Fits perfectly on an 82mm EF barrel. Beautiful finish! Happy with my purchase.

I originally bought the ND8, ND64, ND100 in 58mm for my Fuji digital to keep it all small but liked them so much I bought them all again for my Mamiya 645 in 67mm.... priced low enough so I dont need one set of 77's and step rings for others camera, a set for each camera so I always have them.

Would be nice if K&F did a magnetic hood you could slap on after the filters, cant find a hoods that work with them but so far so good they seem to resist flaring much better than some of my older Tiffens.

Quality is superb, been using K&F products for years. Once the lens cap is seated, it’s difficult but not a problem with its removal. That’s my Pentax 6x7 with the K&F magnetic lens cap. While hiking up Koko Head Stairs, the lens cap remained as I had my camera out, taking photos of the climb up. It’s a worthy purchase. I’ll be buying more of these soon for my other lenses too.

I've bought a few things from K&F Concepts over the past few months. ND filters, a Camera Backpack, and a tripod. The magnetic ND filters are wonderful (see an example of a long exposure with K&F Concept 1000ND filter attached), these make me very happy.

The bag I bought was very good for the cost (around £70, but have since changed this again as my kit size and level have changed a lot, but that's no poor reflection on K&F Concepts, I simply needed a larger volume.

The tripod was an unfortunate experience, I had some issues with it and returned it for a full refund., which K&F Concepts honoured without any fuss. Great.... I then received an email from K&F Concept's Customer Service Manager (Rina Kuromiya) reaching out with concern about my review of the tripod. I was offered a compensatory gift which I had a choice of either picking anything from their product range to the value of the tripod I purchased, or I could take a gift voucher of a set value. I chose to take the products from their range and have even more magnetic filters from them and I couldn't be happier. Delivered the following day!

K&F Concepts' aftersales service and customer care are amazing. A lot of other companies could learn a lot from these. Yes, I would highly recommend them and will be purchasing more equipment from them in the future. - if Rina Kuromiya is reading this, I thank you sincerely, and would be more than happy to be a product tester for K&F Concepts ;)

As a hobby photographer I was mind blown trying this effect for the first time. Can't wait to use it more. I don't have experience with other brands tho-

I took this out for a little testing. I was able to get some good 60 second exposures on a bright sunny day. The sun was around 2p and no clouds in the sky.

On a couple of the photos at the river there is a showing of some slight vignetting in the upper left corner. It is easy to crop out, but it is there nonetheless. It should be noted that the vignette occurred at 24mm and I did have a CPL filter covering the ND1000.

There "may" be some color casting as well. It could have been the angle of my scene, however, and the CPL might have interfered. I won't knock it for color cast.

The magnetic design makes this so easy to use. When stacking, it can take some extra care to remove some of the filters without removing all of them.

Overall, I'm happy with these filters. I searched way too long among what is available at this time, and ended up with these. I'm glad I made the choice.

I think this has to be as good of an nd-1000 filter as any and recommend it.

Easy to use, and renders good colors

Very good and practical.

Great optical quality—no color shift, smooth long-exposure results, and the magnetic system makes attaching and removing the filter incredibly fast.
