Originally posted by Driline Man that zoom is Gargantuan compared to the DA*200 and more than twice as heavy! So how's the IQ compare at 200mm between the two?
Well, the obvious thing is that the 70-200 covers more focal lengths. The 70-200 has better border sharpness on full frame wide open, is a faster focusing lens, and has less purple fringing. By f4, I would have a hard time telling them apart.
My wife shoots weddings and she felt that the difference in auto focus was significant enough that she is willing to deal with the size difference and there's no reason to have both. As a pure walk around lens, size-wise, I would much prefer the DA *200.
