49mm ND8+ND64+ND1000 Lens Filter Kit with 3 Vacuum Cleaning Cloths and Filter Pouch, 24 Layer Multi-coated HD Optical Glass, Nano-Dazzle Series

Allow long exposures without brightening the photo.

I expected delivery to be better packaged.
The original package was slightly crushed, but luckily everything was good inside. The filters look good, even with the bag.
I tried out the first pictures right away and I can't complain. Nothing that bothers me. You just have to be careful not to screw on the filters too hard, otherwise it will be difficult to get rid of them. It was like that the first time and then it wasn't a problem anymore.

Just like prime lenses, ND filters work much in the same way. Generally you get better quality as opposed to a variable ND. This set gives you 3 ranges that are useful for shooting outdoors (3, 6 and 10). These filters will work great for both video and photo. They will help you with longer exposures (ie: waterfalls) as well as a shallower depth of field (ie: f2.8). Good set of filters.

Very good filters. Great value for money!

This kit includes three separate filters, ND8, ND64, and ND1000, covering the most recommended ranges of 3, 6, and 10 stops of light reduction. These three are versatile for a wide range of scenarios. The description erroneously describes them as 3/4/10, but the product images state it correctly. The filters have easy to engage threads, they feel solid, and they come in a great carrying case to protect them when not in use or in a camera bag. In my testing, the images with them look great with minimal impact on sharpness and the light reduction is even. As with nearly all ND filters, color casts are there, but it's correctable if using manual white balance and auto white balance takes care of it in other cases.

Since I've mainly photographed with variable ND filters so far, I wanted to buy a set with fixed values to have even more leeway. The filters have different dimming levels:

ND8 - corresponds to 3 f-stops
ND64 - corresponds to 6 f-stops
ND1000 - corresponds to 10 f-stops

To calculate the shutter speed, you simply have to multiply the time by the ND number, for example if you have a shutter speed of 1/1000s and want to use an ND64 filter, you get a time of 1/15s.

An example:
1/1000 = 0.001 * 64 = 0.064s
For times less than 1s, you then have to take the reciprocal, i.e.:
1/0.064 = 15.624 i.e. a new shutter speed of around 1/15s

You can calculate this with the calculator, or you can use one of the many apps that calculate the whole thing very easily on your smartphone, you just have to enter the values. Alternatively, you can try things out a bit and after a while you have enough experience that you can roughly estimate it without calculating. Alternatively, you can also find tables on the Internet that you can print out and take with you.

But enough about the theory now. The filters make a very valuable impression. Of course, you can also buy such filters in completely different price ranges and that may be fine for a professional photographer who earns his money with them, but for the normal photographer who does this as a hobby or simply does not shoot in the high-end sector, these filters are great.

They are very flat, which has the advantage that you don't see a vignette in the corners with wide-angle lenses. You can even combine the filters to achieve even longer shutter speeds. Yes, you could combine them even with a variable filter. As a rule, with these 3 filters alone, you can set the correct shutter speed for pretty much all common situations. You can still compensate a bit with aperture and ISO. When combining, you just have to make sure that the filters then apply something to the front of the lens and then you may have to expect vignetting at the ultra wide angle. I tested the filters with my Tamron 28-75m f2.8 and I had no problems with that.

The image quality is very good, especially considering the price. Getting 3 filters for just under 50 euros (at the time of writing this review) is a very good offer. What's more, you get the case in which you can safely transport the 3.

There, the filters are simply pushed into the respective pocket. When taking it out, you just have to be careful not to reach into the glass, otherwise you will have fingerprints on the glass. But with a little mindfulness, this can be avoided.

For me, this is a great set that also gets 5 stars. Of course, I can also recommend a purchase. A good solution for beginners and advanced photographers. Professional photographers usually have their preferred brand and filter models anyway.

I am happy with this set. I like how I can play with longer exposures in brighter conditions. I did not see any artifacts or distortions from the filters so they seem to be made well. They fit my lens well and the case is a nice touch, though bulky.

I'd heard of K&F concept before and first tried one of their circular polarizers. I went out and shot some sample photos with it to compare with my expensive filters, which I apparently cannot name, because my review of the C-PL in which I named them was rejected. Let me say here that the K&F C-PL impressed me. I thought the shots with my other polarizers that cost four and five times more than the K&F were the K&F shots, because they weren't as good. But I was wrong; the K&F shots were the best.

I didn't take these NDs out for comparison, but I did use them to shoot the recent annular eclipse. I got some great shots using the ten-stop filter. No glare, no flare. Since I was bracketing my exposures, and since I had plenty of time, I tried stacking two NDs, the 1000 with the 64, and got a fair amount of flare. I'm not surprised, and I don't hold it against the filters. I know better than to stack them and I'd never do that in any other situation.

With either the ND1000 or the ND64 mounted I had no flare. I bracketed exposure to get a decent foreground in some shots and a decent crescent sun on others to later combine in post processing. When I bumped up the exposure for the foreground, the sharpness and color were perfect -- you'd never know there was an ND filter in front of the lens. I expected there to be at least a slight color cast, but there was none. A cast wouldn't bother me, as I shoot RAW and process my own photos anyway, and this is exceedingly easy to correct. The cost of an ND, right? Nope. Not with these.

I wholeheartedly and without reservation recommend these K&F ND filters. While I'm at it, I even more strongly recommend the K&F Nano-X series C-PL, a circular polarizer that outperforms my others that cost 4-5 times more.

I've said it before and I'll say it again. but K&F Concept is one of my favorite bargain photography brands. They make good quality things and don't charge an arm and a leg for them. I love photography, but I am not the type of person to pixel-peep and I don't need the absolute best image quality for paid photo shoots. I take pictures as a hobby and these filters are great for that. Are they as good as other more expensive brands? I have no idea, but I do know that for about $50 this is a great set of ND filters that will help you take better pictures in certain conditions. Research ND filter photography and then buy these if you have an interest in how they can help you.

These ND filters are well made and thread securely onto the lens. The set of three provides many options for creative photography. I did a quick trial run with a sunset and turning a rough sea into a smooth one.

They come in a very convenient carry case to keep them safe when not in use.

If you haven't used ND filters, just google for ideas, and be very specific about which size you buy to fit your lens. If you have used ND filters before, then you'll be happy with this set.

I can't wait to put these to use in various ways.
