I use the bag for my EOS 700D with 18-55 and 55-250 lenses. In addition, there is still room for additional accessories, a third lens would certainly still room. I will instead use the holidays for your wallet, cell phone and guide books. The two SD card slots are super, the third velcro pocket I keep a cleaning cloth. Front zippered compartment in is still plenty of room for 3 spare batteries. All in all, the bag is well made, the material feels good. I have wrestled with something if I really want to spend so much money and not rather back out on a cheaper model, but for my purposes I find the bag and great regret buying a bit.
