Hi James, congratulations on the A7!
I too dropped my GX7 plan temporarily in excitement over the A7, before an attack of sanity prevailed as I remembered what my true goals were for my camera system and in what ways my previous system, a Canon 7D kit, was not meeting my needs. Outright image quality was not one of them. And, I can only afford one camera system. So my GX7 is on order!
I expect you made the right choice for yourself, and the A7 is going to bring you a lot of joy. cheers
