Hello folks, I am not sure if this is the correct section of the forum to ask this, but anyway.. I have an older Tamrac expedition backpack which is good for organizing my camera gear but the back-system is truly awful. I've been thinking, whether there is any option to buy some sort of "inner case" with dividers to be used in front-loading mid-size (around 30-40litres) hiking backpack - I find those much easier to carry around. After some ebay-searching I have found countless inserts for shoulderbags/messenger style bags but nothing really to fit a regular backpack. (As for the gear - I need to carry a Bronica SQ with an additional lens or two, sometimes a rolleicord as well, and the usual paraphernalia - meter, few filters, spare film...) Thanks for any ideas! A.
