Here’s something to think about as far as the bag vs case situation:
Cases are almost always (at least from brands like Pelican, etc) water-tight and air-tight. If you are traveling a lot by plane, this is a must as you’ll want to make sure your camera is in an air-tight place during transport or your lens could have problems.
A lot of bags (I believe) are water-resistant, which means it will keep your camera dry if it’s raining. However, these aren’t air-tight so not so great for things like air travel. The major advantage of bags is they can carry your gear around with less bulk and weight. You don’t have as much weight and space as the foam in cases.
I myself use a bag with my VX2000 and like how it allows me to transport a lot without being too heavy or taking up too much space. Of course, just as a precaution I never carry it outside if it’s raining because I myself don’t trust the water resistant claim.
