C640 fits a "large body" with "large lens" attached as defined on this page.
The only holster case available today that holds a full-size DSLR body (including Nikon D1 or D2-series body or Canon 1D-series) and a 70-200/2.8, 80-200/2.8 (snug fit with the AF-S Nikkor IF-ED VR [Silent-Wave] -- no space in the flap pocket), 35-350/3.5, 100-400/4-5.6 lens with the hood in the shooting position.
Also accomodates a body with a Sigma 120-300/2.8 lens with the hood reversed.
Field report (June 07): "I got the bag, C640, very nice, it fit my Canon Mark3 + 400mm 5.6 + 1.4xtc perfectly."
When used on a waistbelt, the optional Y302 strap kit is recommended to prevent the top of the case from pulling away from the belt.
Because of its height, shorter or smaller people may find this LONG case awkward mounted on a belt.
