Football Action

This morning my nephew had a football game and I was able to get some shots with my D-50. Last week I noticed that my 1A skylight filter produced a very noticable haze on the image when I was pointing toward the sun. My other lens had a 1B filter and it appeared fine. So today I made sure I had my back to the sun. From what I've read about skylight filters, I wasn't aware there was really much difference but I guess there is.
