Hello all!This is my first post and I am very excited. I apologize for any errors. I am fairly new to photography and have no formal training. However, I have been asked to photograph some athletic training sessions and have run into a few problems. The facility is not very well lit and the training is at very high speeds. As you can Imagine there is a great deal of blur to combat. Such as the following. Here are the specs Shutter- 1/13 Apt- f 5.0 focal length- 34mm ISO-800 when I tried a faster shutter speed the image would darken anything slower blurred terribly. I would appreciate any input. And I thank you for your time.
