Sony Xperia Z5 camera autofocus speed test: how fast is it?

At IFA 2015, we had the privilege to get our hands on Sony's latest and greatest Android devices, namely the Sony Xperia Z5, Xperia Z5 Compact, and Xperia Z5 Premium. Long story short, all three combine plenty of silicon strength with stylish glass-and-metal design, which makes them phones worth being excited about. But one of their best features is shaping up to be the new 23MP main camera all three are packing. We're promised outstanding image quality out of the new snapper, and then some!

Image quality, however, is one thing. Camera speed is a whole different story. Both factors are of importance to anyone serious about photography, and Sony knows that well. As a matter of fact, Sony has put great efforts into improving the latter – we're promised extremely fast auto-focusing out of the Z5 smartphones' cameras. Given optimal conditions, they should be able to focus on an object in as little as 0.03 seconds, which is about 10 times faster than the blink of an eye. In comparison, the top phones of yesteryear boasted focusing times of about 0.27 to 0.3 seconds. 

But is the Xperia Z5's camera as fast as Sony claims it to be, or does the record-breaking figure exist only in the realm of theory? Well, our impromptu text gives a hint, and the results are very promising. While attending IFA 2015, we took an Xperia Z5 and put its 23MP camera to the test. Firstly, we pointed it at a far object until it focused on it. Then we panned the camera quickly onto an object located about 6 inches (15 centimeters) away from the handset. Did the camera nail it? See for yourself in the video below.

Reading comments on Btekt's z5 10-minute recording and somebody shared this link about Mike R recording an almost 15-minute video on his z3+ after the firmware update. This is good for the people who already bought z3+ and who are planning to get z3+ instead of z5. I'm impressed with Sony's system addressing the issues surrounding snapdragon. If the firmware update is stable, then z3+ is still going to be a good buy and not end like htc m9.

Since many people say that 4k recording is more taxing and more of an overheating magnet than gaming, I'd like to ask the PA community if there's someone here who can tell us what happened to their z3+ after the firmware update because if it improved the device, I'll just forget z5 and just get z5c and z5p. Thanks.

The thing is that 4k recording doesn't tax the CPU and GPU that much. It uses the codec and the NAND. Using a more efficient encoding and compression algorithm can easily improve 4k recording. Almost any phone with SD 805 or above can record 15-20 minutes of 4k. The reason why manufacturers limit it to 5 minutes are the storage concerns. This update or any software update can never fix a inefficient chip like the 810. The 810 has issues with it's CPU and GPU throttling and it's a hardware issue. The chip simply can't sustain high powered state. A software can't magically apply an icepack to it. So either you throttle a chip so that it doesn't heat up, or you do thermal measures like heat pipe( Z5 has 2 heat pipes). And I'm not a Sony fanboy.

Thanks. Scientific info is much appreciated. So that will explain why even z3c can record 4k up to 40 minutes as this guy claims.

Also mobile phones don't have NTFS format of storage so storing files over 4 GB isn't possible. Thus the limit of 5-10 minutes.

Actually I'm not one of them. I actually regretting getting the Z3+ since the Z5 has new camera, fringerprint scanner and the new Sony UI. Selling off my Z3+ and planned to get Z5 Premium as soon as it release.

Question for Tyrion. Codecs can also be software based which would then have to utilize the cpu. Do you know if these phones actually have a dedicated codec device built in?

This time Sony brings out a beast of a camera with Z5. Can't wait to get my hands on Z5C.

"Image quality, however, is one thing. Camera speed is a whole different story" - The 100% view in PA tests is better, but a lot of overprocessed results :-(

Just for fun: Do you think PA should add 1080p and 4k video recording duration in their benchmarks page? Bet that will make the PA staff busy for a very, very long time.

ok, now spun that toy and take another photo (just want to check how fast it can capture image with standart ISO setting)
