The ASUS ZenFone 3 Ultra (ZU680KL) Phablet Review

Page 4 : PixelMaster 3.0 Camera Performance - Photos & Video Recording

Camera Performance – Photos

The resolution of the new PixelMaster 3.0 camera is amazing. The full 22.5 MP resolution is attained with the 4:3 aspect ratio. Each picture has a resolution of 5488 x 4096 and a file size of 4-7 MB.

The noise level is remarkably low for such a high resolution sensor. The edges can get fuzzy at the edges, but only noticeable when you fully blow up each picture. The biggest issue is probably the camera’s tendency to blow out the highlights. You can see that in the clouds that lack definition, and light reflecting off the fruits and rubber balls.

Camera Performance – Video Recording

The ASUS ZenFone 3 Ultra is capable of recording 1080p and 4K videos, with both 4-axis optical and 3-axis electronic image stabilization enabled. To test its video recording capabilities, we recorded a piano performance and a koi pond in both 1080p and 4K resolutions. Check them out!

As the videos show, the optical and electronic stabilization worked very well, greatly reducing the amount of hand shake. Remember, this is a rather heavy and large phablet, so the user will tend to shake more.

The amount of detail captured, especially in the 4K videos, is amazing. However, you can also see how the highlights are blown out. This is especially noticeable in the bright background behind the pianist, and the surface of the koi pond.

Until ASUS fixes this propensity to blow out the highlights, you will lose the details in the bright areas of any image.

    It’s a pity that the Zen Phone 3 Uttra has The same screen resolution of the other smaller phones. Just seems a waste of potentially a great big display.

      They could have gone with a 1440p display, but that would mean greater cost and power consumption for arguably no real benefit. With a pixel density of 324 ppi, it would certainly qualify as a “Retina display” at the standard viewing distance.

      Remember – this is a large phablet, so we are more likely to view it at a distance. You can’t tell the difference with say, the Galaxy S7 edge, unless you compare them side by side and peek close-up.

        As all three devices have the same resolution the DPI would change depending on the display size. The Ultra would not give you anymore screen realestate just a larger display. The idea of a phablet would be to increase screen realestate to make it a more productive device compared with a smaller ( non Phablet ) phone.

        I would love to see manufacturers take the phablet size of six inches or larger and turn them into higher end devices rather than the middle spec devices we are seeing now.

          Correct, the ZenFone 3 Ultra won’t give you more pixels, just a larger screen.

          If you are viewing movies on a range of phablets at a distance of, say… 10 inches, a larger screen is arguably more enjoyable, but the higher resolution on any of these phablets won’t be noticeable.

          If you are looking to work on a phablet, then yes, the higher resolution will matter… a LOT. Sadly, the only phablet that is close to 6″ with 1440p resolution is the Galaxy Note7.

          Peter you are right!

          Im looking to replace my aging xperia z3 tablet compact which is 8inch to a slightly smaller 6+ inch phablet. But it seems non of the newer phablet are high end devices.

          Even Sony’s XA Ultra is powered by the mediocre Mediatek chipset instead of something higher end.

          The Ultra was something I was considering but the price for that mid range chipset seems a bit too much also…

          1. Peter

            Hi Terence,

            I have a real problem with manufacturers building large screen devices with questionable specifications. If these devices where cars then they would have an SUV chassis with a compact cabin being powered by a small 1.6 litre engine. What’s the point?

            Why not manufacture a large screened phablet with high end specifications and call it a flagship device. Just giving a phone a large screen without the benefit of higher resolution just makes it suitable for media consumption rather than a device suitable for media creation and productivity.

    Hi..just to ask from your experice reviewing this phone..did you noticed that the website,whatsapp and facebook app display are quite small despite the big screen size.The good thing is we can see more things in a screen.I tried changing to fonts to largest size but it is still the same
    i did comparison with xiaomi mi max..the display of a website in mi max is larger and fit the screen
    I suspected this is related DPI optimization
    Can you give some comments?

    1. Dr. Adrian Wong Post author

      That may be due to the higher resolution 1080p display. The icons and text will seem smaller, if you are migrating from a lower resolution 720p display, for example. Then again, the Xiaomi Mi Max has the same resolution.

      Unfortunately, we no longer have the ZenFone 3 Ultra with us, so we cannot confirm it on our end… 🙁
