If you want to travel light then this is the ideal camera bag setup. I show you what’s in my Billingham Hadley Pro bag.
I use the Black Hadley Pro and I like the size of this bag for my Gear. I can easily mix camera equipment such as 50mm 1.4 canon 550d with a 24-70 2.8, A flash and some extra batteries. It is an expensive bag and I have seen cheaper similar bags which you may prefer but I find the billingham stands out as a market leader for its size and convenience.
