After spending some time wandering around European capitals with the 5D or 5DII with the 17-40 f4L and 70-200f4L IS, I concluded it's a mug's game (for me anyway) to travel loaded down with so much (heavy) kit. Now I just travel with the 6D and 24-105 f4L IS and the combo worked just fine tor travelling to OZ (Melbourne and Sydney) via Japan (Tokyo) for a month earlier this year.The 24-105 is a wonderful one-stop travel lens of excellent quality though wrongly maligned in some quarters. It has wonderful colour and contrast and the IS is excellent. That would be my choice for the 5D. Enjoy your travels!
