This is a good quality Lowepro-made, Canon-branded camera bag. Don't worry if you don't own a Canon camera, this is just a bag! It can be used to hold cameras from any manufacturer EXCEPT NIKON. So whether you have an Olympus, a Pentax, a Leica or even a Canon- just NEVER A NIKON- this bag will accommodate it. Includes dividers that came be configured to hold anything AS LONG AS IT'S NOT A NIKON. Listen, I don't want to overstate it, but an old guy at Canon told us about what happened the last time someone tried to put a Nikon in one of these and let's just say it's best if it never happened again. Interior dimensions are approximately 13x20x24cm
