I would like to ask Sony photography users whether this distortion can be solved by modifying the parameters.

The distortion of the image can be corrected. Corrected by lens compensation.

This setting is through: Menu-Custom Settings-Lens Compensation.

After clicking the option of lens compensation, you can see three items: shadow compensation, chromatic aberration compensation and distortion compensation.

1, shadow compensation

Is to correct the dark angle of the lens, especially the dark angle of the lens with large aperture is more serious. You can turn this option on.

2. Color difference compensation

Color difference is what we often call purple edge and green edge. Of course, there are some color differences that are not obvious but will reduce the image quality, which can be improved by turning on this option.

3. Distortion compensation

Used to correct the distortion of the lens, make the lines that should be straight in the picture straight, and reduce the deformation of the picture. In fact, this is called distortion compensation, which may be more appropriate.

These three options are "Automatic" and "Off". Selecting Automatic will enable the camera to correct files in the machine.
