I love this ND. It has no surprise artifacts and didn't melt my wallet.Arrived promptly and in good condition.I would recommend going with the biggest size you can use and use step rings unless you share gear.

I just bought the Sigma 16mm 1.4 however I wasn't able to take full advantage of lower fstop at 1.4, and I came across this 67mm ND filter on Amazon, and I can honestly say that this is exactly what I was looking for. it allowed me to get that smooth bokeh in bright sunlight. and this was the reason why I bought this lens. So if you own a Sigma 16mm 1.4 this is a must have ND filter, it fits perfectly on the lens and has an adjustable ring. Also, I loved the packaging! it comes with a case for the nd filter when you are not using it.

Build quality is superb for the price! Fits well on my Tamron 28-75mm Sony E-mount lens. I haven't had any major issues with photos as long as you stay within the min and max ranges. Definitely a great buy!!

I had a smaller diameter of this product for a different lens, so when I got my new lens the first thing I bought was this ND filter. It is incredible. And this one had little dots along the edge, as well as text that read "Min" and "Max". This was super helpful. My only complaint about the smaller ones was that you couldn't tell how far was the maximum and minimum, and this model has solved that issue. I don't go anywhere without this filter. I will be buying a K&F Variable ND filter for every lens that I get from now on.

I was reading reviews for other ND filters and found this one for the price to work great for what i will be doing. The build quality is really nice, it has some weight to it so it feels strong, the glass is really clean and it works perfect, I got this for my 35mm 1.8 and it allows me to take pictures and shoot video in full daylight at a wide aperture of 1.8 with an even balance of blue in the sky to the greens in the grass. I was really impressed with the quality of this filter. I will be getting another one for my 50mm 1.8. I'm using it for mid day long exposures of waterfalls and cloud landscapes. Also this helps give a cinematic look for shooting video which looks really nice! I didn't see any noticeable loss of detail in images or video which is what i was worried about. I did NOT notice any kind of X or shadowing from this filter. It is probably from using a wide angle lens. I highly recommend this ND filter!

This thing is ridiculous! Got it yesterday and took it out today for some waterfall pics in a small stream close by. This was around 5 in the afternoon. Nice, bright, sunny day. I was able to get 20 second shots with no problem and could have taken even longer ones. I did get a few nasty flares on a few of my pics but I think that was my bad as I was shooting towards the sun and it is not on all of my pictures. I'll have to try again and shoot with the sun to my back and see how it does. But for the price there is no reason not to have one for each of your lenses. Very happy with this. And it's nicely constructed of metal and screw in smoothly. 6 Stars!
