Best Value Today for a Full-Frame Mirrorless Camera? Sony A7 II
The discounted about $898 Sony A7 II looks like an excellent deal for anyone looking for their first full-frame camera, or just an easy-shooting camera for all-around use.
Sony has a proven track record of aggressively adding great features (well, mostly), and models to their lineup along with a very wide range of Sony FE lenses and many 3rd-party lenses.
Ironically, even a basic lens costs nearly as much as the camera! But the low cost of entry of the camera recoups much of that cost.

The best way to keep the cost down (not shown below) is the about $998 Sony Alpha a7 II Mirrorless Digital Camera with 28-70mm Lens.
