[0.17 lb] Works great with Leica D-Lux 8

[67 mm] This lightweight metal framed filter is well made and functions well. There are other brands of similar filters that cost much more. I have made trial shots with it and I can say that it is a good value and great price.

[67 mm] A filter like this is a MUST HAVE if you want to level up how your images (for photography and video) look in broad, intense daylight in one fell swoop.

They reduce the overall amount of light coming in the camera so you can stop down for a beautiful optically blurred out background and heavily reduce intense sunlight reflections, virtually adding dynamic range in daylight. I knew this would help my shots but my jaw dropped when a got the footage back from testing locations for a project, with and without. (attached photos are screen grabs of video. Shot on Sony A74, Sigma 24-70 f2.8) *Note: This is my first ND filter and first polarizer.

My testing has found a slight cyan cast in the area where sunlight can hit the lens where shadows can be seen, it looks almost dreamy and I kind of like it, but not perfectly color preserving. With Nano-X Pro, I have not encountered any dark X pattern no mater how I adjusted it, which is far better than most Variable ND + Circular Polarizer filters on the market. The included pouch is made of materials that feel great in the hand and its pull tab that makes the filter rise out of the pouch is a very nice touch that makes me wish K&F Concept included this pouch with more filters and also sold separately. I want other filters in these things! (Wile they do sell other pouches. They do not sell the ones included with these filters.)

If you are on the fence and don't have a ND or polarizer, just get it. It took a while for Polar Pro to finally release something like this, and the price of this one STILL undercuts it. If you are a videographer/photographer, image quality is super important and this is a fantastic tool to help you properly expose your shots. There is a reason why Directors of Photography have built in ND filters on their wish list for their cinema cameras and this is why, it makes their job so much easier and allows them to focus on building the look that they want.

[5 x 4.7 x 0.7"] I am a fine atr / abstract photographer. I use this Warm Black Diffusion filter for still life, portrait, landscape and even shots of buildings and vehicles . The color tones of my subjects are very soft...also have an almost ebony hue to them. I seldom use Photoshop...I still love using lense filters. What's not so great? I cannot think of anything right now.

[0.17 lb] I purchased a Nikon 500mm f5.6 and this filter to protect it. This filter does not interfere with the lens hood and the lens cap snaps into it fine. I liked the high light transmissiveness for the price.

[67 mm] Excellent build quality, filter turns super smooth and works great. Such a nice feature having 2 in 1.

[0.17 lb] Took my photos with my 28-70 to the next level, it now lives on that lens and probably will forever. The 1/4 grade is absolutely perfect for everyday use. Will definitely be looking into different sizes for other lenses.

[5 x 4.7 x 0.7"] Great purchase
