These aren't cheap, but Lee Filters are a steal. The filter holder is superb and comes with several adapter rings which are £26 each from Lee. I don't see any appreciable color cast. So if you want to experiment with proper filters without breaking the bank these are a good buy. The filter cases are beautiful and the overall product presentation/packaging exudes quality.

I have not yet been able to justify using a more expensive filter system like Lee. I live near water and like longer exposures to smooth out the water for sunset shots. This makes the trick perfect for my use.

I used it to take long exposure shots at one of my local beaches and it works great with no noticeable color cast. My only reservation is the size of the filter. I use a Lee filter holder and have been told this K&F filter is compatible and IT IS BUT beware! It seems a bit thinner than the Lee filters and it can start to slide down through the holder. Luckily I noticed this before it slipped out completely and rotated the holder 90 degrees to prevent it from happening again, but this prevented me from combining the filter with a separate ND grading filter. I'm sure applying a tiny strip of acid free tape to two opposite edges to add thickness will solve the problem.

Having previously bought from K&F primarily at the photo shows, I was confident that I would be getting a quality product without the ridiculous prices of many photo gear companies. Having previously had a Lee filter holder that was damaged when I dropped my camera I found it a bit cumbersome so thought I'd try an alternative. Seduced by the price tag, I chose this product. The item arrived the next day as promised and I must say that at first I was pleasantly surprised by the packaging. Upon closer inspection I found the product to be well made, sturdy and very easy to use, much easier than the Lee filter version. The locking rings were also well made and fit for purpose...overall a very wise decision to stick with K&F.

Put off by the price of Lee filters and holders I decided to try the K&F kit. The quality of manufacture and packaging feels premium and with the Reverse Grad ND filter designed for morning landscapes, I haven't noticed any ill effects on my Nikon D750 images. The filter storage boxes are great. Just make sure you store the filter in the fabric to avoid scratching. The filter holder is beautifully made and finished and unlike one reviewer I had no concerns about how well the filter was held. The full set of adapter rings included in the price makes this a great value when using a range of lenses and a range of filters.

Much better than the bulky Lee filter holders. Filter seems to be working well so far.

Replaces a system type Lee filter when you need to adjust its ND filter to a reduction in brightness during a longer break. Polarization is a plus that works well

Excellent product with high quality lenses, especially in ND use.
great product
