Originally posted by Clavius I don't care why they are expensive; but the expensive flashy bags that have "CAMERABAG" and "EXPENSIVE GEAR" written all over them are the ones to avoid. Unless you're insured for theft and need a new camera...
I may be the one who suggested using a diaper bag once, but it was for the exact reason you mention. I got the suggestion from someone who was a travel guide...and they got the tip from someone who lived in a particular country where the local thieves were targeting tourists with expensive camera bags. The thieves were coming up from behind, quckly cutting the straps, and taking everything before the tourist knew what hit them. The guide suggested only carrying the gear you thought you'd need for the day and using a diaper bag to carry it in because nobody steals diapers. If the OP is concerned about the high price of good quality camera bags, there are ways around it, as folks have pointed out. You can have the same high priced bag for a fraction of the cost. You just have to pay in patience and legwork, rather than money.
