Digital Camera Bags and Cases
It is best to have the choice of two different-sized camera bags and cases. The smaller of the pair must be just right to get a single camera, perhaps two lenses plus a number of small accessories. The other, larger, case is saved for trips and large projects. As a mini photography studio, it should be able to accommodate two camera bodies, three or higher lenses and the required accessories.
If you are heading out to take shots of athletes in a cross-country race, for example, you could possibly include a flash for fill-in. For macro close-ups of a rare orchid, you would want to bring a pair of extension bellows, or close-up filters, a tripod and maybe a fold-up umbrella.
Camera Case A camera case must be just big enough to adopt your specific collection of equipment: too big and things will rattle around; not big enough so you wi be cramming things in.
Professional camera cases
The primary function for your larger professional camera cases is to protect your equipment from dust, rain and physical damage. To do this, it needs to be robustly built and have a rigid frame.
Professionals will have cases sufficiently strong enough to stand on. It will be a bit heavier to hold, but that extra bit of weight can save your photography equipment. If you are walking long distances, it could be helpful to use a rucksack which can be specially designed to be used by photographers.
Soft camera cases
To prevent the cameras, lenses, filters, as well as other accessories from rattling around, and hitting each other inside case, it must have many compartments and retaining straps. Many suitcase style digital camera cases come with a solid foam interior, from which you cut shapes that fit your equipment exactly. These camera bags and cases offer maximum protection.
