I am looking for a case which will accommodate a camera body and sigma 100-300 lens with 1.4 teleconverter - about 12.5 inches. Lowepro make a number designed for body and 70-200 but these will be a bit short the Toploader Zoom AW might have done the job butsay it is discontinued. The Thinktank Digital Holster™ 30 should do the job. Does anyone know a shop in Perth (or elsewhere in Australia if necessary) which stocks it or is there an alternative case someone can suggest? I don't need to case to accommodate any other lenses - I have the Lowepro slingshot 200 and Offtrail 2 as alternatives for other lenses.
