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.

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.

I really do like this, made from good quality material and has a constant filter when varying the brightness of it. Would recommend.
