John Carey on retro themed cameras:
It’s only natural for manufacturers to look back to the roots of the craft as a means to pull in photographers who crave more than what their mobile phone can offer them in regards to in camera creative control. That said, when you imagine a camera in your mind with full exposure control you imagine a box with knobs that allows you to adjust these key values quickly. In this regard, these supposed retro themed cameras are not retro, they are obvious. No touch screen or series of buttons will give you the same quick uncompromising access to control that simple task specific knobs do.
As Carey mentions, the Fuji X series is really leading the way in great camera body design. More on that later.
