I generally shoot at f4, and at f4 the f2.8 is better than the 24-105L wide open. If you need less DOF, then 24-70mm at f2.8. If you shoot at f4, 24-70mm better resolution, but if slow speed, the 24-105mm IS can make the difference (resolution vs. shaking).

It looks like Canon has gone backwards on they line of L lens with this one. This lens does offer some + points like light weight and 0.7X macro feature.dNrLS.
