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!

returned as wasn't happy with the overall sharpness of any image shot through this, edges of items within the shot were soft going to have to spend the money to get the quality needed

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.

Update new filter arrived and thread is good so looking forward to trying it out great service in replacing faulty goodsThe thread was so poor could not connect the filter to the lens. Also once fitted the size of filter makes it impossible to fit or remove lens hood

For a recent trip to the Middle East I wanted to purchase some additional gear for my Sony A7III. I picked K&F Concept because after my research I understand they offer value for money and good quality products.I got the 77mm version of this Graduated Neutral Density Filter along with their step up rings. The filter is a 5 stop filter (ND2 ND4 ND8 ND16 ND32).I have to say, firstly I was impressed by their packaging and the protective case the ND filter came in.After taking the ND filter out of the case you can just tell it has been made well, it has some weight to it which makes it feel premium. The adjustable slider is also very smooth and has the right amount of tension in my opinion.I managed to test the filter on a few occasions throughout the trip and I have thoroughly enjoyed my experience in using this product and to top it all off I didn't experience the dreaded 'X' effect whilst using this filter.
