Most people who own the 24-70 don't have the 24-105. Others who bought the 24-105 or who sold their 24-70 to buy the 24-105 will tell you the new lens is fantastic. I think the answer is obvious without reading any report. If you need 2.8, buy the 24-70. If one stop doesn't mean much to you, buy the new 24-105 with all the plus such as lighter, extra 71-105, and IS. You won't find your answer until you try them yourself.
