No need to apologize, because I have to thank you for this misunderstood abbreviation!Wow. Sorry about that. Was talking about the Think Tank Digital Holster. Need to be more careful with my abbreviations
By "accident", I've found what is for me the perfect solution for carrying a DSLR plus EF 100-400! Give the Tasmanian Tiger camera holster a look, it's made by the well-known outdoor-company Tatonka. Its advantage is that one simply slides the camera -lens first- in or out, without the need for any other manipulation. The tele-zoom is ready within seconds.
