It takes a little getting used to, but the value of a high quality mount, ND filter and a full circular polarizer with several adapter rings makes it a bargain. I can even use it on my 14-30 NIKon Z Len 14mm 14-30 with no vignetting once properly attached. An awesome kit. The ND is excellent and neutral. Recommended.

Very easy to use system. The image quality is really good as far as I can tell. The polarizing filter works very well. The adapters allow the filter to be used on any lens here. Have never regretted the purchase.

Takes a bit of getting used to but the value of a top quality holder, ND filter and a circular polariser complete with several adaptor rings makes this a bit of a bargain. I can even use it on my 14-30 NIKon Z Len’s at 14mm without vignetting once positioned correctly. Pretty impressive bit of kit. The ND is excellent and neutral. Recommended!

This is a good kit if you need a filter system that includes ND and polarizer. Image quality is not degraded with the included filters. The filter holder is sturdy and easy to install.

I tried it and wasn't disappointed, easy to use but was too big to carry around for my type of photography unless you use only one lens, but it's too much headache when you keep switching lenses.

So i returned it and went with the magnetic filter from same brand which is perfect for me.

Love the rapid release frame and the secure fit of the CPL, along with the easy rotation. No evidence of colour cast when stacking filters. Carry case is good quality also.

This is a very versatile system and a quality product. The tabbed filters slide in and out of the holder without difficulty. So far, no light leaks. I love the ability to get frames for my additional filters, 100X100 and 150X100. It keeps fingerprints off the filter.

The company is based out of Hong Kong. I would have liked to get additional adapter rings, but the company does not sell them separately, or so it seems. I've contacted them via their web site/email address and keep getting ads for their backpack. I was referred to get magnetic adapter rings which are not for this system. It appears if you want to get adapters you need to buy the filter holder and adapter rings.

This is definitely a product to purchase. I look forward to shooting pictures with it. It would be nice to have a wide angle lens shade, but then, you can't always get what you want.

I bought the rectangular filter set directly from K&F.
Since I worked with screw filters in the past and had the problem with vignetting when screwing several filters on top of each other, I wanted to buy a rectangular filter set for a long time.
Since the sets from NISI, Haida and other well-known manufacturers are very, very expensive, I was looking for a cheaper alternative as a hobby photographer.
When I saw several reviews on YouTube, my decision on the set from K&F which is half cheaper than that of Haida and CO.
I have absolutely no regrets about my decision so far.

The filter holder is very high-quality and well thought out.
I particularly like how the polarizing filter is attached to the holder and how it can be adjusted using the small wheel.
The filters themselves are made of optical glass and show no color cast and are also well coated.
It should also be positively emphasized that the filters are provided with a plastic frame with a tab.
This allows the filters to be inserted and removed without annoying fingerprints.
It comes with a bag to store and transport the holder and filters in it.
Various adapter rings for different filter thread diameters are also included.
As a landscape amateur photographer, I no longer want to miss out on the advantages compared to screw filters.

I have a clear purchase recommendation for amateur photographers and professionals!!!
I wouldn't have expected such excellent quality for this price.
It's amazing what K&F delivers here.

Perfect product that adapts really well to all lenses! This allows you to have only one support. Very good quality with the storage pouch. I had lost a screw and the after-sales service was very responsive and they sent me back a batch of screws.

The system with the CPL filter mount beats anything I've used before. The mounting of the bracket is also easy by hand. The quality of the filters themselves leaves nothing to be desired. This makes filter photography simply fun!
