OM System LSC-1127 Lens Case for 300mm F4.0 PRO and 100-400mm IS II

This is the largest of the drawstring lens cases, cut for the M.Zuiko Digital ED 300mm F4.0 IS PRO and the ED 100-400mm F5.0-6.3 IS II. Both are long, heavy and expensive enough that loose transport is a genuine risk rather than a fussy concern.

Padded through the wall and the base, with a rugged outer and a drawstring top. Being custom-fitted matters most on a lens this length, because a case with slack lets the weight swing and load the mount end on every step.
