No pics to post up yet, but received my z6 today. HUGE difference with my d700 shooting experience, and all for the better. All my gripes with the d700 (af point spread, viewfinder coverage, loud shutter, etc) have all been addressed and then some.
I could definitely have stayed with the d700 for the rest of my shooting days, but I am so happy to have upgraded. I look forward to at least a decade of shooting with the z6. Pics soon to come...
