This is a serious piece of kit if you are a professional photographer or even if you are fairly new to photography and want to ramp up your skills.
This incredible filter allows you to select from a range of filter options in order to add some darkness to specific parts of an image. For example the sky can look darkened whilst the rest of the picture is bright.
It gives a stunning effect and can really enhance any picture for a professional look. I’ve played around with it over the weekend and it is fantastic. It’s pretty amazing at how much of a difference lighting can make in a photo. Very happy indeed.

works perfect and high quality

Excellent medium-high quality filters. They are totally recommended.

Apart from the fact that it is an excellent product, the customer support is absolutely great, I have rarely been treated so reliably and friendly, big praise.

I bought these Freewell range of filters as they were one of the first to use a magnet rather then a thread to attach the filter to the lens, and this makes life so much easier when swapping filters

Love the fact that I can change filters without the need of having to scree these on, especially when wearing gloves on a cold winter day

Good Product, I am satisfied!

Easy to swap quality filters. Only downside is the lens cap will take the filter off when you remove it (if you put the cap over a filter on your lens), but other than that, I love the ability to throw filters on and off quickly. I can also use my older screw-on filters on top of these, so I can stack a magnetic CPL, magnetic ND16 and a screw-on ND1000 for a long exposure shot (as an example).
They are very good quality with no more color shift than any other filter on the market.
Also as a tip, I bought the largest filter I needed and bought the freewill step up rings for my other lenses. This way I only needed to buy one set of filters. The step up rings from Freewell have the magnetic base built in.
One last thing, the filters now come with 2 base rings, one with a UV filter and one that is just the open ring (no glass).
When I received the ND filter I could not get it to work right with the open base ring that I attached to my lens. Then I noticed the UV base ring was already attached to the ND filter in the package (they are so thin I could not tell), so I was trying to attach one base ring on top of another, so I just separated the UV base ring and put it away and viola the ND filter fit perfectly into the open base ring. I do not like putting extra glass on my lens, so I dont use UV filters.

Due to a neurological issue I'm using a bridge camera - a Sony RX10 IV. I love it but have been looking for a solution to area blow out and read that a graduated neutral density filter would help. I was offered the "K&F Concept 72mm HD Soft GND8 Lens Filter, 3 Stop (0.9) Soft Graduated Neutral Density Filter" and selected it as a trial. The lens seems to be of good quality especially for the price. It didn't distort the images and the final photos were sharp; it was easily screwed onto my camera.

Very satisfied. It brings even more momentum to my pictures.
