How is the quality of the 24-105 on a FF versus a 17-55 on a crop?
I know they are different focal lengths even if adjusting for the crop and I'm not concerned about the 1 stop difference in speed between the two.
If I decide to get the 5d mark III, I'd like to know how the 24-105 compares to my 7d with the 17-55. Getting the 24-70 would be too much money.
