Having purchased a square filter, I needed the mount to use the filter and found as usual with K&F Concept that it is well made. It was a little fiddly to work out how to fit the mount to the lens but once I worked it out this was easy and allowed the filter to rotate on the lens mount as needed.The adapters for the lens sizes are useful for this however they could do with a more suitable case for carrying with the mount as all are supplied within separate plastic bags. It won't be a big problem if you have a good sized back suitable for your kit and plenty of suitable pockets for the filters.I'm more than happy to recommend based on the quality but I'd urge improvement in the storage with a decent storage bag included for the lens adapters.

This is the second piece of photographic equipment I have bought from K&F Concept and in both cases the items have impressed me by their quality and value. The filer mount and lens adapters are made in well finished aluminium, are easy to assemble and use. I am confident that they will give me years of good service

Mostly excellent full metal build quality, except the filter holding part itself is plastic. Very good design and very simple to use. Fast to put on and off (quick release is awesome). I have faith in the build quality, though. I will update this review if it breaks.

K & F were kind enough to send me this product to review. It took a while to arrive, but when it did I was impressed with the quality of the product and the packaging OK what's it for? Instead of a gentle graduated area between the clear and coated areas there is a defined line, making this the ideal filter for sunrises and sunsets, especially where you have a flat horizon or a big sky. I didn't see any noticeable colour shift and it fit well with both my Lee and Siotti filter systems. There are some of the images I took with the filter on the K & F Instagram page https://www.instagram.com/kfconcept/ . Conclusion - a very worth while addition to any photo-bag in my opinion
