Note that all watertight cases, except for clear cases, have foam padding
that is not included as part of the internal dimensions. Two layers of foam
padding compressed will reduce the inside measurement by 1/8" (0.125").

Please verify your equipment dimensions as many manufacturers provide
approximate measurements. We've experienced a number of actual
camera measurements to be off from 1/4" to 7/8".
