I have been seriously taking pictures of my boys playing baseball the past two years. I have been using the sports icon on the camera dial and using a 50-200mm1:4-5.6G ed Nikon DX lens. I have in the past few weeks been using the shutter speed on the dial and playing with the shutter speed and the aperture, not being very successful. The LED screen keeps telling me that the subject is too dark, yet when I take the picture it doesn't appear to be and looks in focus. Once I take the pictures and put them on the computer they are dark and out of focus. Also, I find that when I am adjusting the settings that sometimes when I push the button to take the photo nothing happens. It is almost like the camera has not caught up with my new settings. Most of the time I am taking photos at around 3-9 p.m. Here's what I want to know. Can you suggest the settings for ISO, shutter speed and aperture while shooting between lets say 2 p.m. to dusk? Then suggestions for after dusk under the stadium lights? I am looking into buying a 70-300mm lens or 55-300mm lens, what do you suggest? Don't get me wrong, I do have some good photos but I have missed some really great shots because I wasn't in focus, and they were washed out.
