Review: Good filter good quality . - This is a decent uv filter it fits on the threads very smoothly with little effort, works well as a uv and protective shield of the camera lens. Easy to fit nice and compact to. It doesn’t distort the colour of photos and gives a slight vignette and feels well made and durable. I have found it’s giving more camera flares though that’s the only downside but I can deal with that in post editing. I’d buy again and it’s a great price too for a good quality filter.
Review: Constructed using Japanese Asahi glass, it offers quality at a value price - UV filters are a great fit-and-forget way to protect expensive lenses from scratches. This one is well made, fairly priced, and even comes in some of the most stylish packaging I’ve seen in a long time. A thoughtful extra is the vacuum-packed microfibre cleaning cloth — a genuinely useful addition to any camera bag. Made in China using Japanese Asahi glass, it offers quality at a value price. The slim profile and solid barrel grip make it easy to handle, and it protects my Canon lens with no noticeable loss in image quality. Fit and finish are excellent.

## Features

- High Quality: Built with Japan Optics glass for top level light transmittance, increasing optical clarity and colour fidelity. Multiple coated filter allows 99% transmittance compared to 90% transmittance of normal UV filters on the market.

Nice fit, was a bit concerned at first as unable to take off but there's a knack. Hasn't effected the quality of photos. Happy with purchase.
