The filter pack is well made and designed to be protected. The filter removal system is practical, pleasant to use and useful for controlling the high tones of the sky, etc. In my opinion, it will be very important to choose a metal filter holder that precisely blocks the mounted filters.

What to expect from this type of filter

Very good construction, all metal. It fits correctly.
The problem is the price, which is a bit high.

I informed them of these issues even though they were purchases made 18 months ago. They have since sent me a completely new holder with the missing part attached.

Excellent service. It's still worth checking when it arrives in case something else slipped through the cracks during production.

Gap between glass filter and filter holder. Not ideal if the purpose of an ND filter is to reduce the light entering the lens. Needs some work.

Well presented lookswell made pouch is nice touch oasis, t tried it yet for color casting but for the price I don't expect Lee quality give one a try

As the title suggests... Great metal filter holder. Excellent packaging, K&f, proves that it is a company that paints materials of excellent quality, no longer an alternative to the most famous filters, but first class! Recommended

A few years ago, I started beefing up my camera equipment. I had a Canon 5D Mark IV camera body, but didn’t have great glass. So, I started my gear journey by upgrading my lenses. I now have four amazing lenses including a 70-200, 24-70, 100mm Macro, and a Wide Angle lens. After I finalized my collection of lenses, I started looking at accessories I needed to accompany those lenses and came up with a short list of items that included high-quality filters. The problem I had was that I needed to be able have filters that works with all my lenses. Buying filters for each one of your lenses can get really cost prohibitive. So, one solution I found was to get a square filter with step-down rings. K&F Concept has a great option for this type of set-up so I gave it a try.

About a month ago, I shot photos at a wedding on a mountaintop in Tennessee. It was in the middle of the afternoon and the sun was super bright at the location of the ceremony. The venue was huge and I wanted to pack my camera bag somewhat light so that I didn’t have to struggle with tons of equipment. The square filter set from K&F concept was perfect for this type of work. The kit is lightweight and it makes it possible to use the one filter for several different sizes of lenses. During this wedding I was working with an 82mm lens and a 77mm lens as my primary glass. At the ceremony site, I had to quickly swap lenses and reapply the filter in order to get the shots the couple wanted. I found gaps in the ceremony where I could quietly and quickly change lenses and attach the filters without disturbing the event. It worked perfectly and even though some people might consider it cumbersome, I thought it was a lot easier than having to swap lenses and then screw filter into each lens.

When using these filters, I shot exclusively in RAW, but did not perceive any color cast from the filters. The mount is solid and the filter is well-protected by the soft lining in the case. It’s very easy to attach the mount to the lenses and in my opinion is actually easier to work with than individual filters.

I do feel like the lens adapter could fit a little more snuggly onto the camera lens, but I’m definitely not complaining about that and it is certainly not a dealbreaker. It’s just a tweak that could make the product even better than it already is.

One of the most appealing features of this product is its price. At £100, it’s much more budget-friendly than purchasing a single ND1000 filter. This is a great set-up for beginners and professionals alike.

The gray filter comes in a sturdy protective case and fits exactly into my Rollei rectangular filter holder. The optical properties do not reveal any errors. A satisfied customer thanks you.

Delivery was very fast. Unbeatable for the price... Everything is processed to a high standard. I can't confirm some criticism that the graduated filter is less foggy towards the middle. It was done very cleanly in my case. If the insertion should be a little difficult, then loosen the 4 screws on the filter holder a little bit and everything runs like butter! No colour cast on the filters! Great bags included... Polarising filter story, just screw an existing one onto the lens and then the filter holder on top. What more could you want without having to spend 400-500€? Full marks from me.

Having some experience with ND filters, I always worry about purple corners or dark spots. I took the set out today and got no strange colors. I love this set, it mounts nicely to my lenses with no fear of it falling off. The picture was taken at 11mm, 13 seconds shutter on my Canon 50D, I found K&F Concept when I wanted a good tripod which I found from them. Now if i need any accessories for my photography i look to them first.
