I am looking for buying a good 77mm UV Filter (or UV Haze-1) for my Canon lens. If you have one please respond with complete specs, brand name and details.
A UV can't improve a digital image. It adds an air gap and extra glass promoting flare and the possibility of diminished contrast, depending on the quality of the filter.
If it's lens protection you're after just keep the lens cap on till you're ready to use the lens, and then use the lens hood. A lens hood improves contrast and minimizes lens flare.
