A | A former Ohio State University student-athlete is speaking out against Rep. Jim Jordan's bid for House speaker, saying Jordan "turned a blind eye" to allegations of abuse against a team doctor during his time as assistant coach for the university's wrestling team.Rocky Ratliff is now an attorney who also represents several other former OSU wrestlers in an ongoing lawsuit against the university."I think the wrestlers that I represent, not one of us, would back him for such a leadership position," Ratliff told ABC News Live Prime anchor Linsey Davis.He continued, "He's abandoned us for his own selfish reasons when he could have helped us. He's chosen not to. So that is not the good makings of any type of leadership or any type of leader that he would have put up with at Ohio State. It's just not. None of us wrestlers believe he should get that position."A spokesperson for Jordan, R-Ohio, told ABC News, "Chairman Jordan never saw or heard of any abuse, and if he had, he would have dealt with it."The allegations of abuse were against Dr. Richard Strauss, an Ohio State team doctor and sports medicine researcher. Strauss is accused of sexually abusing at least 177 men over an 18-year period from 1979 to 1997 -- nearly his entire time at Ohio State, according to an independent report released in 2019.Investigators determined that university officials ignored nearly two decades of accusations of sexual abuse against Strauss, who killed himself in 2006 at age 67, seven years after retiring from the university.The accusations of abuse involved athletes from at least 16 sports including wrestling, hockey and swimming, and included Strauss' work at the student health center and an off-campus clinic that he founded late in his tenure, according to the report.The university removed Strauss as a school physician in 1996 after a flurry of student complaints and reported his actions to the State Medical Board of Ohio. However, the school allowed Strauss to retain his tenured faculty position while he operated an off-campus clinic, where the report says he continued to abuse students.Ohio State University has since admitted that it failed to protect students from Strauss, paying out $60 million in settlements to some 296 victims.Jordan, who was an assistant coach on the team from 1986 to 1994, came under fire in 2018 when several former OSU wrestlers took their allegations against Strauss to the media and claimed Jordan was aware of Strauss' inappropriate behavior and failed to report it. The university then announced it was opening an investigation into the allegations against Strauss.Jordan also denied knowing about the abuse when the allegations first came out in 2018.Jordan is now facing renewed scrutiny amid the ongoing battle for House speaker. After again failing to receive enough GOP support, the congressman and chair of the House Judiciary Committee was defeated a second time after a vote on Wednesday afternoon."We believe very strongly, especially all the wrestlers that were there at the time, that Jim Jordan knew what was going on," Ratliff said on Wednesday.Ratliff continued, "Jordan should come forward and tell the truth about what happened. At least meet with the guys. He's failed to do that -- to hear our side, he's failed. You know, even if you believe what Jim Jordan says, he has never once reached out to any wrestler to say, 'Hey, I missed it. I'm sorry. How are you feeling?'"ABC News' Eric Ortega, Imtiyaz Delawala, Lindsey Griswold, and Andrea Amiel contributed to this report.。1月16日，据外媒消息，索尼今天发布了最新的反反射相机。新的A6400具有令人印象深刻的规格和一系列新功能，包括实时眼睛自动对焦、实时跟踪和世界上最快的自动对焦。

B | A6400的内部是一个2420万像素的APS-C Exmor CMOS传感器，带有最新一代的BioNZ X图像处理器。其最大ISO为3200（可扩展至102400）。它可以使用机械快门以每秒11帧的速度连续拍摄照片，或者静音以每秒8帧的速度连续拍摄照片。具有完整的AF/AE跟踪功能。缓冲区可以捕获多达116个jpeg帧或46个原始压缩帧。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。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。

C | ”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。

D | 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。

E | EVF上方是一个236万点xga Tru取景器OLED电子取景器。

F | 对于视频拍摄，A6400可以拍摄具有全像素读取和无像素合并的内部UHD 4K。

G | 索尼说，相机收集到的数据“大约是4K电影所需数据的2.4倍，然后进行过采样，以产生具有出色细节和深度的高质量4K材料。”1080p全高清图像质量可以在120 fps和高达100 Mbps的速度下拍摄。其他视频功能包括S-log2和S-log3、用于即时HDR工作流的混合对数伽马（HLG）图像配置文件、内置间隔计、AE跟踪（高、中、低）、斑马函数、伽马显示助手和代理记录。A6400的其他功能和规格包括弹出式闪光灯、内置Wi-Fi和NFC、八个自定义按钮（具有89种不同功能）、增强的菜单可用性、菜单帮助屏幕、照片星、坚固的镁合金机身和额定200000次循环的百叶窗。这是一张使用索尼A6400拍摄的官方照片：新的索尼A6400反反射相机将于2019年2月推出并以900美元（约6085元）的价格发货。它还将与16-50毫米f/3.5-5.6镜头（1000美元，约合6761元）或18-135毫米f/3.5-5.6镜头（1300美元，约合8789元）配套使用。
