Big general question? I have a 20D and 70-200 IS lens. I shoot sports for my kids?s school. In daylight the sports auto setting works great. For night games and gym (both with marginal HID lighting) I use M and the average exposure is f2.8 1/200 at ISO 1600. Results okay & sometimes good but wish for better sharpness and color rendition. I attribute fuzzy pics as focus issues (the AF not always picking up the correct subject) and depth of field. I just discovered the setting that allows 3200 ISO (H). Does anyone have an array of suggestions that would improve the outcome, such as setting white balance manually (instead of post- production correction), using ISO 3200 and maybe a smaller aperture to allow for more depth of field, and if so what is the slowest practical shutter speed for football and basketball action? Also, how best to set the metering parameters under manual shooting? Do I need to use a control setting other than M? The 20D is an amazing instrument but I am not certain I am taking advantage of all the features under these shooting conditions.
