i think im gonna go with the 24-105 f/4 for the general purpose for now. i do alot of traveling and need it more i think for that purpose. the wife hates if im swaping lens all day long while doing museums and out door stuff like the pyramids and such. it was perfect while walking in amsterdam last week.
so i guess ill get a cheap fixed prime or cheap ultra wide and take the hit on lesser glass for those lenses as ill be doing out door high light shots of cars.
