While I got it through VINE, I would still say that this is a very nice quality lens for the actual price! I have only taken quick test shots, but it seems to do what it is supposed to do. I am still getting used to the different ways to creatively compose my photos, but liking what these ND filters can do!

This is a nicely manufactured set of three ND (8, 64 & 1000) filters made by K&F that comes in a slip case perfectly suited for protecting the filters in your camera bag. Like other K&F filters that I've bought, the filters are well made, multi-coated glass, and solid frames and threads. Comes with a microfiber cleaning cloth which can be stored in the case. Recommended.

If you're like me, you like the idea of neutral density filters, but your uses for them are occasional enough that you can't justify spending a whole lot of money on them. It's possible to spend a *lot* on a neutral density filter (which you should do if you're using it all the time or you're a professional). It's also possible to get really cheap neutral density filters, but the quality of those is often variable at best. This set of K&F Concept ND filters sits in a good middle ground -- not overly expensive (especially since you're getting three filters of differing strengths), but still good enough quality that you won't regret using them.

These filters seem overall well constructed. The coatings are even, and they maintain a good, even consistency across the frame. It is possible to stack them to get different strengths. On my mid-range zoom, I have no problems with vignetting.

They come with a fairly nice little case to hold all three. I'm not sure it'll stand up to a whole lot of abuse, but if you're reasonable with your handling of it I think it will be fine.

The reason that I am rating these at four stars rather than five is because their aluminum rings do seem to be a bit prone to binding. I put one on my lens and had a bit of difficulty getting it back off. This isn't an uncommon issue with filters that use aluminum, it's one of the reasons to consider spending the extra money on higher end ones that are made of brass. I think they'll be fine, but I do intend to get a filter wrench and keep it in my camera bag whenever I might be using them, just in case. I don't want to get out into the field and find myself stuck with an ND lens that I can't remove.

These are also very light weight. Surprisingly light weight. I haven't weighed them, but just from feel I think they might be the lightest filters I've ever owned. That's not necessarily a bad thing... If they actually hold up, that's great, in fact. But it does give me a little bit of concern over how well they'll hold up over time though. Since these are occasional use items for me, they'll probably be fine.

Overall, despite some reservations about the binding, I'd recommend these for hobbyists looking for occasional-use ND filters.

Well made quality filters, with excellent optics, and a sturdy metal frame. The bundle comes with an 8, 64, 1000 ND filters and they look and work excellent, they screw on satisfyingly onto your lens and offer clear optics. The case it comes in also is good enough to take on trips or work.

The build quality of the filters is pretty good. The rim has a good grip that helps mount/unmount the filter. I have no issue with threading of the filters to put them onto my lenses. Additionally, these filters allow you to stack them. You can mount a filter on top of another. The coating and surface of the filter are even. From pictures taken with those filters on, I don't see dark strips or uneven light. I don't see much of color casting either. Overall, I would say that these are quality filters. I know some of filter kits nowadays have magnet mount mechanism. There are advantages for that. And this one doesn't have that. It doesn't design to be that way. Just need to be aware of this in your selection.

These ND filters are nice. Lightweight, good grip on the metal ring, decent optics, great case.

There might be a slight bit of extra lens flare type stuff going on but i haven't noticed anything that stands out.

These work perfect on my Sony 18-105. They are a must in sunny weather especially here in super SUNNY south Florida. I can keep my aperture wide open when i need and get those beautiful portraits. If you live in a sunny area these are a must have.... MUST HAVE.

K&F Concept ND filter set 58mm ND8+ND64+ND1000 filter, approx.

As an amateur photographer and especially for astrophotography, I of course have a sturdy tripod so that I can take long-term pictures at night, for example with the mount.
So far, I've lacked strong ND filters for the day.

For relatively little money, K&F offers a slim set of 3 in this segment. The three ND8, 64 and 1000 filters are delivered in a foldable bag. The filters can also be easily screwed onto an existing Skylight, the thread dimensions have been kept clean. The package contains 3 wet cleaning wipes.

I did the test with manual adjustments on my Fujifilm X-E2. Set to F22 and set to 1 second in bulb mode using the Rollei remote trigger. As you can see, the first image without an ND filter is completely outshone. ND8 shows at least an outshining sky, at ND1000 it was the end or, as expected, deep night.
It was only the F10 setting and 30 seconds that an image could be seen again.

Of course, I could now also have shot the sea - if one had been nearby - or a stream in long exposure, but with today's sunny weather, wind turbines are a change of pace, aren't they?
:-)

In oblique light, I could not see any optical errors or inclusions on the filters.

Conclusion: I give 5 stars for the money including the filter bag

I think this is a bargain deal, for what you get. I also think I'm a little spoiled with magnetic stackable filters, to where these aren't quite as exciting for me as they used to be. But I can say that, if I were buying my first filter set, or if I was just used to screwing filters on. Or, I was trying to save money, or simply couldn't afford more expensive filters, I would call these a 5 star experience.
I saw another reviewer mention their being aluminum, and having a tendency to bind more than other materials. I've had that problem in the past, but not with these yet. Just something to keep in mind. Try not to tighten them too hard, and I've never done this, but I imagine it's a thing... I bet you can very lightly lubricate them somehow, being careful not to get it on the lens. Don't quote me on that, and maybe consult your doctor, lawyer, psychiatrist, professional photographer before attempting such a stunt.
Other than that, you are getting what you pay for here. I love K&F, and love the effect of their ND filters for glare and contrast, and a much more cinematic/professional look to your content
