The equipment I am taking along
The Nikon I usually take for long exposure landscape and architectural images such as waterfalls and cityscapes whenever weight is no issue.
The Fuji is on all other occasions where weight or space is an issue.
In a more predictable environment and for longer trips I like to bring additional lenses, including a wide angle zoom for night sky as well as telephoto zoom, a laptop and external hard drive to store my images.
I carry my gear in a Lowepro Flipside on day hikes. What I like about this pack is that the inside gear pouch is removable which allows me to put it into a bigger backpack with my camping gear on long distance hikes.
The tripod I use is a Gitzo Traveler Lightweight.
