lens hood -> good lens protection !
I have taken my camera in the mountains, archeological sites, cities, and I've never broken a lens or a camera by dropping, banging, or otherwise abusing it. I use a lens cap. I have broken two lens caps. If I'm not actually taking a photo, the lens cap is on the lens. That's what they're for.
I carry the camera across my chest, some call it courier style, and I've never accidentally dropped the camera when taking off my backpack or whatever.
