Daniel thank you for your reply, sorry for getting back to you so much later. Since then I have been taking more indoor photos and want to ask your opinion on a different approach then my first questions.


I have read some other responses on lens versus bodies and iso and aperture and how each one effects the end results. I need some more help with understanding what are the best choices for my needs.


Would I achieve better results with my current 70-200 4L and a new 5DII for basketball/track and portraits or my current 50D and a new 70-2002.8L? I keep reading that the 50D is not the best at higher iso like 1,600 compared to the 5DII. And without using a flash it seems like I have needed to up the iso to at least 1,600 to get a decent sutter speed. So now I am wondering if it wouldn't be better to go with a new body for iso performance rather then 2.8 aperature lenses for right now. Another factor is shutter speed, is the 5DII fast enough for basketball and track pictures?


I would still want to purchase some additional leness as I see my needs develop with a full frame perspective.
