I'm typically (but not always) a trailing edge buyer.
I see that I can get a new G9 for about 40% of the price of a G9mkii.
Is the G9mkii really that much better? What does it bring that makes worth $1000USD more?
I've been using the 20MP sensored M43 Panasonics since they came out. I currently have a G95 and a G100, and an S5 for lower light, better DR.
I had no plans to get the G9II, as I like smaller M43 bodies. BUT. B&H had the $500 off promo, with a trade (can be a lens also, by the way), and they have a credit card which if you use, you do not pay sales tax, which was another $100 savings. So I said, what the heck...
I can honestly say that I have been utterly shocked at the difference between the 20MP sensors in my other M43 bodies and the current 25MP sensor in the G9II. No, it is not FF, so it's still not the best choice for low light/high ISO work. HOWEVER. Since I shoot a lot of subjects with subtle color shading and shifts, I am particularly sensitive to how well a camera captures these things, and the G9II is a huge advance in that area vs the older sensor.
Of course, not everyone shoots what I do, and not everyone is going to notice this, but it just jumped right out at me immediately, even on the first set of shots I took with it. I have not had a chance to really put it through its paces as it's been super cold here this week, but what I have gotten out with it with has been very impressive.
Oh, and the AF is a huge, huge, advance over the DFD, esp if you are shooting animals.
And, it's actually comfortable in hand. Surprisingly enough, even though it's the same size as the S5, they changed the grip just enough to make it a lot more comfortable to hold for me. They smoothed out the thumb ridge so it doesn't cut into my hand, and they changed the strap holder to a flush one, which is a much better design (IMO).
The other thing is, if you get the new model, you are guaranteed to get firmware updates going forward, which you will not get anymore for the older bodies.
So, I would, if it is at all in the budget, definitely get the new one...
