Replying to Panasonic GH4/m4/3 owners whatup?

Good day m4/3ers of M&A. I just converted from longtime canon (550,7,5) to a GH4, and in that stage of familiarising myself with this new thing. Interested to know a few things:

What UWAs go people use on these damn 2x crops?! (I just bought a speedbooster because seems like im pouring my money out spending mad coin on non-FF glass)

Then in saying that, i will shoot every other focal length on the speedbooster because committing to m4/3 specific glass seems criminal (When i can grab some old FF or rokinon stuff for relatively cheap)

I have a few ENG lenses i hope to adapt for use at the long end (and hopefully a nice run and gun rig) so should make for some interesting experimentation.

Im intrigued at the "Image App" wifi app for monitoring on my brushless gimbal, Is there a way to make the live view full screen so as i can see a 4" image on an iPhone 5 rather than that shitty wee 1.5" square in the corner? (Just for monitoring and changing settings, not pulling focus etc however, it doesnt seem THAT laggy for a wifi tether)

Also, general discussion!
