When buying a new bag, I wasn't sure whether the 5d would fit into the Crumpler 4 million dollar home bag. It does, but there is not much room to spare.
Canon 24-70 L lens is attached to the camera w/hood reversed; Canon 85mm f1.8 lens is in the pocket to the right of the camera. The strap tucks neatly into the space to the right of the camera.
The 5d will NOT fit with the 550EX lens next to it, nor will it fit with the 70-200 2.8 or 4 L lens attached. No way.
The fit is a bit snug front-to-back, but there is still room in the front velcro pocket for spare batteries, CF cards, filters or other small items.
Also, if I take this setup out and decide to use the 85mm lens, I cannot put the camera into the bag that way--the body will not fit into the bag with the 24-70 in the side pocket.
