I have used ND grad filters for years on my SLR and DSLR cameras. I love scenery photography as opposed to portrait so always looking to sort out the difference in the light between the horizon etc. I live near the sea les that 300m away and walk along the cliffs regularly and don't take my DSLR with me when walking the dogs but always have my iPhone so any unexpected scenes are normally captured using the iPhone. This ND grad filter will come in useful. It fits over the lenses of my iPhone and helps sort out the difference in the light. Once clipped on it is easy to rotate the bezel to the setting you want using your finger. You have to ensure that you do not go past each of the stops or you will get leakage. SO my advise is to check before shooting that you are at the required stop. The other great thing about this filter is that it unscrews from the clip holder and can be screwed onto my 52mm lenses..Bonus... All in all this is a great little filter that I will carry around with me when out walking the dogs. We have a dog walking bag which has Poo Bags and drinking water etc so it sits in the side pocket of the bag in its case. so it is always there if we get a lovely sunset or something really nice to photograph on the sea or beach.. Get little gadget well worth the money highly recommended... As soon as we get anything really nice I will update this with the images...

At the price of Lee filters and holders, I decided to try the K&F kit. The quality of manufacture and packaging feels premium and with the Reverse Grad ND filter designed for morning landscapes I haven't noticed any adverse effects.

These aren't cheap, but Lee Filters are a steal. The filter holder is superb and comes with several adapter rings which are £26 each from Lee. I don't see any appreciable color cast. So if you want to experiment with proper filters without breaking the bank these are a good buy. The filter cases are beautiful and the overall product presentation/packaging exudes quality.

Put off by the price of Lee filters and holders I decided to try the K&F kit. The quality of manufacture and packaging feels premium and with the Reverse Grad ND filter designed for morning landscapes, I haven't noticed any ill effects on my Nikon D750 images. The filter storage boxes are great. Just make sure you store the filter in the fabric to avoid scratching. The filter holder is beautifully made and finished and unlike one reviewer I had no concerns about how well the filter was held. The full set of adapter rings included in the price makes this a great value when using a range of lenses and a range of filters.

You can't argue with the quality at this price point. A little tight for my Lee filters but the slits eased with use.

Not the best out there but for the price you can't go wrong. These filters are a lot cheaper than Lee etc but they're not too shabby in comparison and work well with less color casts than I thought - easy to correct in post-processing. Inexpensive items, why pay for a name when these are almost as good.

Replaces a system type Lee filter when you need to adjust its ND filter to a reduction in brightness during a longer break. Polarization is a plus that works well

I’ve been wanting an ND Grad filter for a long time, decided to go for the K&F as all of their other items are great value for money,
I wasn’t disappointed when I tried this,
