After using all sorts of cameras, from phones to medium format, I've come to the realization:

The best camera is the one you master

When you know your way around your camera, how to perform everything you need to do, and do it without thinking, you are free to pay attention to what really matters: what you are trying to capture.

Make your camera as simple as possible (shoot in P mode, or aperture priority) and master everything else you might use.

The longer you take, the faster the scene will fade. The sharper your camera, the sharper your mistakes will look.
