Asus Zenfone 8 Camera review: Compact flagship - DXOMARK - Chuyên Trang Chia Sẻ Kiến Thức Thời Trang Mới Nhất

Launched in May 2021, the Asus Zenfone 8 is one of the currently most compact flagship-level smartphones. But don’t let the small package fool you. The Asus comes with top-end hardware, including a 5.9-inch Super AMOLED display with 1080 x 2400-pixel resolution and 120 Hz refresh rate, as well as Qualcomm’s top-of-the-line 888 chipset.

In the imaging department, the Zenfone 8 features a dual-camera setup. The primary shooter uses a 64 MP Sony sensor with Quad-Bayer technology and is optically stabilized. The ultra-wide camera widens the field of view to match that of a lens with 14.3 mm (35 mm-equivalent) focal length. You can record up to 8K footage at 24 frames per second in video mode. Let’s see how the Asus Zenfone 8 fared in our DXOMARK Camera tests.

Key camera specifications:

Primary: Sony IMX686 1/1.73” 64 MP Quad-Bayer sensor with 0.8 µm pixels, 26.6 mm-equivalent f/1.8-aperture lens, PDAF, OIS
Ultra-wide: Sony IMX363 1/2.55″ 12 MP sensor with 1.4 µm pixels, 14.3 mm-equivalent f/2.2-aperture lens, PDAF
LED flash
8K at 24fps, 4K at 30/60 fps, 1080p at 30/60 fps (4K at 30 fps tested)

About DXOMARK Camera tests: For scoring and analysis in our smartphone camera reviews, DXOMARK engineers capture and evaluate over 3000 test images and more than 2.5 hours of video both in controlled lab environments and in natural indoor and outdoor scenes, using the camera’s default settings. This article is designed to highlight the most important results of our testing. For more information about the DXOMARK Camera test protocol, click here.

Good detail in video
Effective video stabilization

Cons

Exposure instabilities in most scenes

With a DXOMARK Camera score of 120, the Asus Zenfone 8 makes it into the top group in the DXOMARK Premium segment ranking, on the same level as the Xiaomi Mi 11 and only narrowly beaten by the segment leader, the Apple iPhone 12 (122).

Good overall still image quality for the price bracket results in a Photo score of 126, very close to its direct rival Xiaomi Mi 11 (127) and a few points ahead of the Samsung Galaxy S21 5G (Exynos) at 123.

The mid-table Zoom score of 54 reflects the lack of an optical tele lens, which results in inferior tele zoom quality compared to many tele-equipped devices. The ultra-wide camera also has room for improvement, though, producing ultra-wide images that are not quite on the same level as most of the Zenfone 8’s segment rivals.

While it’s not the best option for users who like to zoom in or out, the Zenfone 8 does very well in the Video category and its score of 108 puts it among the best picks for mobile photographers in its segment. Keep reading for more details and in-depth comparisons.

Photo

The Asus Zenfone 8 achieves a Photo score of 126. In this section, we take a closer look at each sub-attribute and compare image quality against competitors.

Exposure and Contrast

In these tests we analyze target exposure, contrast, and dynamic range, including repeatability across a series of images. Tests are undertaken in a wide range of light conditions, including backlit scenes and low light down to 1 lux. The score is derived from a number of objective measurements in the lab and perceptual analysis of real-life images.

These samples show the Asus Zenfone 8’s exposure performance in daylight.

Asus Zenfone 8, usually accurate target exposure, but target exposure in HDR scenes can slightly be low to avoid highlight clipping

Bokeh

Asus Zenfone 8

Huawei P50 Pro

Best: Huawei P50 Pro (80)

For these tests we switch to the camera’s bokeh or portrait mode and analyze depth estimation, bokeh shape, blur gradient, and repeatability, as well as all other general image quality attributes mentioned above. The score is derived from perceptual analysis of real-life images.

These samples show the Asus Zenfone 8’s bokeh simulation in daylight.

Asus Zenfone 8, depth artifacts (top part of the grid, hair) and noise

Samsung Galaxy S21+ 5G (Exynos), strong depth artifacts (top part of the grid)

Apple iPhone 12, slight depth artifacts (blurred grid, hair)

Night

Asus Zenfone 8

Huawei Mate 40 Pro+

Best: Huawei Mate 40 Pro+ (82)

In these tests we shoot a selection of images in pitch-black darkness as well as with city lights in the background providing some illumination. We shoot sample images with the camera at default settings in both flash-auto and flash-off modes. We analyze all image quality attributes but we pay particular attention to exposure, autofocus, and color. We do not test night modes that have to be activated manually.

These samples show the Asus Zenfone 8’s night performance in flash-off mode.

Asus Zenfone 8, flash-off: underexposure on background, inaccurate color rendering

Samsung Galaxy S21+ 5G (Exynos), flash-off: slight color cast

Apple iPhone 12, flash-off: good target exposure and color rendering

Artifacts

Asus Zenfone 8

Google Pixel 6

Best: Google Pixel 6 (77)

In these tests we check images for optical artifacts such as vignetting, flare, lens softness in the corners, distortion, and chromatic aberrations, as well as for processing artifacts such as ghosting and fusion errors, hue shift, and ringing.

This sample shows hue shift artifacts in an outdoor scene.

Asus Zenfone 8, artifacts

Asus Zenfone 8, crop: hue shifts are often visible around clipped areas

Preview

Asus Zenfone 8

Apple iPhone 13 Pro Max

Best: Apple iPhone 13 Pro Max (80)

In these tests we analyze the image quality of the preview image and the differences between preview images and captured images, particularly in terms of exposure, dynamic range, and bokeh effect. We also check the smoothness of the field-of-view changes in the preview image when zooming with both buttons or when using the pinch-zoom gesture.

These samples show the Asus Zenfone 8’s preview performance in an indoor setting.

Asus Zenfone 8, preview: accurate target exposure but limited dynamic range

Asus Zenfone 8, final image: similar exposure to preview but better dynamic range
