The ASUS ZenFone 7 Pro Review: The Triple Flip-Cameraby Andrei Frumusanu on September 1, 2020 3:00 AM EST
Camera - Low Light Evaluation
Low-light capture of the ZenFone 7 is actually an interesting topic as we had seen ASUS’s night mode implementation in the ROG3 perform quite well when it comes to its algorithms for computational photography, albeit being handicapped by the lack of OIS.
The ZenFone 7 Pro does have OIS so we should see quite improved low-light photography results. It’s important to keep in mind though that the results posted here are only representative of the Pro variant, as the standard base model doesn’t feature OIS, with results likely much worse than what’s presented here.
The first scene is actually quite impressive as the ZenFone is able to achieve a quite excellent results that is very competitive and easily beats the shots of the iPhone 11 and the S20’s. The OIS allows the phone for a longer exposure compared to the ROG3 and to fill in more of the shadows of the scene.
The ultra-wide also benefits from night-mode and the newer sensor, however the result remains quite blurry compared to what the S20 is able to achieve.
The telephoto module in low-light isn’t very good – in this instance it didn’t even manage to focus on the subject.
The next shot also is very much in favour of the ZenFone 7 Pro as it’s extremely comparable to the Pixel 4 picture and amongst the best results in the set.
The ultra-wide here unfortunately didn’t do well as it’s completely blurry.
When there’s a bit more light, the ZenFone also fares extremely well and it’s again quite surprising to see just how similar the ASUS device compared to the Pixel 4. The ZenFone actually wins out in details, however both phone’s colour temperatures are wrong as the iPhone is closest to the actual colour of the sodium lamps on the street.
The telephoto module here is somewhat usable albeit it’s very noisy. Night mode doesn’t work on this module.
The ROG3 already had done quite well in this scene before, and the ZenFone 7 Pro produces even sharper image with extremely good handling of the highlights and overall processing. I would even go as to say that it’s the best performing device amongst the comparison phones.
Again, it’s the OIS which makes the difference to the ROG3 as in lower light conditions the ZenFone 7 Pro manages a 2.6x higher exposure through a combination of slower shutter speeds as well as a higher ISO level.
I would again as to say it’s amongst the best performers here as it manages to still retain a lot of detail, and most importantly it also got the colour temperature right.
Further in extreme low-light, the ZenFone 7 Pro continues to impress with its superior night mode, able to retain a ton of detail and more dynamic range than other phones.
Low-Light Conclusion - A Surprise Top Contender
Overall, the ZenFone 7 Pro really surprised me in terms of its low-light capture ability. ASUS’s Night Mode showed potential on the ROG3, and the addition of OIS really augments the whole camera system to a level that’s not only competitive with other smartphones on the market, but more often than not it actually beats them when it comes to detail and exposures.
The ultra-wide isn’t as well tuned as the main camera, and here it mostly loses out to Samsung’s night mode implementation. The telephoto module is largely not usable in low-light.
