Currently I'm carrying around just one of my 5D Mark III bodies with the 24-105mm L lens attached. A recent used bag purchase give me a nice compact kit which includes my bigger flash, filters, extra batteries and memory cards, remote release, rocket blower etc. I've been keeping an eye out for a used ThinkTank Speed Freak shoulder bag which is the slightly smaller version of a bag I used to own but sold after I stopped using grips on my bodies.
This morning I ventured from the car briefly at the Hudson River and Cohoes Falls in the Mohawk River. The temperature was 11 degrees with a 2 degree wind chill.
These are all hand held five file HDR composites at f/8 and ISO 100.
