索尼A7IV前哨 70******

    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。

Sequel to Chinese blockbuster "Changjin" in the works******

BEIJING, Oct. 28 (Xinhua) -- Patriotic Chinese blockbuster "The Battle at Lake Changjin" is set to have a sequel literally known as "Water Gate Bridge," with the return of stars Wu Jing, Jackson Yee, and other principal members of the original cast.

The news, broken Thursday evening by the movie's social media account, soon made headlines, generating more than 250,000 retweets in four hours of the Weibo post's release.

The new film, also co-produced by Bona Film Group and August First Film Studio, has the same directors as the original one -- Chen Kaige, Hark Tsui, and Dante Lam. Its release date is yet to be announced.

The sequel continues the story of Chinese People's Volunteers (CPV) soldiers fighting bravely in freezing temperatures in a key campaign at Lake Changjin, or Chosin Reservoir, during the War to Resist U.S. Aggression and Aid Korea (1950-1953).

It follows the CPV soldiers of the same company taking on a new task, and this time their battlefield is a crucial bridge on the retreat route of American troops.

"The Battle at Lake Changjin," hitting Chinese theaters on Sept. 30, has moved many moviegoers to tears.

It tells of how the young CPV warriors were willing to risk it all to defend their motherland from the world's best-equipped army, despite their lack of food and warm clothing and amid the bitter cold.

Raking in a whopping total of over 5.37 billion yuan (about 839.63 million U.S. dollars) in 29 days, the war epic is this year's second-biggest earner so far, both in China and globally. It only trails domestic comedy "Hi, Mom," which has raked in 5.41 billion yuan, according to data by e-ticketing platform Maoyan.

It is currently the third-highest-grossing title of all time at China's box office. Maoyan predicts the film will complete its run with 5.5 billion yuan. Enditem

Analysis: Four things we learned from Spain's Matchday 14******

MADRID, Nov. 22 (Xinhua) -- Real Madrid moved back to the top of La Liga on Sunday as football returned after the international break, while Xavi Hernandez had a winning debut at Barcelona. Here are some things we learned over the past 48 hours in Spain.。

1. Xavi has a lot of work to do。

FC Barcelona won their first game under Xavi Hernandez on Saturday night with a 1-0 victory over Espanyol, but nobody who saw the game can be under any illusions that the return of the former midfielder is going to be a quick fix.。

Xavi showed faith in youth, with 3 teenagers in his starting 11 and in the first half his side looked to be aggressive and press their rivals high up the field. However, in the second half they lost their shape and although a very questionable penalty gave them the win, with a bit more luck in front of goal Espanyol would have taken something from the game.。

The injuries don't help, but Xavi has a lot of work to do.。

2. Vinicius is at last fulfilling his promise。

Real Madrid romped back to the top of La Liga with a 4-1 demolition of Granada, partly inspired by their Brazilian winger, who not only scored his eighth goal of the season, but also provoked a red card for Granada defender, Monchu, who got his marching orders with 23 minutes left to play for a wild lunge at Vinicius' knee.。

The winger's 56th minute goal was his eighth league goal of the season -- matching the number of league goals he scored in his first three years at the club and his improvement has come at exactly the right time.。

Maybe Real Madrid coach Carlo Ancelotti has played a role in his improvement.。

3. Bordalas makes his mark at Valencia。

Real Sociedad lost the leadership after being held to a 0-0 draw at home to Valencia in a controversial game in which Valencia showed their cynical side. The team coached by former Getafe boss, Jose Bordalas committed a string of niggling fouls, most of which looked to break up Real Sociedad attacks in their own half, but they also wasted every second of time and were guilty of some blatant diving and play-acting to try and get rivals booked.。

Valencia saw seven yellow cards in the game and it could have been more, but ironically it was Real Sociedad who ended up with a player sent off after Aritz Elustondo was shown the red card for reacting after being pushed violently to the floor by Daniel Wass just a couple of minutes after Maxi Gomez has body checked him in the ribs.。

Valencia now play like Getafe did under Bordalas and referees have to be aware of their tactics.。

4. Escriba pays the price at Elche。

Fran Escriba became the fourth coach to be sacked this season after his side's 3-0 defeat to Betis on Sunday afternoon, with the club showing him the door less than an hour after the final whistle.。

Escriba will always be a hero at the club after leading them to promotion in 2013 in his first spell and then saving them from relegation in the last game of last season, but a run of six games without a win has now ended his second spell.。

Given that Elche's main ambition this season is to avoid relegation, the decision seems harsh, but it merely shows how important it is to a club's economy to stay in the top-flight and that means patience is a virtue in short supply. Enditem。
