>>3398475>A Sony A7Fun Fact: The Sony A7 has a fucking terrible sensor for a full frame camera, with as much or more noise than an APS-C camera of similar generation. At least to my eyes, the D7200 looks *better* at high ISO. It is so very, very not "absolutely world class low light performance".
(Fun Fact 2: The A7 Mark II has the same sensor, and so similar noise levels.)
Fun Fact 3: You don't seem to understand that there is more to a camera than raw sensor performance; the handling of a midrange body like a D7200 makes it very much an upgrade from an entry-level body like the D3200.
