I purchased a Digital Holster 40 for my D-80 / MB-D80 / 70-200 f2.8 VR lens rig - its great! I no longer worry about supporting the camera / heavy lens combination by the camera strap - I stick it in the case instead. I also like the ability to have two different case depths - so when I have the 18-135 mounted, I can reduce the case length. I was originally pining for a Lowepro Toploader 75 AW before I discovered this case and have never looked back.
