Van der Poel breaks world record to win men's 5,000m in World Cup speed skating******

SALT LAKE CITY, Dec. 3 (Xinhua) -- Nils van der Poel of Sweden broke the world record to win the men's 5,000 meters gold medal on the first day of the speed skating World Cup here on Friday.。

"It did not come easy today," van der Poel said after crossing the line in six minutes and 01.56 seconds, 0.30 seconds faster than the previous record set by Canadian Ted-Jan Bloemen in Salt Lake City in 2017. "The race plan was to open below 20s, and do 8.5s (28.5 lap times), and take it down from there. We went for 6:02, that was the schedule."

Having shattered the 10,000m record last season in Heerenveen, the Netherlands, Van der Poel now holds the world record in both long distances, while he has more ambitions.。

"It would be cool to be the first guy to cross the six minutes. That's the coolest limit right now, the 1:40 in the 1,500m, and the six minutes in the 5,000m," he said.。

Patrick Roest of the Netherlands finished with the silver in 6:04.41 and Davide Ghiotto of Italy took his career first World Cup podium with bronze in 6:07.27.。

Japan had a 1-2 finish in the men's 500m with Yamato Matsui and Wataru Morishige taking gold and silver ahead of Laurent Dubreuil of Canada.。

In the women's 500m, home skater Erin Jackson was crowned with a winning time of 36.809 seconds. Angelina Golikova of Russia settled for the second place in 36.935 ahead of the bronze medal winner Femke Kok of the Netherlands, who finished in 37.017.。

Irene Schouten of the Netherlands snatched the gold of the women's 3,000m in three minutes and 52.899 seconds with the silver and bronze going to her teammate Antoinette de Jong and Ragne Wiklund of Norway respectively. Enditem。

适马正式发布18******

    今日,SIGMA正式发布18-50mm F2.8 DC DN | Contemporary镜头,这是一支小体格机身的“大三元“镜头,专供无反相机使用,兼容APS-C相机适用于L卡口、E卡口。同时这也是一支优秀画质的F2.8大光圈镜头,轻便小巧的构造,是无反相机的理想之选,恒定光圈,适应场景广泛。

F2.8大光圈变焦挂机镜头

    这支用于APS-C传感器的无反相机标准变焦镜头,拥有极致小巧且轻便的造型,可以成为您的理想挂机镜头。

    这支镜头是SIGMA首支APS-C尺寸无反变焦镜头,具有27-75mm的标准全画幅变焦范围,这使得它非常适合拍摄包括风景、肖像、扫街、建筑和活动在内的各类照片和视频。它还可以用于微距特写摄影,因为它的最大放大倍率为1:2.8*1,最近对焦距离仅为302.5px。拥有明亮的F2.8光圈,更容易进行手持微光拍摄,可以在浅景深下拍摄出具有冲击力的效果。

    依靠其步进马达对焦系统,这支镜头的自动对焦快速且安静,这在拍摄视频或快速移动的对象(如儿童和动物)时特别有用。这支镜头小巧、轻便,重量不到300g,是您首支可换镜头和全画幅机身副镜头*2的完美选择,也是在各种拍摄场景下的理想选择。

*1 最近对焦距离和最大放大倍率均为广角端数值。

*2 在全画幅相机上使用时,请切换到APS-C裁剪模式。

[主要特点]

1. 优秀画质的F2.8大光圈镜头

    SIGMA 18-50mm F2.8 DC DN | Contemporary 镜头在35mm全画幅标准下,焦段覆盖27mm-75mm的变焦范围,并在整体变焦范围内拥有F2.8大光圈。这使得摄影师在拍摄肖像和特写时,能够轻松获得理想的虚化效果。它能够拍摄出顺滑而美丽的焦外虚化,有助于承托主题集中焦点。

    这支镜头运用三片高精度玻璃磨铸非球面镜片,尽可能减少了镜片的使用总数,在保持轻量化的情况下实现了卓越的光学质量。另外,通过机身像差校正,进一步消除了畸变和眩光等光学缺陷。这些都是由SIGMA最新光学设计技术实现的,并在SIGMA唯一的工厂“会津”进行制造。

2. 轻便小巧的构造,无反相机的理想之选

    SIGMA 18-50mm F2.8 DC DN | Contemporary 镜头设计非常紧凑,与APS-C无反相机的便携性相匹配。这使得它可以成为一支完美的主力镜头,非常适合日常使用。这支镜头是目前同类产品中最小和最轻的*1,其最大直径为65.4 mm,长度为74.5 mm,重量为290g*2,但仍可以保持F2.8的恒定光圈。

    为了尽可能减轻镜头的重量,SIGMA使用精心挑选的材料来构建镜身。镜头主体使用一种名为耐热复合材料(TSC)的聚碳酸酯制成。它光滑而坚固,更重要的是,它的热稳定系数接近铝的热稳定系数。这确保了在温度变化时,镜头可以保持其使用的稳定性和良好的操作性。SIGMA在一些内部结构中使用了金属材料,使得这些部件在更轻薄的情况下拥有更高的刚性,从而确保镜头能够经得起频繁和长时间的使用。

    为使这支镜头可以在各种拍摄条件下进行使用,SIGMA设计的镜头最近对焦距离为302.5px,放大倍率为1:2.8*,这也是特写镜头的理想选择。

* 最近对焦距离和最大放大倍率均为广角端数值。

    这支镜头可以搭配“口袋全画幅”SIGMA fp相机,总重量只有712g。它还可以作为全画幅相机(在裁切模式下使用)的副镜头使用,以减轻其重量。

    SIGMA 18-50mm F2.8 DC DN | Contemporary 镜头集小巧、轻便、高性能和大光圈于一身,支持多种拍摄场景,从入门级的无反相机到视频拍摄,再到与全画幅相机进行组合,随心所欲。

Trump sues House committee investigating riot on Capitol Hill******

Former US President Donald Trump on Monday sued the US congressional committee investigating the January 6 riot at the Capitol, claiming members made an illegal request for his White House records.

Trump, in a lawsuit filed in the US District Court for the District of Columbia, asserted that materials sought by the House of Representatives committee are covered by a legal doctrine known as executive privilege, which protects the confidentiality of some White House communications.

"The Committee's requests are unprecedented in their breadth and scope and are untethered from any legitimate legislative purpose," Trump's lawyer, Jesse Binnall, wrote in the lawsuit.

Committee members Liz Cheney, a Republican from Wyoming, and Bennie Thompson, a Democrat from Mississippi, said in a written statement issued in response to Trump's lawsuit that the former president was seeking to "delay and obstruct" their investigation.

"It's hard to imagine a more compelling public interest than trying to get answers about an attack on our democracy and an attempt to overturn the results of an election," Cheney and Thompson said in the statement.

Hundreds of Trump supporters stormed the seat of Congress on January 6 in a failed bid to prevent lawmakers from certifying Democratic President Joe Biden's election victory. More than 600 people face criminal charges stemming from the event.

Trump was impeached by the Democratic-led House on a charge of inciting the attack on the Capitol in a fiery speech at a rally earlier that day. He was acquitted by the Senate.

Biden earlier this month authorized the National Archives to turn over an initial batch of documents requested by the select committee. The Archives has said it would turn over the requested material next month, according to Trump's lawsuit, which seeks an injunction halting that process.

Michael Stern, a former congressional lawyer, said Trump's strategy may be to use litigation to stall the select committee's work.

"If he is willing to pay for the lawyers, Trump could delay the production of records for some time," Stern said.

The January 6 committee has also issued subpoenas demanding testimony from Trump advisers, including political strategist Steve Bannon, who has refused to testify until Trump's assertion of executive privilege has been resolved by a court or through negotiations with the committee.

The committee has subpoenaed other officials including former Justice Department official Jeffrey Clark, Trump former chief of staff Mark Meadows, deputy chief of staff Dan Scavino and former Defense Department official Kash Patel.
