It is a decent camera but I doubt you will notice to much difference to what you use ,the c-af is much better than my gx8 for sure also dynamic range has been improved I have been shooting air shows at is0 100 and like the results more than my em1.2 the view finder is very nice but with dfd pumping on occasions it makes the experience less enjoyable ,The c-af works well in some instance and occasionally get good bif results but it still fails when subject is in the wrong light or confusing background mostly when subject is coming towards you ,I have not tried much in the way of settings and what I have tried seemed to make little difference ,you would notice a bigger difference say using the pl200mm with the g8 over a g9 with say the 100-400mm not what you to hear because the 200mm is expensive to the point of luxury status.
I go along with what mirrorlessons review says about the g9 and bif it falls a little short compared to competition imagine if they put pdaf on sensor it would be a dream . quite often you have to acquire focus on a nearer point of subject to focus on your chosen subject which can be frustrating in a static situation the iq differences are there but not massive not like going from a g9 to a a73 ,I have been a little underwhelmed with mine think I have some dead pixels which show up in dxo as red also the rubber grip has come of mine just like my omd em1.2 it is now on its way back to wex.
Features are still a little gimmicky 20fps ,60fps 6k photo pre capture hi res not what you will use in most cases of use but are there if want to ,if you had the choice of a camera with 90% hit rate in c-af or the features mentioned pretty sure what most would choose .
maybe the 20mp sensor performs best with sharper lenses against the 16mp sensor but the camera body does hold some pluses over the g8 joystick is nice and top lcd which I occasionally use longer battery life the on/off switch is well thought out nice button layout and new interface extra ibis could hold some advantages .
But for the money it offers a lot that most cameras do not 4K 60p half decent c-af tracking in video ,super high frame rates ,time lapse in camera wish there was panaorama mode ,the best m43 sensor for dynamic range although not at iso above 800 but better iso performance with regards to detail .
Trevor I am sure you will enjoy it if you do purchase it and carry on winning competions.
