Firstly, I appologise if this has been asked before. I did a search for 'rucksack' but didn't come across the answers I require.
I have a Sinar F2 (Fairly large but I usually fold the standards down flat) with several lenses, and all the usual extras, kept in a few plastic 'lunchbox' tubs. I currently carry it in an old hiking rucksack which is fine, though entry in the top is prohibitively tight. I need to find something else, with large capacity for all this and perhaps my digital SLR aswell, for metering/record shots etc... Ideally, a rucksack shoulder system for comfortable walking reasonably long distances but most importantly, with some sort of full front opening, for ease of access. It doesn't have to be a proper 'photo' rucksack. It just has to be big enough, comfortable and easily accessible.
Any ideas? Thanks for your time.
