This filter set is exactly what I was looking for. No plastic or light leaks here. It's very well manufactured and packaged. All light weight aircraft aluminum and optical glass. No color distortion in the filters. Everything fits nice and snug. If it didn't, then you would be inviting light leaks. Some reviewers said the fit was too tight. Not mine, it was perfect. Looking forward to using these on a daily basis. Great job K&F.

I haven’t had to use it at this point since I use a slow ISO film to begin with. Will use it in the future though I am sure.

Extremely professional and informative. Really helped me deciding on buying this set.

I was very surprised and pleased with the quality and clarity of the Graduated Neutral Density filter. My only concern was the filter fit tighter than i thought necessary and I was afraid I might break it trying to insert it into the filter frame. A little lithium lube in the grooves of the frame helped. I’ve included two test photos I shot to show the effect of the filter. Obviously the one with the darker sky was the one with the filter while the other had no filter.

A few month 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.

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.

Good product. High quality. It gives you what it promises. Recommended.

I bought this because the kit provides me with the variety of filter mounts I need to cover my lenses. I have not seen any problem with unevenness or color streaks in my images. Focusing is a challenge, of course, due to the filter density. The mounting rings attach securely to my lenses and the connection between the rings and the filter holder is solid. My filter fits firmly in the holder. I suggest inserting the filter into the holder "off camera." Screw the appropriate mounting ring onto your lens, and then "click" the filter/filter holder combination into place. While still holding the camera in one hand and the filter holder in the other, try to wiggle it or pull it off to test that it is firmly attached and that it won't fall off while you are shooting.

First time using an ND filter and I’m really pleased with the photo I took. The quality is really good. Thank you!

I have tried them all and I now use only K&F Concept systems! All ND filters have a color cast which can be fixed in post, HOWEVER, I have found K&F Concepts has the least. I use both the NANO Magnetic and the X-Pro Systems. . and they are THE BEST!!
