Let's hope the GRiii isn't going to be one of the biggest disappointments of 2019 like the GRii was when it was announced. The new lens in the GRiii with fewer elements makes me a bit worried.
1. Probably something like a 16-35 or 24-70 since almost all of the pictures taken today are wide-angle shots.
2. My Zeiss 135/2 APO is amazing, but the Lumix 100-400 on my GH5 makes me feel very powerful
3. Sony 16-35/2.8 GM
4. None
Most of those 'prolific' gear reviewers don't really review stuff, they just play around a little with it and then give it a ' this is not to bad' verdict even if it is shit.
