I have not yet used this filter as my new camera has not yet arrived, but the quality looks good and it arrived nicely packaged and very promptly (unlike my camera from Amazon). A close inspection shows it to be a well made precision metal housing with a male and female thread to accommodate the use of additional filters on the front. It has a slim body and should not project more than 4mm from the front of your lens after fitting, the coated glass filter appears to be uniform and blemish free and if up to the usual Hoya standard should be trouble free. I purchased this more as a protector for my lens rather than as a UV filter and will probably leave it fitted most of the time, with that in mind I did not want to fit a really cheap and unknown brand of filter that may degrade the image quality of my new lens, but neither did I want to pay an arm and a leg for one either, so this looks like a good compromise. After being able to test it out in the field I will report back if I find anything detrimental with using this product, so for now I give it 5*.
