K&F Concept Square ND1000, 95mm CPL, Filter Holder Kit, Metal Lens Adapter for Filter 100mm Adapter Rings 67mm 72mm 77mm 82mm (X-Pro Series)

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.

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

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!

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

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.

Part of a brilliant photography system

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.

These are great filters and holder. Works with a large variety of lenses, I use this frequently, it never leaves my camera bag.

I purchased the K&F X-PRO Square system. I've used other filter "systems" and most work as expected. These filters fit for all of my Nikon lens filter of diameter up to 77mm (or actually 95mm on the mount). The material and construction is exceptionally well manufactured and well thought out in its design. The included manual is clear and well written for we English speaking/written folks at least. The adapting rings offer "just enough" purchase for screw mount to the lens, so be patience and carefully on the mounting them... could use a few more threads, I suppose. Mounting the 95mm polarizing (CP) is a snap - insuring you position the proper direction. Of course, you have two different ways to rotate the CP - using the handy knurled thumb wheel or to lighten the locking the full frame and/or from the full frame assemble.Now, since I did not give you ALL of this products 5-stars for a silly reason. The package and the "Storage Case" is over killing! Beautifully packaged, thoughtfully planned for the full system with space for growth. I/most have their own storage and transport camera cases(s) and most do not fill this beautiful storage case! I would rather have had another filter or a more spartan case for individual filter cases for my camera bag... as a trade for the case! For me, I found another small & padded case, for my new K&F bracket + the CP perfectly for my camera bag. AND I had hoped that the K&F offered properly protected for individual square lens w/frame separately purchased - but not with success.SO - it's not Perfect for my needs - though almost! Although this is my "first K&F product, I strongly recommend based on my first purchase!Greg Wilder

very good

O Produto é de excelente qualidade, chegou lacrado e muito bem embalado.Houve atraso na entrega mas devido a problemas de logística da Amazon.O vendedor foi muito atencioso e acompanhou todo o processo de entrega em atraso.Estou muito satisfeito com o produto e com o atendimento recebido pelo vendedor.

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...)
