Do you use 5D III plus 24-105 as travel camera?

And I thank his complimenton my photos 

Agreed.  Even with 24-70L/2.8 II and Tamron 24-70/2.8 VC into consideration, 24-105L arguably is still the best overall choice and compromise if you only carry one lens in travelling.  It has extra 35mm tele range, it has 'IS' that is very effective (I usually don't quite trust third party VC or OS) and it has excellent colors and sharpness (at least at 2/3 of center and mid areas that I care most).  Having said that, I will get 24-70L II and understand I do need 70-200L/4.0 IS to complement each other.  A bit of inconvenience and heavier, but I can use f/2.8 if necessary that still sharp even at edges, less distortion at 24mm, better bokeh in portraiture and slightly better micro contrast.  Only individuals can decide if worth 2-3X price more than its competitors.
