Beta Shells are made for those of you planning on taking your DSLR beyond Christmas dinner centrepiece shots - say, a mountain, or in the snow. Each is made from super-tough polymer, sealed against the weather, and padded with foam.
The rundown of the Beta Shell's specs are full of brawniness - steel screws, adhesive-blocked seams, neoprene and visco-elastic impact foam - the point being that you can drop this sucker, have it rained on, and maybe have a wolf take a chomp at it, and the delicate lens inside will stand a decent chance of survival. The cases come in two sizes - for lenses with max external diamaters of 68mm or 87mm.
And here, in case you are sceptical, is a video of a Beta Shell being run over by a truck.
