I live in Tucson and our few camera stores are small. I am looking for a new camera backpack and will be in San Diego the week after next so I am looking for a camera store with a large stock of backpacks anywhere in the San Diego area. I would really like to be able to pack all my gear in the pack before I buy. I would particularly like to find a store that carries Tamrac since my current guess is that a Tamrac Evolution 8 (5788) will be my best choice. Any suggestions? FWIW, my requirements are: Must fit under seat in a 737 or larger aircraft. That limits the dimensions to 19" h x 14" w x 8" deep. I would probably be ok with a 9" depth but that is the absolute maximum depth. Pocket for 15.6" screen laptop. Room for a Rebel T1i, 17-55mm f2.8 USM, 55-250mm, 100mm f2.8 USM macro and lens hoods. Must have a compartment separate from the camera compartment to hold misc. gear such as my Nook, MP3 player, snacks, etc. If anyone has a suggestion for a bag that meets these requirements I would appreciate it. Thanks.
