After purchasing my Sigma 10-20mm f4-5.6 EX DC HSM Canon lens which has a 77mm filter size, I wanted to protect my kit with a UV filter so that the lens itself was always protected. I was not after anything overly expensive and after searching around the Internet I came across the Hama UV Filter UV-390 (O-Haze) Ultra Wide 3 mm, 77 mm. At £7.29 from Amazon.co.uk you really can't go wrong with this purchase at all. Most other 77mm uv filters around that I was looking at because of the 77mm size they were after prices from £20 through to £80. And while I liked the look of the £20 models I just could'nt see the difference in those and the Hama equivalent at £7.29. So I took the plunge and bought it. Product arrived well packaged and screwed onto my lens really easily. The glass itself looks decent quality and so far after about a good couple of years use I havent had any issues with it. Don't get me wrong as far as UV filters are concerned this is a budget glass filter. The far more expensive models are better but I just didnt see the point as these do the job just as well. The filter itself is an Ultra-violet light filter which means it helps to block unwanted UV glare from entering your lens itself and thus helps to give better photographic results as well as some lens protection in case you bump it. It is colour neutral as well so you can't tell that there is a filter on the end of your camera lens unless you really look. Overall i'm happy with the purchase and i'd recommend it to anyone.
