I have a Canon 20d and I have been shooting with it for about a year now. I used a EF 75-300 lens for my sports shots but I was not getting a very good quality for my indoor sports such as basketball. So I asked some people about the 24-70 and they raved about how it will work great for indoors becouse of the way it lets the light in ect.... Well the problem is I used it one time for basketball and got really good shots, but the last two times I have used it not even for just basketball but for a school function "grandparents day" at my kids school, my pictures are blurry and it really makes me sick. I don't know what I am doing that is so different now or if I have just got myself it a distressed mood so I just can't figure it out, or if it is the lens.
People expect these pictures to be taken of their kids so they can buy them and the I am not getting anything to offer them and I am wasting my time. If you have any thoughts on what I can do or what I should be doing I would really appreciate it.
thanks
