K&F been making some serious magic lately with their filters. This is third or fourth from them and this is yet another winner. VNDs are cool, but it's nothing like having an ND to pair with a CPL for photography to get their intended benefits. For this filter in particular, long exposures, especially of rivers and other bodies of water is so easy and so much fun. The filter is quality. Build is beautiful and robust. This is a "buy now, cry now" meaning that it may cost more than others in its category, but you buy it once and it's going to last you the entirety of your career. That's how well this thing is built. It's got some weight to it too and I don't mind that one bit because it all plays into how well it's constructed. This is a great filter that doesn't discolor your images and preserves the quality in detail. Great filter.

..., that's the best way to describe the filter.

I've been taking pictures myself for over 15 years and professionally too. I already had one or the other filter in my hands privately for landscape (polarization filter, ND filter, graduated filter), but I usually didn't spend more than 50-80$ on it. It simply wasn't worth more to me. I was able to request this ND1000 here for testing and I was quite shocked by the price. 200$+ for a 77mm ND filter, I was curious what to expect.

Positive:

- I was already surprised by the packaging. It comes in a kind of cardboard box, which then contains the leather case, a microfiber cloth and the filter. Even then everything looked very high-quality. As for the packaging, I have to say that K&F has come up with something great. In fact, you can convert the packaging into a picture frame. Instructions and material are included. I think that's a great idea. Although only a square photo fits in, I still think it was well thought through.
- The leather case is also of high quality and protects the filter perfectly.
- The filter itself is well made. It is easy to screw into the filter thread, has special spots on the outside edge for more grip and fits perfectly.
- I couldn't find any vignetting during testing because the edge of the filter is very thin.
- I can't fault anything else with the imaging performance, but I couldn't fault anything about my previous cheaper filters either.

Negative:

- The included microfiber cloth could have been saved. Unfortunately, this does not match the high-quality rest. It is so thin that you can look through it.

The filter is not cheap, but it is made of really high quality. I can recommend him.
