Canon 5d3 upgrade Advice

[mattpitts74]

Hi Guys, 

This is my first post here, so please be gentle with me.  I have been using the 5D3 for several years now with Magic lantern for small cooperate video projects as my main camera.  I have so far resisted the temptation to upgrade, I now also have several canon lens and recently purchased a Sony A6000 as a second camera, as they were selling them off cheap just before the A6300 came out.  There is obviously quite a difference the the picture coming out of these two cameras, so not necessarily the best matched cameras :-( 

I would be interested to hear people's views about possible upgrade routes from the Canon.  Camera's I have pondered over the last few years are are follows: - 

• Sony A7S 
• GH4 
• Canon C100 Mk2 (really out of my price range)
• Canon XC10

All of the above camera's obviously have the positives and negatives.  but  I'm always shooting on my own, in the usual run and gun situation and want something which is quick to setup and handles well for a lone shooter, with minimum hassle and grades well, with the highest biterate.
