K&F ConceptSquare ND8 ND64 ND1000, 100mm Filter Holder with Round CPL Kit, Adapter Rings 67mm 72mm 77mm 82mm (X-PRO Series)

I have been very impressed with K&F Concept products over the years and have a number of the products in my Kit from Tripods through to Filter Systems such as these. Had been using a different system for a couple of years but when I upgraded to a full frame camera (Nikon D850) That smaller filter system Vignetted the 24mm lens. This was my first choice for the shortlist and eventual winner. It is giving me excellent results. The Build Quality is first rate and I am very happy with my purchase and will happily recommend the K&F Concept Brand to anybody looking for any camera accessory.

Excellent value for money. Well though out, made and engineered, comes in a nice box, all very well presented. Complete with adaptor rings to fit most lenses. No colour cast that I can see. Im very pleased with the filter kit and have produced good images. Would recommend K&F Concept Pro Square filter set to anyone not prepared to pay silly money for other brands.

Takes a bit of getting used to but the value of a top quality holder, ND filter and a circular polariser complete with several adaptor rings makes this a bit of a bargain. I can even use it on my 14-30 NIKon Z Len’s at 14mm without vignetting once positioned correctly. Pretty impressive bit of kit. The ND is excellent and neutral. Recommended!

Love the rapid release frame and the secure fit of the CPL, along with the easy rotation. No evidence of colour cast when stacking filters. Carry case is good quality also.

Brilliant kit haven't had any problems yet Some people say the quality is not good but I think you have to handle this with care.

It does its job as a protection but it makes the filter thicker and has to be removed before fitting its brand's filter mountNot so convenient

Exceed my expectations, its a really well made filter holder and set of filters and very easy to handle.10/10

It seemed a good idea... framed filters for protection and a revolving CPL that locked in place. However, the thumbwheel only turned freely when there was no CPL in place! As soon as it was inserted and the locking arm closed, the wheel constantly jammed. Hard to see exactly why but it appeared as if locking the CPL down caused a tiny flex, enough to make the thumbwheel touch the filter holder frame as it turned. I decided not to request another as I could imagine the problem might occur sooner or later with a replacement. Full marks though to Amazon's returns procedure.
