What makes the Sony Xperia Z5 camera so good?

October 5, 2015

As of the time of writing, the sony Xperia Z5 camera has conquered the top position on DxOMark and show very strong image quality, low-light and AF performance – so what makes it so good?

The specs: The Sony Xepria Z5 utilizes a  23MP 1/2.3″ Exmor RS Stacked BSI image sensor with 1.12 micron pixels, a 24mm equivalent f/2.0 Sony G lens, Hybrid AF (phase-detection and contrast-detection AF system, measured at 30ms), ISO 12800 stills, and a Pulse LED flash. The rear camera can record UltraHD (4K) videos at 30 FPS and has a Digital image stabilization (SteadyShot) with an Intelligent Active mode to improve stabilization when recording videos.

Impressive Video Image Stabilization

The Z5 camera specs are very impressive, especially in the video section. The Sony Xperia Z5 uses a closed-loop actuator that controls the lens position according to this article on pocketlint.Sony was managed to vastly improved the video IS with its Intelligent Active Mode, which seems to do an amazing job stabilizing videos as you can see in the sample video below.

In fact, this Sony Xperia Z3+ vs Galaxy S6 Edge stabilization test shows that the Xperia Z3 DIS outperforms the OIS of the S6 edge for video recording.

So in real tests, Sony’s SteadyShot digital image stabilization can even outperform an optical one. Even dxomark.com have mentioned in their review that the Z5 image stabilization is “..far ahead of the competition.


Excellent AF Performance

The Sony Xperia Z5 also shown a superb AF performance, which is again, the best yet tested on dxomark. The Z5 utilizes both contrast-detect and phase-detect AF to focus on subjects. The PDAF with 30ms ensures fast and accurate subject-tracking performance, which is very useful for stills and obviously crucial for video recording when using autofocus. The PDAF measured at 30ms, which means that the focus will lock on the subject in a blink of an eye.

Very Good Low Light Performance

The Sony Xperia Z5 also proven to be a very good low-light snapper, especially considering its relatively small (1.12 micron) pixels. The smaller pixels does affect the dynamic range obviously. That being said and considering its cons, the sensor performance does compensate for that in some degree and therefore in terms of high ISO performance, the Z5 does lag behind the competition, but it still provides a very good low-light performance nevertheless.

The Sony Xperia Z5 has shown very high performance all across the board, and this is why it has received such high ratings on lab test reviews. If you care about image quality and AF performance, you should certainly consider buying the Xperia Z5.
