Camera Backpack

[BillW]

Morning Brant;
Glad to see you've reached the saturation point. It's quite the rabbit hole, researching for a new equipment backpack.
I went through this same dilemma a couple of years ago. I finally stepped away and simply wrote down what I wanted/needed in a day backpack. ICU was a high priority.
I didn't have as many choices as there are today, so it was a bit simpler. I purchased the F-Stop Ajna 40L with the Essential ICU. It carries all my wildlife/landscape equipment safely; 2 bodies (1DXMKII & 5DMKIII), 3 lenses (100-400, 70-200, 24-105) and if I need a 4th lens (e.g. 16-35 2.8) there is sufficient room.
There is still sufficient room for additional needs; H2O, snacks, etc.
Also I find it quite comfortable.
Good luck Brant.
Regards
Bill
