I am only posting this because i am bringing my 5d3 and coild bring my 24-70 2.8 ii but have been considering the 24-70 f4l is since i can get one for about $860 and also considering the canon 24-105. For me the thought process was if i can shoot at a lower shutter speed on some of the indoor shots because of the iS then
I could use less flash output for faster recycle times and a lower iso. Also it would be smaller and lighter since some of the trip is a cruise. But when testing it seems that my 24-70 is drastically sharper. Amy i crazy? Has anyone here done a comparision with this? Basucally just trying to see if this lens will help or if I should stay with the 2.8. Ohh the trip is a disney cruise followed by 7 days in the parks.
