I love how everything is accessible while I’m wearing the backpack so my wife can switch lenses without me taking It off.The only reason this doesn’t get 5 stars from me is that one of my lenses is too long to fit in the bottom lens compartment. The description states that the smallest interior dimension is 8.27 inches. In reality you would find difficulty fitting any lens in the bottom compartment that is longer than 6.5 inches. Other than that, I love this thing! Here is a breakdown of what I’ve got in the bag:Top compartment:Canon EF 70-200mm 1:4L USM LensDust cover for the lens that is on the cameraDust cover for the camera itselfMicro Fiber cleaning clothDust brush for cleaning the lensSide compartment (Middle)Canon 6D Mark II Camera with attached EF 24-105mm 1:4L IS II USM Lens. Note that the camera with my 70-200 lens attached will not fit in this compartment.Memory card wallet is in the zipper pouch of the side compartmentSide Compartment (Lower)This compartment is a tiny pouch for accessories that aren’t very thick. I have the following items in mine:IR shutter remoteUSB CableBottom Pouch:Canon Macro EF 100mm 1:2.8L IS USM LensLens hoods for all 3 of my lenses (nested together in one section)Battery charger (I would have put the hoods and charger in the top compartment if my 70-200 lens would have fit in here)I hope this helps give you an idea for exactly what can fit in this camera bag!
