So I've run into my first problem reviewing camera bags, I have to use my camera to photograph things so it can't be in the bag as I photograph it! So I've left space in this photo where my Canon 6D would reside with a lens attached. I decided to snap an Iphone photo of my real camera in the packed bag that I'll include at the end of the review (so that way only people REALLY interested will have to see my not so good Iphone shots).
So the way the bag is packed, it can hold my DSLR with the Canon 85mm 1.8 attached (in the empty space not pictured), a little Canon 35mm 2.0, the giant and heavy Sigma 35mm 1.4, a flashlight (the blue thing on the right), My Contax G1 rangefinder with strap, and a roll of Fuji film on top of the camera. I don't think this bag could easily hold a lens as large as the Canon 70-200 2.8, but it just might be possible. I think Tamrac's claim that the bag can hold a camera and 4 plus lenses is only feasible if you are using at least a few compact lens models (the Canon nifty Fifty comes to mind) but is not totally misleading. Anyone using a Fuji or Panasonic mirrorless system could put their whole life in here and probably have room left over for a sandwich and a book. Those of us using bulkier gear can still get a few big L series pieces with our camera inside.
The lid of the main compartment has three pockets constructed of a see through mesh plastic material that Tamrac calls 'Windowpane Mesh'. I use these pockets every time I pack for a trip, usually as a second home for batteries, or for the extra stuff I take to photo shoots including small props, Cliff Bars, and paperwork (maps, directions, model release). If I had something important and compact, this is the go to spot to keep it safe, secure, and dry.
Now on to the other features that I enjoy about this bag. The first is a mesh pocket at the bottom of the front of the bag. I jammed a pair of Submarine Socks from Best Made Co. into the space to test it's capacity. I always have cold feet, so on a winter photo adventure I would bring extra socks every single time.
