The bag can hold a DSLR (also with KB-sensor and an attached battery grip) with a small to normal sized (including up to 18 cm total depth. Camera body) zoom lens plus a medium-sized (up to 18 cm in length) Zoom or corresponding flash unit. The small compartments for memory cards and spare batteries.
The bag is therefore expressly not matter if you want to go out with a large equipment, but more for a photo walk or a city trip, if you are traveling with a "small set", ie a camera and a small zoom and an interchangeable lens or flash. The bag wears Thanks to the comfortable, well-padded shoulder very well over a long period and has a fairly high level of security, because the open the camera compartment must be away from the body always, ie, the zippers face the body and can only hardly be opened unnoticed by a third party.
Who wants a slightly larger pocket in which can be next to camera lens together with an interchangeable lens still a flash or second objective or personal items such as Smartphone u. Ä. Store, which should grab the Maxima 300.
For small tours and photo walks I can Cullmann Sydney Maxima Pro 200 only recommend.
