Had a problem at first. The filter holder, closest slot to the lens, had a large space allowing a lot of light in and of course making the filter application useless. I contacted K&F and they were aware of the problem and asked patience as they were working on a solution. No problem. Within two weeks they sent me their updated filter holder and it now has a soft material that prevents any light entering. Perfect. The filter is a true 8 stop and glass not plastic. Great service, they stand behind their products, great filter, great price. What are you waiting for?

Too bad that the accessories to reuse the filters that we already have are so difficult to order.

I've used it a few times with an exposure calculator and it was pretty accurate.

Great filters for time lapse landscape/water photography.

This is tough to beat. Not only do you get a 100mm GLASS (not plastic) 10-stop ND filter, but you also get the filter METAL mount and multiple METAL lens adapters. Even if you need to buy step-up/down adapters because the ones included do not fit your lenses, this is still a bargain. Even though this comes in at well below the price of other 100mm 10-stop filters (without the mounting system), it performs excellently.

My unit doesn't produce any noticeable color cast, but I also shoot solely in RAW, so a color cast wouldn't be an issue anyway. The case for the filter is firm, so I don't worry about it very much when it's in my camera back, and the soft lining keeps the filter safe from scratches (so long as nothing coarse gets inside, of course). Better still, the filter mount features a second slot should you wish to use additional 100mm filters (e.g. graduated filters). I point out the size because this is the "standard" in these filters, rather than the more common 80-something mm ones you see in comparably-priced square ND filter bundles that use smaller, cheaper plastic filters instead.

The only issue I found, and this is really just nitpicking at this point, is that the filter mount never really feels very securely attached to the lens. The filter and mount won't fall off if the camera is moved or tilted forward, but the mechanism that attaches the mount to the lens adapter could be a bit tighter fitting in my opinion. Nevertheless, great product at a great price. Anything "better" will be considerably more expensive, and even then, how much "better" will it be?

First time using an ND filter and I’m really pleased with the photo I took. The quality is really good. Thank you!

Really good filters. For the money and got quality

Nice finish with a excellent thumb lock. All metal parts that are machined to fit perfectly. Very nice product with first class glass. Made in England.

I loved the quality of the materials, all metallic. I looked at many kits but they were all plastic and this one caught my attention especially with the comments. The truth is that it was a success because every other similar kit doesn't fall under 300€.The nd1000 optical filter is made of glass and gives a very good quality. The only thing I noticed is that it loses a little saturation and the white balance is a little bluish, but when processing the RAW it is easily fixed. You increase the colour temperature and saturation and you're done!!! (I use a Canon 80d + 16-35 f4 is). I imagine every lens will be different.Attached a few photos so you can see the difference with filter and without filter. Exposure time on the photo with the 30" filter.If you want to start in the world of filters, don't even think about it for this price. Excellent results.

It's made from really high quality leather and has a magnet to keep it closed. There is a belt loop which I will probably never use, but there is a metal frame to clip onto your bag which I will probably use.
