Missing features: Only one C button, no front thumb wheel, no joystick Thus quick selection of focus mode, focus area, peaking level, peaking color, let alone brightview and manual control of focus mag, will require programming to the Fn button fields which I've found to be slower and more difficult to use. In this regard for better ergonomics in a small rangefinder-style body use an a6500 or a6600, both less costly. For the intended more casual use in the targeted market where shallow dof and best ability to rescue shadows are beyond concern, APS-C is more sensible, too. My kit remains a7Riii, a7iii, a6500 (purchased in reverse sequence).
Funny that so many early reactions to this are focused on a few missing buttons. I don’t think Sony aims this at pros. To this noob it feels like Sony is aiming it at street photographers who covet the Rx1r but can’t swing the price. This lacks the resolution of the Rx1r ii but swapping lenses and half the price? They’re gonna sell quite a few.
