Test summary

With an overall DxOMark score of 90 points, the Asus ZenFone five does very well for a device in its class. In nonetheless image mode, the camera delivers a balanced functioning across all shooting situations, with mostly skilful color and exposure, earning itself a expert Photo score of 93 points. Drawbacks include some luminance racket in blue skies, even in very bright light, as well as a cyan-shift issue and occasional ghosting artifacts on moving subjects in high-contrast scenes. We accept likewise occasionally seen a slight pink cast in some outdoor scenes.

Mainly due to depression levels of detail, the Video score is a little lower at 86 points, but overall, the Asus has a lot to offer for mobile photographers and video shooters alike.

Bright light

Bright calorie-free images evidence expert color and decent item, but at that place is some luminance racket in blue skies.

The ZenFone'due south functioning in bright lite leaves fiddling reason to complain. Image detail is not quite on the aforementioned level every bit the very best high-end devices, simply it's close: colors are vivid and pleasant in almost all situations, and target exposure tends to be spot on. The Asus does specially well in loftier-contrast scenes, where information technology's capable of capturing images with a very wide dynamic range, showing good shadow item and keeping highlight clipping in brilliant areas of the frame to a minimum. The autofocus performance is ane of the best we have seen, with the system providing fast and accurate focus in all situations.

On the downside, some luminance noise is visible in blue skies, even in very bright lite; in high-dissimilarity scenes, ghosting artifacts tin can be visible on moving subjects; and occasionally at that place is a slight pinkish bandage in some outdoor scenes. None of those issues are bargain breakers, though, and overall the ZenFone 5 does a very proficient job in bright conditions.

Low light and Wink

Although in bright light the Asus comes quite close to the best devices in our ranking, the difference between it and the top cease becomes more obvious in dimmer atmospheric condition, with the ZenFone 5 images showing more racket and lower levels of detail than such devices every bit the Google Pixel 2 and the Huawei P20. Color and exposure are still good down to very depression calorie-free levels, all the same, and the autofocus arrangement performs just as well equally in bright conditions, making the Asus a more than than suitable selection for indoor shooting.

The ZenFone v delivers good dynamic range in this scene, just noise and a loss of detail become more obvious in indoor and low-light weather condition.

The ZenFone five'south wink images testify some of the same problems we've seen on many other devices. Flash images tend to evidence vignetting, and depending on illumination, slight color casts. There is too a lack of detail and texture, but portraits don't usually show any red-middle event, and the ZenFone'due south dual-LED flash can exist a useful "leave of jail" option in very difficult lighting conditions.

Zoom and Bokeh

Without a secondary tele-lens or high-resolution sensor for enhanced digital zoom, zooming is non the ZenFone v's strongest point. There is a noticeable loss of item equally soon as yous start zooming in, and coarse luminance noise and aliasing artifacts brand an appearance as well. It'southward best to leave the zoom function untouched and get closer to the subject field whenever possible when shooting with the Asus.

Bokeh mode does quite a decent job, however. Nether closer inspection, some background partition artifacts will be visible effectually the bailiwick, but blur strength and transitions are very pleasant. Further, the mode blurs the foreground in add-on to the background, making for an overall quite natural-looking effect. Simply keep in mind that dynamic range is reduced in bokeh manner compared to standard shooting, so y'all can end up with clipped skin tones, as seen in the sample below,  or a cyan-shift effect in the sky.

The Asus ZenFone 5 bokeh produces natural-looking results, but offers a narrower dynamic range than standard shooting mode.

Photograph scores explained

With a total 93 points, the Asus ZenFone 5 achieves a proficient Photo score for a mid-range device. The overall Photo score is calculated from sub-scores in tests that examine different aspects of its performance under dissimilar lighting conditions. In this section, nosotros'll take a closer look at these prototype quality sub-scores.

Exposure and Contrast

At 92 points, the Asus ZenFone 5 achieves a very good score for exposure, and dynamic range plays an important function in this. The Asus camera is capable of capturing a very broad range of tones, and images bear witness very good shadow detail, while at the same time keeping highlight clipping very well under command. In fact, dynamic range is so wide that some HDR scenes can have a slightly unnatural look. (Whether or not you like this look comes down to personal taste.)

In the comparison below you tin can see that in our HDR scene the Asus brightens the shadows noticeably more than than the Huawei P20 and Google Pixel 2. On the downside, a cyan-shift is visible in the sky.

The Asus also deals well with difficult high-contrast portraits, such equally the backlit scene below. Information technology sacrifices some highlight details in the background, but exposure on the paradigm's master subject is excellent.

In this backlit portrait scene, the subject is very well-exposed, but some highlight details are clipped in the brighter background.

We very occasionally saw slight underexposure in our examination samples in indoor light conditions, but in general, target exposure is spot on, from bright outdoor scenes down to very depression calorie-free levels, such every bit in the v Lux studio shot below. This means the camera is nevertheless capable of getting yous a usable exposure even when shooting in very dim conditions.

Our examination nautical chart is well-exposed at a calorie-free level of 5 Lux.

Color

The ZenFone five's colour performance is excellent, with a score on the aforementioned level equally the Google Pixel 2 and other high-cease devices. As y'all tin see in the samples below, color rendering is by and large very pleasant in all situations. Images are nicely saturated and vivid, simply however natural-looking. In the comparison below at that place are some differences in terms of contrast and tonality, but overall, all three devices produce nice-looking images.

We deducted some points for an occasional slight pink white balance cast and some color shading in lower calorie-free. That said, you'll have to look very closely to spot these imperfections.

A slight pink cast is occasionally noticeable (nether shut inspection) in outdoor images.

Slight colour shading (pinkish at the center, greenish at the edges of the frame) is just about visible in this studio shot captured nether 20 Lux tungsten light.

Autofocus

Autofocus performance is one of the ZenFone five's strengths, and at 98 points, the score is on the same level every bit  the Google Pixel two and the Huawei P20. The photographic camera delivers well-focused images in pretty much all situations and light levels. Even in low low-cal and with a brusk filibuster between defocusing and pulling the trigger, focus is quick and reliable, as you can see in the chart below.

Defocusing between each shot and then requesting focus, the ZenFone 5 delivered in-focus images both with a 500ms and 2000ms delay before triggering the shutter.

Texture

Noise

Texture and noise are heavily interlinked, which is why it makes sense to look at the two test criteria in conjunction. In good lite conditions, the ZenFone 5 delivers a good merchandise-off between detail and noise, but is not quite on the same level as the Huawei P20 and Google Pixel ii in the comparison below.

The difference becomes more than obvious in lower lite. In the 20 Lux crops beneath, nosotros tin can run across that the Asus camera can't quite provide the same levels of detail as its best competitors, and is also noticeably noisier in these dimmer lite conditions.

Noise tin can also be quite intrusive in bright calorie-free images, notwithstanding, with luminance noise grain commonly quite visible in nighttime blue skies in item. The best-in-class devices deliver smoother results in these situations.

Racket can be quite visible in bluish skies.

Here is another wait at noise on pare tones. As in the samples above, the difference between the Asus and its rivals in bright light is pocket-size just noticeable. Things become much more obvious in lower low-cal, where the ZenFone 5 produces visibly grainier skin tones than the Pixel 2 and the P20.

Artifacts

Image artifacts are generally well-controlled on the ZenFone five. The photographic camera's chief effect is ghosting-like fusion artifacts that can sometimes be visible in high-contrast scenes. They won't necessarily be noticed by the casual observer, simply they're pretty easy to spot if y'all're looking for them, as you can see in the sample shot of the moving mitt beneath.

Fringing along loftier-contrast edges and some ringing are fairly noticeable under shut inspection.

This crop shows the ghosting effect on the white background to the left of the hand.

On some rare occasions we have also spotted something that looks like image corruption. The lady bugs on the wall in the image below are partly desaturated, and ruddy color appears on the wall, which is in reality white. That said, we'd expect this issue to be fixed with a software update in the near future. We also deducted points for ringing and a cyan-shift effect that tin be visible in some skies close to saturation. Those are quite pocket-sized bug on the Asus, even so.

The prototype is partly corrupted, showing red to the correct of the lady bugs on the white wall.

Flash

With a score of 79, the ZenFone 5's flash performance is only average. When shooting flash images in complete darkness, the subject area in our test scene is slightly underexposed, and vignetting is quite noticeable in the corners. There is too a visible loss of detail, with the subject'south facial features rendered quite softly. Exposure is visibly better when shooting at ambient calorie-free levels of 5 Lux, but detail is however quite poor. The paradigm likewise shows some chroma noise and a pinkish color bandage towards the edges of the frame. Every bit with many smartphones, you're usually all-time off shooting without flash even in low-light situations, merely information technology'south skilful to take the option on board, just in case the lighting doesn't go out a choice.

Zoom

Zooming is one of the ZenFone 5's weaknesses. This is partly due to Asus's decision to include a super-wide-angle lens instead of a tele-lens in the ZenFone v's dual camera, just image processing leaves room for improvement every bit well. Both our comparison devices, the Google Pixel 2 and the Huawei P20, come up with single-lens cameras, but achieve better results than the Asus at a 2x short zoom range.

When using the ZenFone five's zoom function, there is a stiff loss of detail, and both aliasing artifacts and luminance noise are quite intrusive. The Huawei and Google comparison images are far from perfect, only visibly better than the Asus. It's also worth mentioning that dynamic range is reduced when zooming, presumably because multi-frame image fusion is deactivated with the zoom engaged.

Bokeh

The ZenFone v photographic camera is capable of capturing images that simulate the "DSLR-await" quite well, but some depth estimation imperfections are unremarkably noticeable around the primary subject. On the plus side, mistiness transitions are smooth and the bokeh mode blurs objects in the foreground, not just backside the discipline. The overall bokeh outcome has quite a natural look to it, with just the right amount of blur practical.

It'due south worth noting that like in zoom way, dynamic range is reduced when shooting bokeh images. This can atomic number 82 to clipping on skin tones and other bright areas of the prototype. We can often see the cyan-shift outcome in bluish skies that is caused past clipping one or two color channels.

The ZenFone 5 produces a quite natural bokeh effect, with blur not only applied to the background but as well to the foreground.

Video scores explained

At 86 points, the Asus ZenFone v achieves a slightly lower score for its video performance than for still prototype quality. The overall Video score is calculated using a range of sub-scores to give usa some indication of the device's pros and cons for shooting moving images: Exposure (79), Color (86), Autofocus (ninety), Texture (44), Racket (64), Artifacts (83), and Stabilization (76).

In many respects, the ZenFone 5's video output looks quite similar to its still images, with by and large skilful target exposure, and good color and white balance operation. In improver, the Asus stabilization system works quite well, keeping things pretty steady when holding the camera still and while walking. On the downside, orange casts are visible under lower tungsten lighting, and the autofocus, while generally quite fast and accurate, has a trend to oftentimes refocus, which can pb to noticeable differences in sharpness between frames.

Our video samples also often show a cyan-shift effect in the sky (run into sample frame grab below), merely the ZenFone 5'due south principal drawback in video mode is a lack of item. Fine detail and textures are not rendered as nicely beyond all calorie-free levels as on the all-time-in-form devices, the Google Pixel 2 and the Huawei P20, making the Asus a less preferable option for video shooting.

A cyan-shift effect is often visible in video clips that evidence blue skies.

Decision: Expert camera performance in the mid-range segment

To most users, Asus might non be the get-go brand that springs to heed when thinking about smartphones, but the Taiwanese (China) manufacturer has been showing for a long fourth dimension that it's more than capable of designing devices that can compete with the big smartphone brands. The new ZenFone 5 mid-ranger is no exception. It might not exist for you if you rely on skillful-quality zoom images, just information technology comes with an excellent autofocus arrangement, and delivers good epitome quality with excellent dynamic range in bright light across all shooting situations.

There is a noticeable drib-off in detail and an increase in image racket once the light gets dimmer, but the autofocus organization works just besides as in vivid lite, and exposure and color are prissy down to very low light levels. The video mode's chief drawback is slightly depression levels of particular across all calorie-free levels, but otherwise the Asus is capable of recording decent moving images as well, making information technology a very skilful option for anyone who values camera operation just doesn't desire to spend superlative-end money.

It is also of import to keep in mind that, equally with the LG V30, the ZenFone 5'south wide-angle lens does not have an impact on the scores in our test protocol. Withal, it is an important feature and differentiator that many users might detect useful.
