Digital Camera World Verdict

Ultraviolet light is typically much less of a problem when shooting with digital cameras, because image sensors are generally less sensitive to UV than photographic film. Even so, strong sunlight can sometimes give rise to haze and errors in color balance, so it’s good news that this filter stops UV in its tracks. Better still, it’s made from super-strong optical glass with no less than 32 layers of nano-structure coatings. It also works brilliantly well for protecting the front element of expensive lenses without degrading in image quality.

Back in the days of photographic film, a UV filter was often seen as essential for blocking ultraviolet light. The Hoya HD nano Mk II UV is arguably much less of a ‘must-have’ accessory for digital cameras and their ranks of multi-coated lenses, but it still has a lot to offer.
