Okay, I finally took the decision to make the move to mirrorless. I sold the 5DII last week and am in the process of selling the Canon equipment that I never used that much anyway. I'll hold on to a basic system around an "old" 5D for studio work but the carry-around stuff will have to go.

I want to use the mirrorless mainly for travel and light documentary-style work. I will, however, also use it a lot on the golfcourse, which makes things tricky. For example, I originally set my visor on the Fuji X-T1. Nice little camera, APS-C size sensor which is good. Weather resistant. Good EVF. But.... no matching glass! There's a 50-140/2.8 announced (which would be the weapon of choice on the course) but I found out it weighs close to (or even exceeds) 1 kg. Why o why are there no fast (preferably weather resistant) long primes?

Sony than? Nope, no decent, long but fast lenses either that can be paid for by a normal human being.
Olympus? Same thing.
Pentax? Ehrm...

So, I'm kind'a lost. What would you recommend? And why?
