NEEWER 77mm Variable ND Filter ND2-ND400 (1-9 Stops), Neutral Density Filter, Multiple Coatings, Water and Scratch Resistant

Works like it should for sunny days. Need to adjust settings on your camera though

ND filters are great for motion blur and reproducing more accurate reproductions and adding streaking effects of moving objects.

Living in a snowy area, ND filters really help me manage light in my photos. Especially on a sunny day or pointing at a light source. I've experienced some challenges with this product but have also achieved some pretty good images using it. I've attached some overexposed images to better show an 'X' anomaly I had with a 120° lense at 8-9 stops. I've also attached some better images at 3 to 5 stops. Seems this 'X' issue is common with variable ND filters. Also, I've experienced and exceptional level of customer service regarding this and the folks representing this product have really come through to help me work through this issue. I started at a 1* review but have revised to a 4* because of this and now have a better understanding of variable ND filters and that this 'X' is just unavoidable under certain conditions.

Pros: works as advertised. The sliding design that allowing for gradual shifts from almost no light filtering to nearly all light filtering is amazing. Seems to be very nice quality and arrived with what appears to be a well-made protective case. The cost seems very reasonable for what I received.Cons: I would actually appreciate if the turning (for filtering adjustment) was just a touch 'stiffer' or had a way to lock it into a specific place (I know I'm asking a lot here for such a little filter). I found it was relatively easy to bump it and end up with more light entering than I expected. This was a very minor issue that certainly could be (and is now) dealt with by exercising more caution.Would absolutely buy again. Bought for the 2024 eclipse in North America and the lens filter performed beautifully.

6/29/2023 Issue resolved by Neewer customer service.I purchased 2 sizes of nd filters for my new Canon RF lenses. The nd filters case cross' on the images and ruin the images completely. I got them specially for our trip to Germany since we would be in the country side and wanted to do landscape photography. At lower nd settings at first it seems ok. But once you get to 7-9 for longer exposures, it does not work properly.

Not bad I’ll use this brand more now

This is an awesome accessory for capturing well exposed sgots when your scene is over exposed due to harsh lighting

Works great as advertised. I use it for photography. Images are still sharp and I like that I can dial in the density as I need it. I use outdoor flash photography.

Buen producto, embalaje y cumple su propósito

quality ok, works ok, for this price, no more extra requirements.

Excellent in the sun

Non riduce di 8 stop come mi aspettavo, ma la cosa peggiore che ha degli aloni incredibili che non ne permettono l'utilizzo in nessuna condizione

Perfecto para mi
