Images are out of focus when using Hologram AF, typically, but not limited to, short distances and higher zoom settings. This issue will not occur with Hologram AF selected "off".
If your camera does meet the above criteria, please contact Sony to arrange for service. The inaccurate focus is the result of an improper Hologram AF focus parameter. The parameter can be adjusted by Sony Service Centers or Sony Authorized Service Centers in accordance with Sonys limited warranty.
