This square filter system is much better quality than the cheaper equivalents. Since the filters have frames, those are easy to handle, without smudges and scratches. The size is enormous (good for wide-angle) and the CPOL integration is definitely an advantage.

I suggest to try out the entire setup at home before using it for the first time (the attaching mechanism of the filter holder to the lens ring is tricky, make sure it locks properly, else you might need to fish for it in the lake...)

The quality of the build of the rings / holders is excellent. The filters themselves come in leather-like pouches. The image quality of pictures taken using these is really good.

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.

It's actually a great system:
The filter that comes with it is very well made and, in my lay eyes, has no color cast. The filters are tight, but not too tight, the clamping device for removing the filter system works well and the adapter rings that come with it are also good...

Overall, I'm satisfied and have now gotten more filters from K&F Concept.

SKU.1878 is a very versatile system and a quality product. The tab filters slide in and out of the holder with ease. So far no light has leaked out. I love that frame for my additional 100 x 100 and 150 x 100 filters get. It keeps fingerprints off the filter.

The company is located in Hong Kong. I would have liked to get extra adapter rings, but K&F Concept doesn't sell them separately, or so it seems. I contacted them through their website/email address and keep getting ads for their backpack. I was directed to get magnetic adapter rings, which are not for this system. It seems if you want to get adapters, you have to buy the filter holder and adapter rings.

This is definitely a product to buy. I look forward to taking pictures with it. It would be nice to have a wide angle sunshade.

Does what it should… and very well made

Everything as described. A great system.

It attaches easily and does not let direct light in between the support and the lens. I am delighted with it, very easy to put on and take off and the filters are of very good quality.
I recommend it for people who are demanding in photography, very good quality.

This is a good kit if you need a filter system that includes ND and polarizer. Image quality is not degraded with the included filters. The filter holder is sturdy and easy to install.
