K&F Concept 100x100mm Square ND Filter Kit ND1000 (10 Stop) + 1x Filter Holder + 8 x Filter Rings with 28 Multi-Layer Coatings Compatible with Canon Nikon Camera Lens

A few years ago, I started beefing up my camera equipment. I had a Canon 5D Mark IV camera body, but didn’t have great glass. So, I started my gear journey by upgrading my lenses. I now have four amazing lenses including a 70-200, 24-70, 100mm Macro, and a Wide Angle lens. After I finalized my collection of lenses, I started looking at accessories I needed to accompany those lenses and came up with a short list of items that included high-quality filters. The problem I had was that I needed to be able have filters that works with all my lenses. Buying filters for each one of your lenses can get really cost prohibitive. So, one solution I found was to get a square filter with step-down rings. K&F Concept has a great option for this type of set-up so I gave it a try.About a month ago, I shot photos at a wedding on a mountaintop in Tennessee. It was in the middle of the afternoon and the sun was super bright at the location of the ceremony. The venue was huge and I wanted to pack my camera bag somewhat light so that I didn’t have to struggle with tons of equipment. The square filter set from K&F concept was perfect for this type of work. The kit is lightweight and it makes it possible to use the one filter for several different sizes of lenses. During this wedding I was working with an 82mm lens and a 77mm lens as my primary glass. At the ceremony site, I had to quickly swap lenses and reapply the filter in order to get the shots the couple wanted. I found gaps in the ceremony where I could quietly and quickly change lenses and attach the filters without disturbing the event. It worked perfectly and even though some people might consider it cumbersome, I thought it was a lot easier than having to swap lenses and then screw filter into each lens.When using these filters, I shot exclusively in RAW, but did not perceive any color cast from the filters. The mount is solid and the filter is well-protected by the soft lining in the case. It’s very easy to attach the mount to the lenses and in my opinion is actually easier to work with than individual filters.I do feel like the lens adapter could fit a little more snuggly onto the camera lens, but I’m definitely not complaining about that and it is certainly not a dealbreaker. It’s just a tweak that could make the product even better than it already is.One of the most appealing features of this product is its price. At $73, it’s much more budget-friendly than purchasing a single ND1000 filter. This is a great set-up for beginners and professionals alike.

Used these in Yellowstone last month in the snow. Sturdy, fits well and holds glass securely. Optically clear, no distortion. But dont drop them, they are glass...

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!

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?

I think this kit is awesome, I ordered it to use with my EOS Rebel T7. With the gradient filter, I have a much better control to reduce the exposure or my sky on landscape pictures. My landscape pictures are now MUCH nicer.I also ordered the K&B Hard filter 3 steps along with this kit containing the Soft filter 3 steps. Both filters are equally useful and pretty nice quality in my opinion. With the included holder, I can stack both filters to get an even darker sky, especially facing sunlight, super cool.That way I can take my picture with exposure well adjusted on the sky and it makes things MUCH easier to adjust the darker parts of my images in Darktable.

good

The lens adapter fits well but the holder is loosely clamped onto the lens adapter such that the holder could rotate too easily. The GND filter require a lot of push into the holder to the point that I am afraid of breaking the glass. Overall good value for an introductory product.

高価な物が多い角形フィルターですが、とても安価で買いやすい商品です。しかし、色がニュートラルとは言えず、ホワイトバランスを調整してもなんだか微妙に色がおかしい。

100x100ガラス板、1000NDは三脚、レリーズシャッターになるが、異形レンズ枠が同梱されており、現場でもまごつかずに設置出来る。日中利用したが、流雲、風に揺れる木々等それなりに撮れるが、まだ真髄に触れる迄には行かない。400NDをかさねるともっと効果が出るかと思われる。一度実用講座を受けて居たのでまごつかなかったが、説明文のみでは難しいと思う。円形のND8をレンズに直接装着すると手軽に利用できる。ND1000、400の円形フィルターがあるのか疑問。
