I bought this filter holder as an extension for the starter set because I wanted a 2nd one.
I have no complaints about the quality of K&F. At the same time, I use tripods, filters and surveillance camera from this company and I am very satisfied with them.

Screwing in the CPL is child's play and meanwhile I leave the filter in the 2nd adapter so that it can be used promptly and it stays clean.

I now use a large number of CPL, ND and GND filters from K&F in these holders and I am convinced of the system.

The filter and holder are great and the attachment was very easy. The picture quality is also great. Therefore a good recommendation for the price.

..and good value for money

Have tried other systems before but found them too fiddly to work with.
This system is so easy to set up your shot, change filters and recompose etc.
Absolute game changer.
The ability to buy extra plastic frames for your existing filters is a superb idea also.

100% recomendado

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.

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.

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.

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.
