The hard-case camera bags and cases should be able to protect your camera as it is checked in with the other luggage for the long flight. The interiors of the camera bags and cases should also have thick padding to protect the camera equipment from impact and scratches. If available, it is also preferable to buy hard camera cases that are also waterproof. These camera bags and cases may be bulky to carry around but they ensure that your camera equipment is fully protected while you are traveling. If you are not traveling but you still need to carry around your camera equipment then the backpack-type of camera bags and cases would be very suitable. You can store all your camera equipment in them including extra lenses and batteries. There are even some large camera backpacks that have a compartment for your camera tripod. These type of camera bags and cases are very convenient because they can easily store all your camera and accessories. The weight of all your equipment is also evenly distributed by the two straps of the bag.
This type of camera bag ensures that both your hands are free, although you have to take the bag off if you want to get something from inside. Backpack camera bags and cases are great for bringing along when you are hiking to a location for a landscape or nature photo shoot. If you are just taking portrait photographs then the suitable bags and cases for that purpose are those that are compact. They can be those messenger-style camera bags that can store your camera and a few Camera Accessories. They are great to use because they are lightweight and you can easily access the contents.
