Is micro four thirds a good system to buy into?

Yes, for a lot of people it is. I'd pick Micro Four Thirds first for travel and hiking, where small, light kit matters more than the last stop of low-light performance.

The trade-off is real. Compared with full frame, a Micro Four Thirds sensor gives up roughly two stops in low light, and depth of field is deeper at the same framing. In return, a 50mm lens frames like a 100mm, so long reach comes cheap. The sensor guide lays out what you gain and lose at each size.

If you're looking, the OM System OM-3 and the OM System PEN are both Micro Four Thirds bodies, and the OM System M.Zuiko 40-150mm f/4 PRO is a sensible everyday zoom for the mount. For wildlife, my pick is Micro Four Thirds with a 100-400mm, as covered in wildlife and sport. Buying used saves a lot of money, so read buying used before you commit.
