I have bought a Canon EOS 650D me recently and needed for this even a pocket. So I opt for the Premium KIT Mantona. The camera fits easily in the pocket and you still have enough space for up to two lenses (depending on size). One can divide the attachments region by removable dividers in up to three areas. In the two side pockets I transport a spare battery, battery charger, data cable and an extra memory card.
The bag is also quite robust to protect the camera Optimal.
Positives: - Conveniently - Create your interior design - Plenty of space for all the accessories and one to two lenses - Robust
