Went to get a G80 and ended up with an A7..tips from M4/3 and FF users?

Ok, I've been completely called out on the concept of complaining about the IBIS in the GX8 whilst buying a camera and considering lenses without any IBIS at all. Completely fair point on that one haha. I guess what I mean is, is that it is hard to swallow swapping a GX80 for the GX8 in some ways, knowing that the shutter and IBIS has been improved, whilst testing out FF seems like something entirely different altogether.

Guys, the GX8 is a fantastic camera no doubt and the staunch defense of it clearly indicates that. In fact, it is convincing me almost to get one (maybe when they get even cheaper second hand) for use with a longer zoom (100-300 perhaps) for wildlife.

Someone also questioned my use of an FZ1000. Again, this is just for wildlife when I'm travelling (safari/rainforest etc). I am not interested in BIF etc. However, these trips are not extremely frequent so I don't want to spend a fortune on this setup. However, the GX8 setup above could be great.

Honestly, I think I was getting to the point where the only lens I really thought that the IQ was special was the 20mm. The others don't quite have that pop. The 14 is unimpressive etc etc. So I was looking at getting something like the 15mm but its fairly costly so I thought hey, lets try an A7 with a 28mm which is only working out a couple of hundred quid more expensive including the camera body.

So an A7 system (upgraded infrequently) with a 28 and 50 for landscapes and travel (the vast majority of my shooting) and a GX8 with a 100-300 (I dont think I can afford the 100-400) and maybe even a 12-35 for video etc somewhere down the line in the future might be my future setup.
