I've been getting many queries about choosing bags for travel, for photography gear. The two major domains in which photographers carry their gear on trips are “in-transit,” and during shooting.
In Part I, I discussed the problems of “in-transit” travel, which also affects how you pack for your trip.
In Part II, I discussed the specifications for bags for carrying your gear while “in-transit” which must be considered when choosing bags for that purpose.
In Part III below, I'll discuss bags for carrying your gear while shooting.
The decision when purchasing a bag for carrying photographic gear while “in-transit” is dominated by the stowage options of transit companies, the physical size of their stowage areas, their bag restrictions on the physical size and weight of bags, plus the transit companies' limits on liability.
On the other hand, the decision when purchasing bags for carrying your photographic gear when working or shooting is dominated by bag characteristics which affect their use, protection for your gear, comfort of the photographer, and issues of quality and purpose.
