Camera straps/slings are your friends! I believe most DSLR kits come with a basic neck strap. My Canon T3i did anyway! They are not only good to protect your camera from being dropped, but they also put the brunt of the weight on your body instead of your arms.
You can even use them to help steady the camera a little by pushing the camera out so the strap is tight between the camera and your body. Works good if you are shooting video handheld and can only use the LCD screen.
I put the strap on the lens, that is when I use the Bigma, not only the strap, have to take the picture like shooting a rifle in standing position, lol.
my camera is Canon Kiss X4(T2i), love it.
18mp camera is really good, but to take good pictures you need lenses, remote flash/flashes, a sturdy tripod and most important, spend a lot of time to fully understand the concept/settings and take control of them.
try not to use any auto mode, or better to get a PNS.
One of hobbyists, takes professional grade pictures, speedie408, his pictures are from his T2i, amazing quality, you can do the same.
