Just got a canon XSI, here are some of my first pics. "Midwest SKY".:thumbup::thumbdown: I have one more question if some one can help me. I got a 8gb sandisk extreme 3, do you think its not necessary for a canon XSI. Because I can still return it and get an Ultra 2 for way less. Best buy has 8 gb ultra 2 for 25$. I do plan to shoot sports and car at a track so I might want to take 10-15 pic in a row, say as a car goes around a corner. Anyone ??? Thanks for the help. 1. 2. deleted 3. 4.
