Focus behavior is excellent, and the camera has a fairly good burst rate and the buffer depth to back it up.
The resolution of that viewfinder is the same as the a7III 2.
Normally camera bodies this size are reserved for APS-C sensors but the Sony A7C offers the best image quality in a pint-size package.
I made the subsequent video all about using Gyro Data on the Sony A7c as while it has huge potential, there are a variety of technical aspects to remember, most notably employing a wide lens to accommodate the crop and a faster than normal shutter speed to minimize motion artifacts.
Users can also adjust the speed at which the camera changes focus and the AF system's sensitivity to new subjects as they enter the frame.
To turn off the audio signal on your cameras, simply hit the menu button at the back of your camera, go to the custom operation 2 panel under Camera 2 tab on page 10, and toggle the Audio Signal off and that is it.
