was thinking about buying a 24-70 for a while now, but really didn't want to put down 1100 bucks. was looking at used ones for around 950 or so, but that wasnt a huge amount of savings. was seriously debating on buying a tamron 28-75 again but the loud slow focus and the moving focus ring made me think twice. couple days ago, friend with the 28-70 said he was selling his for 500. 95% of the quality at 50% of the cost. had to have it. cant wait till it gets here.
