Buy several of K&F's filters, and while the brand disappoints when it comes to tripods, it more than makes up for it when it comes to filters. This kit is excellent, at the level of optical quality, and materials.
They have almost no color cast or chromatic aberrations, as well as no loss of image sharpness.
Highly recommended, especially since the ND1000 can go head to head with a Lee Big Stoper, and deliver better results for a fraction of the price.

The only drawback that it has, like all KITs, is that it does not come with a case to store everything (the K&F case is sold separately and is quite small for my needs).

This filter can be used in bright day light and I got all the size adapter to use the same filter in all my lens.

Welp, after getting this and not having a need for it until, of course, 2 days after the return window had closed, I broke it within 15 minutes of starting to use it. The seller graciously replaced it for me and followed up with multiple emails to check in with me. Still getting to know the product but initial impression is good and the seller provided excellent service.

Very happy with this. I'm just an enthusiast so this is just the right balance of quality and price. Slight color tinge but that can be corrected in post processing.

Came in quality packaging. Adapter rings were in individual bags but don’t see that as a drawback.

Hoping the glass is a better choice than resins that scratch...will just need to be careful not to drop them.

Needed a 10 stop Nd filter for long exposure and decided after reading reviews to buy this bundle instead of buying a smaller cokin p size to go with and older format Hi-Tech system I have. So glad I did.

I LOVE how easy this is to attach to the lens. I need to take more shots...but so far I am not getting any color cast. I shoot raw anyway so it isn’t a deal breaker. I LOVE the glass. Because the set screw was a bit fussy on my Hi-Tech holder, I opted most times not to carry it with me. I would rather fuss with composition and camera settings than fuss with a filter holder. This one will be in my bag from now on for sure. It’s simple to set up in the field.

Update 10/12/19. Put this set thru it’s paces on a photo shoot in Hawaii. Professional photographer was impressed with the 10 stop glass. No color cast. Easy to use. Got the 6 stop and 10 stop glass. Highly recommend both. I just need to get a 3stop to complete my set.

For the price you pay, the value you get is pretty amazing. Quality of the filters are really good with minimal color cast.Happy with my purchase.

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.

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.

Had a problem at first. The filter holder, closest slot to the lens, had a large space allowing a lot of light in and of course making the filter application useless. I contacted K&F and they were aware of the problem and asked patience as they were working on a solution. No problem. Within two weeks they sent me their updated filter holder and it now has a soft material that prevents any light entering. Perfect. The filter is a true 8 stop and glass not plastic. Great service, they stand behind their products, great filter, great price. What are you waiting for?
