If you look through your lens collection buy the size that fits your largest lens filter size. All you have to do after that is buy some step down rings to make it fit any lens smaller than your largest. This should also keep your wide angle lenses from getting cropped by the filter. The filter itself is awesome. Easy to turn from 2-32. Very easy to use.

Easy to use and superb optical quality. I bought a larger size than I needed and a step up ring do I just needed to buy one that would cover up to my largest lens.

I use this for outdoor event videos photos, as well as landscape photos. I do wish I got the one with CPL, but I guess this is better for videography. No issues!

The design is nice and sleek. I like the little box pouch it came in, with this magnet type latch. works as promised and theres no issues so far.

It's a really well built nd filter. I bought it for video and it seems to be working perfect. There is a slight green tone to it but other than that I highly recommend this product

Disappointing in that even at its max setting I can’t take exposures of more than a second or two.

Filter is not wide enough to accommodate even a standard zoom. I have it mounted on a Sony 18-105 f/4 G lens paired with my Sony a6300. In photo mode, all four corners have a very HEAVY vignette. The vignette is visible from 18mm all the way until about 50mm. 18mm isn't even considered wide - angle on an APS-C Camera. The build quality and image quality itself are very good, however, the vignetting renders the filter unusable. Avoid this product if you plan on using it with a lens wider than 50mm.Update: K&F Concepts offered to send a fixed ND 1000 filter plus Step down filters so I am able to use an ND to take photos. I appreciate the help that they offered me so I updated the rating of this product. This 72mm Variable ND filter is very sharp and has no color fringing. If the vignetting issued gets resolved then it would be a near perfect product - especially for the price. Good customer service but subpar product.
