Just a follow up to a post of mine made a few days ago. I was looking for a zoom lens for my 30D and my budget was $400.00 at the time. Now after reading suggestions from a few of you I did buy the Canon EF 70-200mm f/4 non IS. This will be used for shooting my son's ball games during the day. I would have gotten the 2.8 version but just couldn't justify the extra money. So I ordered the lens yesterday from Cameta camera in NY and I should have it by Monday or Tuesday. Thank you to all who guided me in the right direction.
