Does the camera crop off the top and bottom of the sensor's image in the preview? As in, doesn't the camera have a 4:3 sensor but displays a 16:9 image cutting off the top and bottom of the frame you'd get when you take a photo?
The default view and capture mode is 16:9. You have to manually change it to 4:3 if that's what you want. The sensor itself is 4:3 and cropped to get the 16:9 aspect ratio. When you make the change, what you see is what you get. Meaning, viewfinder changes shape depending on the aspect ratio so you know what will/won't be in the picture.
