  • Limited dynamic range
  • Low levels of video detail
  • Inaccurate color rendering and lack of saturation in video

 

The Asus Zenfone 11 Ultra is capable of delivering decent photos and video clips in everyday use but could not quite match the best Ultra Premium competitors in the DXOMARK Camera tests, achieving lower scores pretty much across the board. Exposure was good when capturing landscape photos and our testers liked the fairly accurate white balance and low noise levels in bright light conditions. However, they also noticed inaccurate skin tones, as well as noise and a lack of detail and in low light. Zoom shots lacked detail and could be noisy at most focal length setting and while video clips were stable and smooth in most scenarios, video detail was low and exposure, color and autofocus were all unstable in some conditions.

Test summary

About DXOMARK Camera tests: DXOMARK’s Camera evaluations take place in laboratories and in real-world situations using a wide variety of subjects. The scores rely on objective tests for which the results are calculated directly by measurement software on our laboratory setups, and on perceptual tests in which a sophisticated set of metrics allow a panel of image experts to compare aspects of image quality that require human judgment. Testing a smartphone involves a team of engineers and technicians for about a week. Photo, Zoom, and Video quality are scored separately and then combined into an Overall score for comparison among the cameras in different devices.

About DXOMARK Camera Photo tests

For scoring and analysis, DXOMARK engineers capture and evaluate more than 2,600 test images both in controlled lab environments and in outdoor, indoor and low-light natural scenes, using the camera’s default settings. The photo protocol is designed to take into account the main use cases and is based on typical shooting scenarios, such as portraits, family, and landscape photography. The evaluation is performed by visually inspecting images against a reference of natural scenes, and by running objective measurements on images of charts captured in the lab under different lighting conditions from 1 to 1,000+ lux and color temperatures from 2,300K to 6,500K.

In Photo mode, the Zenfone 11 Ultra was capable of capturing pleasant images in most test conditions, even in difficult backlit scenes, or when shooting in low light. However, the overall photo performance remained below the best competitors in its price segment. Our testers sometimes found subject exposure to be slightly dark and skin tone rendering could be slightly off. While the trade-off between detail retention and noise reduction was pretty good in bright light, the level of captured detail could not quite match the best in class devices. Image noise levels increased under typical indoor lighting and in dim conditions. Our testers also observed some shadow noise. In terms of image artifacts, ghosting effects could often be seen on moving subjects.

Asus Zenfone 11 Ultra Photo scores vs Ultra-Premium
The photo tests analyze image quality attributes such as exposure, color, texture, and noise in various light conditions. Autofocus performances and the presence of artifacts on all images captured in controlled lab conditions and in real-life images are also evaluated. All these attributes have a significant impact on the final quality of the images captured with the tested device and can help to understand the camera's main strengths and weaknesses.

Exposure and color are the key attributes for technically good pictures. For exposure, the main attribute evaluated is the brightness of the main subject through various use cases such as landscape, portrait, or still life. Other factors evaluated are the contrast and the dynamic range, eg. the ability to render visible details in both bright and dark areas of the image. Repeatability is also important because it demonstrates the camera's ability to provide the same rendering when shooting several images of the same scene.
For color, the image quality attributes analyzed are skin-tone rendering, white balance, color shading, and repeatability. For color and skin tone rendering, we penalize unnatural colors but we respect a manufacturer's choice of color signature.

Asus Zenfone 11 Ultra – Slight underexposure on face, inaccurate skin tones, especially the dark skin tones
Apple iPhone 15 Pro Max – Good exposure and skin tone rendering
Huawei Pura 70 Ultra – Good exposure and skin tone rendering

Autofocus

Autofocus tests concentrate on focus accuracy, focus repeatability, shooting time delay, and depth of field. Shooting delay is the difference between the time the user presses the capture button and the time the image is actually taken. It includes focusing speed and the capability of the device to capture images at the right time, what is called 'zero shutter lag' capability. Even if a shallow depth of field can be pleasant for a single subject portrait or close-up shot, it can also be a problem in some specific conditions such as group portraits; Both situations are tested. Focus accuracy is also evaluated in all the real-life images taken, from infinity to close-up objects and in low light to outdoor conditions.

Autofocus irregularity and speed: 20Lux Δ7EV Tungsten Handheld
This graph illustrates focus accuracy and speed and also zero shutter lag capability by showing the edge acutance versus the shooting time measured on the AFHDR setup on a series of pictures. All pictures were taken at 20Lux with Tungsten illuminant, 500ms after the defocus. On this scenario, the backlit panels in the scene are set up to simulate a fairly high dynamic range: the luminance ratio between the brightest point and a 18% reflective gray patch is 7, which we denote by a Exposure Value difference of 7. The edge acutance is measured on the four edges of the Dead Leaves chart, and the shooting time is measured on the LED Universal Timer.

Texture

Texture tests analyze the level of details and the texture of subjects in the images taken in the lab as well as in real-life scenarios. For natural shots, particular attention is paid to the level of details in the bright and dark areas of the image. Objective measurements are performed on chart images taken in various lighting conditions from 1 to 1000 lux and different kinds of dynamic range conditions. The charts used are the proprietary DXOMARK chart (DMC) and the Dead Leaves chart.

Noise tests analyze various attributes of noise such as intensity, chromaticity, grain, structure on real-life images as well as images of charts taken in the lab. For natural images, particular attention is paid to the noise on faces, landscapes, but also on dark areas and high dynamic range conditions. Noise on moving objects is also evaluated on natural images. Objective measurements are performed on images of charts taken in various conditions from 1 to 1000 lux and different kinds of dynamic range conditions. The chart used is the Dead Leaves chart and the standardized measurement such as Visual Noise derived from ISO 15739.

Bokeh is tested in one dedicated mode, usually portrait or aperture mode, and analyzed by visually inspecting all the images captured in the lab and in natural conditions. The goal is to reproduce portrait photography comparable to one taken with a DLSR and a wide aperture. The main image quality attributes paid attention to are depth estimation, artifacts, blur gradient, and the shape of the bokeh blur spotlights. Portrait image quality attributes (exposure, color, texture) are also taken into account.

About DXOMARK Camera Zoom tests

DXOMARK engineers capture and evaluate over 400 test images in controlled lab environments and in outdoor, indoor, and low-light natural scenes, using the camera’s default settings and pinch zoom at various zoom factors from ultra wide to very long-range zoom. The evaluation is performed by visually inspecting the images against a reference of natural scenes, and by running objective measurements of chart mages captured in the lab under different conditions from 20 to 1000 lux and color temperatures from 2300K to 6500K.

The Zenfone 11 Ultra’s 3x optical tele zoom offered decent image results when shooting in bright light, but lacked quality at close and long range settings. In more challenging conditions, such as low light, noise could be quite intrusive and images lacked detail. In addition, our testers observed some exposure errors, resulting in underexposed images. The ultra-wide camera delivered a good performance in bright light, but showed limitations indoors and in low light. Skin tones often looked unnatural and white balance casts could be noticeable.

About DXOMARK Camera Video tests

DXOMARK engineers capture and evaluate more than 2.5 hours of video in controlled lab environments and in natural low-light, indoor and outdoor scenes, using the camera’s default settings. The evaluation consists of visually inspecting natural videos taken in various conditions and running objective measurements on videos of charts recorded in the lab under different conditions from 1 to 1000+ lux and color temperatures from 2,300K to 6,500K.

Overall, the Zenfone 11 Ultra’s video mode left quite some room for improvement. The camera often got exposure wrong when recording in bright light or indoors. While white balance was neutral, some exposure and color transition issues were noticeable. The autofocus generally did a good job at keeping the subject in focus, but was unstable with some stepping. Video noise levels were low, but so was the level of recorded detail. While video stabilization was generally quite good at counteracting camera motion, some camera shake tended to be noticeable in the most challenging scenes.
