Has anyone ever tried to use an LLbean Continental Rucksack as a 4x5 field camer a backpack? By the photo in the catalog, it looks as if it might be big enough f or my Wista, lenses, meter and film holders. I'm sure it doesn't have any interi or padding or compartments to keep stuff from banging around, but it seems to me that if I wrap my camera in the dark cloth and keep the lenses in some sort of protective padding, it would be a fine, inexpensive ($55) alternative to the mor e expensive Lowe Pros and F-64s. Thank you for comments.
