So, as the subject says, I'm thinking of getting one of the older 20-35 f/2.8L or 17-35 f/2.8L lenses. Obviously used. My debate is over cost, availability, and the fact that the 5d3 does have a CA removal profile for the 17-35, but not the 20-35. Also I've read that the 20-35 has little to no distortion, while the 17-35 has some complex distortion, especially at 17.
In terms of the CA, I'm guessing LR4.1 can do a good job of that and there's a profile for it already, and also I'm guessing that LR 4.1 can also do a real good job on the 17-35 to correct the distortion. Anyone used these lenses with LR and can comment on the CA/Distortion correction? Even if it's just LR3, if that could fix it good I'm assuming LR4 can.
Otherwise, anyone used either or both? Or have a good glass copy to sell? It looks like on ebay the 17-35 is running about $450-650 or so, while Keh.com has the 20-35 for ~$800, but no copies of the 17-35 right now. B&H and Adorama don't have any used. Anywhere else I should be looking?
