I own a Canon 40D with a 70-200 Canon EF lens (white, professional series). A friend asked me to take some action shots of her son's peewee football game yesterday. The game was 12:30 in the afternoon, and the day was mostly overcast, some breaks of sun, and a bit windy. I've never photographed football before. Most of my sports shots are of my children's summer outdoor swim meets.
I shot the game using the 70-200 lens. I used the Tv mode and had the shutter speed set to 1000 or 1600 with an iso of 400. Many of the shots were blurry. Some seemed as if the autofocus couldn't figure out what to grab, because the trees behind the action were in focus, but the players were not. Others, the entire photo was blurry. I did hit some nice shots, but I deleted a whole lot of fuzzy shots as well.
I have noticed that even with the swimming shots, which I can usually get some sharp images of, were fuzzier this summer (I deleted more than usual). I did play around with the settings during swim season; I was feeling more secure with the camera and lens I guess. I am wondering if I messed with a setting and didn't realize I did, and now it is impacting other situations. I am getting frustrated because even though the image appears to be good on the screen on the back of the camera, when I get home and get it up on the computer screen, I see the fuzziness and want to scream.
Any help or suggestions would be greatly appreciated. Thanks!
