此前传闻索尼会在这个月21日推出令不少人期待已久的A7 IV全画幅微单相机，新机的规格已经多次传出，业界关心的会是A7 IV是否使用新研发的3300万像素全画幅CMOS感光元件，以及内置的4K 30p视频是不是以7K超采样，毕竟A7 IV 会是索尼未来的重点机种之一，在拥有自家生产感光元件的能力下，若不在影像核心部分下功夫的话，很难在未来数年与佳能或尼康的同级机种展示优势。而最新有消息流出的，就是索尼会先在A7 IV推出前一星期发表FE 70-200mm F2.8 GM OSS II。
索尼FE 70-200mm F2.8 GM OSS于2016年推出
在2016 年推出的索尼FE 70-200mm F2.8 GM OSS距今有五年，以“镜龄”来说还称不上是一支很旧的镜头，但是若与佳能或尼康的全画幅幅微单70-200mm F2.8镜头比较，索尼FE 70-200mm F2.8 GM OSS在技术上难免逊色了一点，而且属副厂的腾龙的后劲也愈见凌厉，刚刚为索尼ER卡口推出的全画幅微单镜头35-150mm F2-2.8 Di III VXD就非常受欢迎。
或许FE 70-200mm F2.8 GM OSS II在光学结构即使与上一代没有大改动，原来的Nano AR涂层技术几乎肯定会用上 Nano AR II，与FE 50mm F1.2 GM 及 FE 14mm F1.8 GM等看齐，进一步减少新镜头在逆光拍摄下出现的内反射、光斑和鬼影等问题。至于在FE 70-200mm F2.8 GM OSS 上的RDSSM环型驱动超声波马达和双线性马达来分别驱动前方和后方对焦镜组的对焦驱动技术也可能会更新，取而代之的是会加入多组可以提供高推力的 XD（极致动态）线性马达，提供更精确的自动对焦和追焦效果。
Cultural China: Filial piety stories in woodblock painting remain popular******
TIANJIN, Oct. 21 (Xinhua) -- Huo Qingshun is highly familiar with the Yangliuqing woodblock prints displayed in a gallery in north China's Tianjin Municipality, as he is not only an inheritor of the centuries-old craftsmanship but also knows very well morals of the stories described in the artworks.
The Yangliuqing woodblock painting was one of the most popular forms of New Year decorations in China, which flourished in Tianjin and the surrounding areas during a period between the late Ming Dynasty (1368-1644) and the early Qing Dynasty (1644-1911).
The printings contain abundant themes and content, especially traditional Chinese virtues such as filial piety, harmony and benevolence. Many of these stories described in these prints usually remain widely read and promoted in China today.
One idiom, named "Shan Zhen Wen Qin," tells that Huang Xiang, whose mother died when he was nine years old, did his best to take care of his father. During the hot summer, the young boy cooled his father's bed with a fan, and when the weather turned cold in winter, he warmed his father's quilts with his body.
When Huang grew up, he became a government official. He even gave everything he had, salary and property, to save people affected by floods.
Another printing, "Qi Guan Xun Mu," depicts that Zhu Shouchang of the Song Dynasty (960-1279) did not see his mother for 50 years as his father's first wife envied his mother and drove her out, when he was seven.
During the 50 years, Zhu missed his mother all the time and looked for her wherever he went. Zhu finally decided to give up his official position to search for his mother. After going through all the hardships, he finally found her when she was in her 70s.
"Those stories are among the 24 Filial Exemplars, a classic text of Confucian filial piety passing on since the Yuan Dynasty (1271-1368), showing the filial piety, a traditional virtue that has been highly valued by the Chinese by generations," Huo said.
"I was obsessed with my father's pictures since I was a child, and what attracted me more were the stories behind the pictures. I always looked forward to my father telling me," recalled Huo, who was born in 1950 and began to learn Yangliuqing woodblock prints from his father at the age of five.
"I gradually fully understood the profound meanings of the stories as I got older, which have also had a positive influence on my life," Huo said.
As an inheritor of Yangliuqing woodblock prints, Huo works with the gallery to pass on the craftsmanship.
"From Huo's introduction, I got to know the ancient artworks and the profound cultural connotations, which taught me to promote filial piety, respect and love my parents," said Peng Yudan, a visitor who visited the gallery.
As China has entered an aging society, the forms of filial piety are changing. Among some popular filial exemplars spreading on the Internet today, people are asked to call their parents every week, visit parents with their children often, buy insurance for parents, as well as teach parents to use computers or cellphones.
