Hello;
I asked a floor manager in our store to test a few options:
The black ACPRO650 Standard DSLR Holster from Ape Case is a compact, affordable way to tote around your DSLR with a lens up to 6.5" (16.5 cm). The water-resistant nylon exterior covers a padded Hi-Vis Yellow interior that makes seeing inside the holster easier in marginal light.
The black Digital Holster 20 V2.0 from Think Tank contains a unique "Pop Down" feature that allows the lens hood to be kept on the camera held in shooting position. For the active shooter, this is a real time-saver. The case is made to hold a regular-sized DSLR such as a Canon 5D Mark II, 7D or Nikon D700 with a standard zoom attached or when the "Pop Down" feature is employed, it can accommodate a DSLR with a 70-200mm f/2.8 with hood reversed.
