She said their paths had diverged “for some time.” The announcement came after Giambruno, an on-air television personality, was caught on audio seemingly making lewd remarks to colleagues.An Italian satirical news program, Striscia la Notizia, aired two nights' worth of programming on Giambruno this week, using backstage clips and audio. Striscia is a primetime program of the Mediaset broadcaster of the late Silvio Berlusconi, whose Forza Italia party is a junior partner in Meloni’s government.This week marks the first anniversary of Meloni's government, Italy's first headed by a woman and first hard-right-led administration since the end of World War II.Meloni, who was raised by a single mother after her father abandoned the family, and Giambruno share 7-year-old Ginevra. Meloni had previously described Giambruno as a “fantastic” and very present father who complemented her in caring for their daughter. In her 2021 memoir “I am Giorgia,” she said Giambruno wouldn’t balk if she was working and he had to step in, though she complained that he was messier than she.In her statement, Meloni thanked Giambruno for their relationship and daughter and she would defend their friendship. “And I will defend, at all costs, a 7-year-old girl who loves her mother and loves her father, as I was unable to love mine.”She also hit back at the media coverage that preceded her announcement, blasting “all those who hoped to weaken me by hitting me at home.”。A6400的主要优点之一是它的自动对焦功能。该相机具有425相位和对比度检测自动对焦功能，覆盖了84%的图像区域。

C | 索尼声称，自动对焦系统是世界上最快的，锁定物件只需0.02秒。A6400还引入了索尼新的高级“实时眼AF”和“实时跟踪”功能。实时眼AF是索尼眼AF技术的最新版本。它使用基于人工智能的目标识别来检测和跟踪眼睛，提高了准确性、速度和性能。”在所有的自动对焦模式中，相机现在可以自动检测到物体的眼睛，并用半按快门按钮激活自动对焦。在AF-C或AF-A模式下，可以选择首选的眼睛（左或右）作为焦点。选择包括自动/右眼/左眼，开关右眼/左眼功能也可以被指定为自定义功能。“索尼还将扩大动物的眼睛跟踪，这是野生动物摄影师的一个宝贵功能。该功能将在2019年夏季通过摄像头固件进行更新。实时跟踪还使用相同的基于人工智能的系统来识别主题，并确保它们被准确捕获。”实时跟踪是一种新的物体跟踪功能，跟踪焦点中最具挑战性的运动物体。在半按快门按钮时选择要跟踪的任何主题的能力提供了新的框架灵活性，允许用户更多地关注图像。如果焦点在一个人身上，那么人工智能将被用来实时检测和跟踪对象的眼睛和脸，以达到非常高的跟踪精度。A6400的背面是一个3英寸、180度倾斜的触摸屏LCD显示屏，非常适合自拍和视频博客。EVF上方是一个236万点xga Tru取景器OLED电子取景器。
