在Apple Park，苹果发布了其高端智能手机的最新迭代产品——iPhone 18 Pro和iPhone 18 Pro Max。尽管它们的外观设计与iPhone 17 Pro Max非常相似，但新机型带来了一些引人注目的升级。 主摄像头系统获得了一项重大增强，现在集成了可变光圈。这一功能被描述为“手机上相当狂野的一项技术”，它利用六片叶片自动调节，以优化用户希望捕捉的特定照片设置。对于寻求更精确控制的摄影师而言，iPhone现在在原生相机应用内直接提供全面的手动曝光选项——这一进展被热情地称为“一件美妙的事情”和“听起来令人心旷神怡”。这些控制项允许用户访问快门速度、光圈和焦点。此外，为实现锐利图像而加入的一项实用功能是峰值对焦线，它们能直观地指示将合焦的区域。发言人通过表示“迟到总比没有好”来承认这些期待已久的功能。 灵动岛也获得了更新，今年看起来“略微小了一些”。在功能上，它的容量已得到扩展：不再只显示两项实时活动，现在可以同时显示三项。这使得用户可以同时跟踪导航、音乐和一个计时器。尽管发言人认为这一特定改变可能不是购买新设备的主要驱动力，但它标志着灵动岛实用性的持续演进。 在内部，iPhone 18 Pro和18 Pro Max都受益于内部改进，例如“改进的均热板”，这可能有助于提升散热性能。尤其是iPhone 18 Pro Max，将配备“更大容量的电池”。针对仅支持eSIM的型号，出现了一个有趣的细节：这些变体实际上将配备略大容量的电池，这是通过利用以前由物理SIM卡托占用的内部空间而实现的。 苹果还推出了一项旨在数字认证的新功能，名为“参考图像”。这一可选设置允许用户拍摄照片，这些照片在拍摄时即“通过加密方式进行签名”。苹果表示，这一签名使得图像防篡改，可作为其真实性的可验证证据，并确认这是一部“非AI生成的手机”。这一举措反映了确保数字图像完整性的更广泛努力。 然而，“今年价格方面有一些坏消息”。iPhone 18 Pro Max起售价为1299美元，iPhone 18 Pro起售价为1199美元。演示文稿最后展望了更多深入评测和广泛测试，尤其是关于可变光圈等新相机功能的测试，这些内容将在不久的将来发布。

At Apple Park, the latest iterations of Apple's premium smartphones, the iPhone 18 Pro and iPhone 18 Pro Max, were introduced. While their aesthetic design closely mirrors the iPhone 17 Pro Max, the new models arrive with several compelling upgrades. A significant enhancement is found in the main camera system, which now incorporates a variable aperture. This feature, described as "kind of a wild thing on a phone," utilizes six blades to automatically adjust, optimizing for the specific photo settings a user intends to capture. For photographers seeking more precise control, the iPhones now offer comprehensive manual exposure options directly within the native camera app—a development enthusiastically noted as "a beautiful thing" and "music to my ears." These controls provide access to shutter speed, aperture, and focus. Furthermore, a practical addition for achieving sharp imagery is the inclusion of focus peaking lines, which visually indicate the areas that will be in focus. The speaker acknowledged these long-awaited features by stating, "better late than never." The Dynamic Island also sees an update, appearing "a little bit smaller this year." More functionally, its capacity has been expanded: instead of displaying only two live activities, it can now show three simultaneously. This allows users to track their navigation, music, and a timer all at once. While the speaker mused that this particular change might not be the primary driver for purchasing a new device, it marks a continuous evolution of the Dynamic Island's utility. Under the hood, both the iPhone 18 Pro and 18 Pro Max benefit from internal improvements, such as an "improved vapor chamber," likely contributing to better thermal performance. The iPhone 18 Pro Max, in particular, will come with a "bigger battery." An interesting detail emerged for eSIM-only models: these variants will actually feature a slightly larger battery, made possible by utilizing the internal space previously occupied by the physical SIM tray. Apple is also introducing a new feature aimed at digital authentication called "reference image." This optional setting allows users to capture photos that are "cryptographically signed at the point of capture." Apple states that this signature makes the image tamper-proof, serving as verifiable proof of its authenticity and confirming that it is a "non-AI generated phone." This initiative reflects a broader effort to ensure the integrity of digital imagery. However, there was "a little bit of bad news on the price this year." The iPhone 18 Pro Max is set to start at $1299, and the iPhone 18 Pro will begin at $1199. The presentation concluded with an anticipation of more in-depth reviews and extensive testing, especially concerning the new camera features like the variable aperture, to be released in the near future.
