K&F Concept Camera Backpack, Camera Bags for Photographers Large Capacity Camera Case with RaincoverThe K&F Concept equipment that I already have is generally well made and thoughtfully designed. This backpack is no exception. It is a versatile and well-made mid-size backpack, excellent for photo gear and a laptop with accessories.- The backpack construction is very good, both materials and stitching.- Design elements (size and location pockets, dividers, choice of material) are well thought-out.- The shoulder straps are a reasonable thickness and have nicely contoured shape along with a connector to help keep the bag stable on the shoulders.- The camera gear compartment is customizable. Dividers are provided and velcro into place, so to speak.- The camera compartment will fit a decent range of gear (4 or 5 lenses and a body) and is large enough to accommodate a 70-200mm f/2.8 or 100-400mm f/5.6 lens.- The padding between the camera compartment and the laptop sleeve is only fair so care has to be taken if you're prone to jamming in a lot of gear.- The waterproof cover is standard for the genre.- It doesn't scream "photo backpack" (which is a good thing).- The flap over the main and rear pouch compartments' zippers is a reasonable safeguard against someone unzipping your backpack on you when it's on the back.Overall, the design is very effective.Misses:- There is no waist strap to share the load if you plan to walk long distances with this backpack in place.- The depth of the backpack is not great enough to accommodate the full height of a DSLR with a grip (but such a body can be laid flat).Neither hit nor miss:- To be clear, this is a mid-size photo backpack.This is a nicely crafted mid-size photo backpack and worth shortlisting. Recommended accordingly.
