Wanting to buy an MFT camera and a few lenses for reasons but don't know what to get. I want to shoot video too, but nothing too serious (yet). Mostly I'll be shooting landscapes, portraits, and wildlife. I have no idea if I should go with Olympus or Panasonic or which lenses are best on each system. Overall budget I'd like to keep below $5000 and I want a warranty with everything so I'll be buying new.

I've already started reading reviews and shit like that but there's just so many aspects of this I can't decide and I don't know which reviewers are trustworthy. Mostly the only thing I'm really sure about is that I probably want the Olympus 300mm F/4. Other than that I have no idea what I'm doing.
