I am new to the LRTimelapse scene and have only shot thus far with my GoPro, Movo mechanical egg-timers and a Joby.  This setup has worked rather well, but I am looking to upgrade my gear.  Ideally I would like to get a track system, controller, and a dedicated Micro 4/3 camera as I currently own some lenses and various Olympus Pens.

Ideally, I would need to find a setup that is the following:

1) Rugged, simple and fast to setup.
2) Ideally minimal special parts or things that can easily be dropped in-between rocks or into the water. 
3) Great long-battery life or a system that supports easy multiple batteries.
4) Weather resistant (especially rain)

Cheers,
Hays
