In the bag a EOS 600D with the kit lens (EF-S 18-55mm) fits in perfectly - width 160-90 mm, height 170 mm (internal dimensions). The bag is well made and easy to open. Something bad there's no mention of the additional lens bags (ULTRALIGHT CP Lens 200 & 400); just was not written, as the raincover is to use - because you had to fiddle a bit.
