在2019年全球开发者大会（WWDC）上，Apple公司在推出新硬件和软件期间，用未发布的8K佳能摄像机来捕获高分辨率画面，展示了新Pro Display XDR的质量。根据技术总监Jonathan Morrison的说法，摄像机安装在机器人手臂上，并通过Atomos Shogun向Apple显示器提供4：4：4 ProRes 8K原始视频。

在他的视频中，Apple代表将机器人手臂上的摄像头称为“未发布的8K佳能相机”，从剪辑中可以很容易地看出它是按照公司C系列的风格设计的。有趣的是，它似乎在EF安装座上安装了Sigma 18-35mm T2。

佳能过去曾在其佳能博览会活动中展示了8K演示的摄像机和显示器，但这是第一次允许该技术在“展示”环境之外展示，并以我们认可的形式展示。

英文原文如下：Apple used an unreleased 8K Canon cinema camera to show off its Mac Pro, Pro Display XDR

During the launch of Apple’s new hardware and software at the World Wide Developers Conference (WWDC) 2019 an unreleased 8K Canon video camera was used to capture high resolution footage to demonstrate the quality of the new Pro Display XDR. The video camera was mounted on a robotic arm and was feeding the Apple display with 4:4:4 ProRes 8K raw video via an Atomos Shogun, according to tech YouTuber Jonathan Morrison who live streamed from the event.

During his video the Apple rep refers to the camera on the robotic arm as an ‘unreleased 8K Canon camera’ and from the clips it is easy to see it is designed in the style of the company’s C series. Interestingly, it appears to be mounted with a Sigma 18-35mm T2 in the EF mount.

Canon has featured 8K demonstration cameras and displays in the past at its Canon Expo events, but this is the first time it has allowed the technology to be shown outside of the ‘showcase’ environment, and in a body form that we would recognize.
