Well, actually a fly reel case, but it holds my Fuji 240, 300 and 450 on 4x4 boards perfectly. The case is padded and has 3 movable dividers in it. All for the sum of $19.99. I know this concept is not new, but I thought I would pass it along for anyone looking for a good lens case to fit in a backpack. It is a White River Reel Case, and measures 4x5x10 inches (model # WR-510FRC). I got mine at Bass Pro Shops, but It may be available elsewhere.
