£33 at time of review I'm using it on a Sony A7C and a Sony FE 20 1.8 G lens so if there's any issues that combination would reveal them. I took a series of test shots without the ND, with the ND fully open, and with it stopped down too maximum, both with auto and manual white balance. I shot away from, towards and perpendicular to the sun to check for flaring and glare. With the filter I didn't notice any additional flare than without. Colour rendition was good too, I didn't see any sizeable shift in colour (yes there was slight bit, but you will always get that no matter the manufacturer, it's physics!). I shoot a lot of video, so use variable ND's for that, although I always use variable ND's from the same manufacturer on multi camera shoots as there is always a slight colour shift (usually more noticeable when stoped down), and having now used this I'm happy to say it worked very well. I've several Tiffen ND's and they cost at least twice what this costs and frankly I don't see any issues at all with these (in fact one of my Tiffen's has awful colour shift that I can only use it with stills not video). Hope my review was helpful

I ordered this for my iPhone 15 Pro Max as I do spend an inordinate amount of time these days favoring it over my regular cameras. It threaded nicely into the phone adapter and changing stops was smooth and easy, image results are what I would expect from a filter produced by this company, no weird artifacts ,vignetting or the dreaded X. This is an excellent, premium filter!
