I can't recommend a specific make because I can't even find one like mine on Ebay to point you in that direction. But I use an Olympus 'branded' backpack that came free when I bought my E3 new, so it is a large DSLR type pack with a fully opening 'lid' when laid flat. But in it I carry almost exactly the equivalent of what you want to carry, only with an M.P.P. technical camera, not the Linhof. There is plenty of space and compartments possible with the dividers commonly included in bags, but without it being a vast size overall which is overkill and makes transport more difficult. So perhaps I can help by giving you the dimensions and you can research more bags from there. The internal dimensions are 34cm wide, 39cm tall, and 14cm deep.
