I posted yesterday about a recommendation for a good indoor zoom lens to be used on family portraits and such. He'd prefer not to use flash, but has a 580ex incase he needs it.
He was looking for a mid-level lens, as he was trying not to spend much, but after reading reviews on several recommended lenses from this forum and another, he decided money doesn't matter. I recommended the 24-70mm 2.8L and he would like to get some feedback on the lens, besides from the reviews section.
