Overall, I am very pleased with my 6D MKII. I am coming from owning a 60D and extensively using a 6D, the AF improvements with the articulating screen was the perfect upgrade path when compared to the 5DIV.
I am going to get the 24-70II as my next lens to pair with hte body. I currently have a 100-400II and a 50f1.8 STM. The 100-400 stays on the camera about 90% of the time.
