Yes, the best camera is the one which is available/in your hands.
I am going to visit Rome in February. Was there before two times.
With my 5dIII. Some lenses. One flash.
And my Sony RX100.
I want to make some big prints from the pictures I take there.
Therefore: nice pictures, but I am sacrifying some of my human power to carry my backpack.
(Comfortable ThinkTank Streetwalker HD, can only recommend it).
I love Italy!!
