K&F Concept Square Filter Kit ND1000 + GND8 + Metal Square Filter Holder Set SNJ51T

Arrived a day before scheduled delivery, BUT _no_ notice it was being delivered today and we were thinking of going out to enjoy the sunny day! Before you rip the inside black & orange boxes apart: the boxes can be opened from the front pulling from the bottom front edge. Very well-packaged and product presentation! Following instructions within, screwed in the lens filter adapter first, then clipped the filter holder to that. Ring edge away from the orange filter holder tab must be edged in at an angle first, then leveling the filter holder, push the tab to finish the placement. Easy! Practice a few times before going out since IF not mounted correctly, it'll feel as if the filter holder is in place but still isn't. My older 100x80mm filters fit also, so I can still use older filters as needed. Box cutter placed in pictures for size comparison. Will update as necessary when I use it out in the field, BUT I can already see using filters in my future will be a LOT easier and enjoyable!!!

This is the real deal in terms of money and quality !!! Great design, look and feel. Comes with a soft pouch which is nice ,i use this nd on my miami trip With my 16-35 it works fine , this is just a raw files and you can say a test shot with two different wb,

This is the second one I have bought. Both have been great! And the customer service was excellent!

For such a low price, my expectations weren’t very high but boy this product delivers. For the price of a single screw on ND1000 filter you get a holder plus a 100x100mm ND1000 filter.Attaching the filter holder is simple: simply screw on the appropriate adapter from the supplied adapters, then snap the filter holder on by pulling back on a lever. Then slot the filter glass in one of the two slots and you’re ready to rock and roll.The holder holds the filter glass securely so there’s no worry of it slipping out, regardless of orientation. The only potential finicky part is attaching the holder to the step up ring — you’ve got to ensure that it’s actually secured, because it may seem secure but actually isn’t. After a little practice, you get the feel, easily.As for picture quality, it’s very good. Little to no color shift that I can see. Great clarity with no distortion that I can tell. It appears to not vignette at 16mm on my Nikon 16-35 f4, though I’ll have to doublecheck. Absolutely great value for the money.And as I mentioned earlier, there are two filter slots in the holder, so you could potentially stack NDs, or stack an ND and a graduated ND, or whatever. One thing that would have been nice would have been a way to also use a rotatable circular polarizer, but for the low price, I’m not complaining. Might end up picking up a square circular polarizer for when I’m shooting over water.All in all, in you’re trying to get into long exposure photography and want to try 100mm filters without breaking the bank, yet still get great image quality, this is the one to get!

Very happy with this. I'm just an enthusiast so this is just the right balance of quality and price. Slight color tinge but that can be corrected in post processing.
