Camera Lens UV Filter Test: Does coating make a difference?

I decided to do a quick test to see how my collection of 58mm UV filters damage image quality. I also took an image without a filter to see what difference using no filter makes.  A simple test. Why do I personally use filters? I want the added protection that a filter brings as well as the simplicity of cleaning a filter instead of the front element of the lens. I occasionally take the filter off when I know the situation will cause issues such as extreme reflections from that added glass. This test was intended to test reflection and glare, not image sharpness. I might eventually do another test to see if there is a reduction in sharpness. Here is an image with all filters and the no filter sample. Here is the video I put together as I was testing: http://www.youtube.com/watch?v=V-ituue1zeo Get the replacement Hoya 58mm EVO Antistatic UV(0) Filter here: B&H Photo Video Amazon.com Used from KEH.com Get the Hoya 58mm Ultraviolet UV(0) Super Multi-Coated (S-HMC) Glass Haze Filter he
