Apple iPhone 18 Pro 在 DXOMARK 测试中获得了 172 分的高分,在动态范围、自然对比度以及有效的防抖表现方面表现出色。该设备配备了多功能的三个镜头系统,其中包括带有可变光圈的 4800 万像素主传感器,能够拍摄出纹理与噪点平衡感极佳的高质量照片。其可变光圈是一项突出功能,可在复杂场景和集体照中自动提升清晰度。 视频表现同样令人印象深刻,提供平滑、自然的防抖效果和出色的暗光色彩还原。相机在大多数条件下表现稳定,能保持自然的肤色和一致的曝光。 然而,该设备也存在明显的局限性。它偶尔会出现白平衡不稳定、轻微的偏色以及眩光伪影的问题。虽然其中近距离变焦能力较强,但远摄表现落后于领先的旗舰竞争对手。此外,人像模式偶尔会出现主体分割问题,在复杂的逆光场景下,面部曝光可能略显不足。总体而言,iPhone 18 Pro 是一款顶级产品,它提供了精致、自然的成像风格,更倾向于真实的细节而非过度的 AI 处理,尽管它在远摄方面不及部分竞争对手。

这篇 Hacker News 的讨论围绕着对现代智能手机相机评测的质疑展开,起因是 DXOMARK 对 iPhone 18 Pro 进行的一项测试。 参与者认为,当前的评测往往缺乏技术严谨性,倾向于“AI 缩放后的劣质内容”而非原始数据。批评者指出,制造商越来越依赖激进的计算摄影处理(如基于 AI 的超分辨率和降噪),而非光学质量。用户担心这些技术会“虚构”细节或将图像推向物理极限(如阿贝极限)之外,并质疑当前测试方法的透明度。 讨论还涉及移动摄影的现状,一些用户指出苹果已失去其曾经的领先地位,被安卓竞争对手赶超,但也有人认为苹果在视频质量上仍处于领先地位。人们普遍渴望建立更标准化的对比测试环境,侧重于光圈和原始输出等硬件能力,而非当今相机评测中常见的、主观的“请相信我”式叙述。

The Apple iPhone 18 Pro camera performance is evaluated across photo, zoom, and video use cases using DXOMARK’s objective measurements and perceptual analyses to assess imaging performance across common shooting conditions. This article provides a structured summary of DXOMARK’s lab measurements and perceptual analyses to describe the device’s imaging performance.

Key camera specifications:

  • Primary: 48 MP, f/1.48 – f/4.0, 24 mm (wide), variable aperture, sensor-shift OIS, Focus Pixels
  • Ultra-wide: 48 MP, f/2.2, 13 mm (ultrawide), 120° field of view
  • Tele: 48 MP, f/2.8, 100 mm (telephoto), 8x optical zoom, tetraprism design, sensor-shift OIS

With a score of 172 points, the Apple iPhone 18 Pro delivers excellent overall camera performance, combining a wide dynamic range, improved contrast and skin tones, effective stabilization, and a well-balanced texture-noise trade-off. Its variable aperture is a particular strength, significantly improving the camera’s ability to maintain sharpness in complex scenes and when multiple subjects are present. Autofocus performance is good overall, offering a good user experience. Flare is also generally better controlled than on the previous generation, with a good reduction of diffuse flare in most situations, although green spots can still appear and flare remains quite visible when the iris is closed.

In photo, the camera produces generally accurate exposure and benefits from a wide dynamic range. Exposure can, however, be slightly low in some backlit portrait scenes, while contrast rendering in these situations remains particularly natural, providing a convincing balance between highlights and shadows. Texture rendering preserves a good level of fine detail with fewer visible AI artifacts than on some competing devices.

The main limitations are long-range telephoto performance, which falls slightly behind some competing flagship devices, and the lack of blur effect on portrait mode in night

Video performance is excellent overall, with smooth and natural stabilization even during running motion, as well as a good texture-noise compromise. Outdoor scenes benefit from the camera’s strong dynamic range, while low-light video shows improved color rendering, particularly for skin tones. White balance remains the main image-quality limitation, with visible color casts appearing in some conditions.

Pros

  • Exposure is mostly accurate, and it is supported by a wide dynamic range, contrast is very natural even under challenging conditions
  • Depth of field is automatically extended on group portraits thanks to variable aperture, which can be adjusted manually
  • Stabilization is effective, even during running motion, with smooth and natural rendering enhanced by 60 fps capture
  • Texture-noise trade-off is well balanced across most test conditions, combining high detail preservation with well-controlled noise

Cons

  • Face exposure can be low in challenging backlit conditions
  • Slight color casts and occasional white balance instabilities are noticeable
  • Long-range telephoto performance is behind that of some flagship competitors
  • Artifacts such as flare and aliasing are frequently visible
  • A noticeable brightness difference between photo and video can be distracting in the preview

The Apple iPhone 18 Pro is one of the strongest-performing devices overall in low-light conditions, thanks to strong performance in both photo and video. Images are generally well exposed, with a wide dynamic range and pleasant color rendering. White balance has also been improved, maintaining the device’s characteristic warm signature while keeping it relatively natural in low-light scenes.

Texture rendering is another major strength at night. The camera preserves a high level of detail while maintaining a well-controlled texture-noise balance, with only moderate noise visible in textured areas as a result of preserving finer details. This allows low-light images to retain a good level of natural texture without relying excessively on artificial processing.

Low-light performance is therefore strong overall, with blur effect being one of the more noticeable limitations in demanding conditions. Fine details can also occasionally be lost in very low-light conditions, although the overall balance between detail and noise remains good. In video, low-light performance benefits from better colors and a slightly improved texture-noise balance, particularly for skin tones, although some white balance casts remain visible across conditions.

Apple iPhone 18 Pro – Preserved contrast on face and slight low exposure

Apple iPhone 17 Pro – Some loss of contrast on face and slight low exposure

Google Pixel 11 Pro XL – Some loss of contrast on face also

The Apple iPhone 18 Pro delivers a very good portrait experience, producing well-rendered images with improved contrast and natural-looking skin tones. Exposure can be slightly low in some backlit portraits, but the wide dynamic range helps preserve scene information. More importantly, contrast rendering in these challenging situations is particularly natural, providing a convincing balance between highlights and shadows. The combination of controlled contrast and pleasant color rendering allows portraits to retain a natural photographic appearance

Bokeh mode provides good subject isolation, with accurate segmentation and a natural blur gradient. Background blur and spotlights are rendered naturally, contributing to an attractive overall portrait effect. However, some of the latest Vivo and Oppo devices provide sharper facial details and finer subject isolation, giving them an advantage in the most demanding portrait scenes.

The main limitations are found in fine subject separation and detail rendering. Segmentation can occasionally lack precision at a fine level, while the bokeh effect may fail to trigger in some situations. In the telephoto mode around 2x, facial details can also appear somewhat softer than on the best-performing competitors, although the overall rendering remains pleasant.

The Apple iPhone 18 Pro provides particularly strong zoom performance at close and medium distances, where image quality remains detailed and natural. Rendering is consistent at these ranges, with good preservation of fine textures and a balanced treatment of detail and noise.

Video zoom is a particular strength, with very smooth transitions between zoom levels. The camera provides excellent zoom smoothness in video, resulting in a natural and consistent experience when changing focal lengths during recording.

At longer distances, however, the camera does not maintain the same level of detail advantage seen at closer ranges. Long-range telephoto performance is slightly behind that of the strongest flagship competitors, with fine details becoming noticeably softer. This limits its ability to deliver the same level of detail when high-quality long-range zoom is required.
