end diameter from the lens, so the lens hood (and cap) can't be used at the same time - but that's pretty usual, I believe. Overall it's a good filter and sure beats trying to control exposure with multiple single-density ND filters, as I was before.
