The question of whether or not to use a UV filter often come up on the forum. The usual comments are use it for protection of the front element or don't use it as it reduces image quality. I have never seen a demonstration of the quality loss argument so I decided to see for myself. I took two shots in bright sunlight, one with a UV filter & one without. That is the only difference between the two shots. 1. With UV filter 2. WithOUT UV filter In this demonstration it is clear the image quality is diminished by the UV filter. Damn, just did a preview & see that by using Photobucket to host the images they look much alike here on the forum. What a piss-off. I assure you there is a significant difference in the originals.
