[Xperia X] Camera autofocus or picture sharpness seems non-optimal
First the good parts, the pictures taken with Sony Xperia X are much better than previous Jolla 1/C at least in regards to color reproduction.
However, while on first glance the pictures look quite a bit better, but when you inspect them a bit closer (like zooming slightly) they're quite blurry.
To me it seems like camera's autofocus doesn't choose optimal setting, because when I manually tap the screen to refocus there seems to be a sharper version before it settles to what is chosen for taking the picture with. I should note that the pictures I've compared with so far have been in-doors, so that may play part.
But I don't know about the details of camera magic. All I know is that I've compared pictures taken in same conditions with Sony Xperia X, Jolla C and some Huawei Android phone. The Huawei produced crisp detailed picture. Jolla C provided what it could, but it was crispier in details though more grainy than Xperia X. Xperia X gave good color reproduction but the picture was blurry, like it was slightly out of focus.
Since the camera in this device should be top-notch, I'll categorize this as a bug. But it'd be good to hear other's experiences as there's possibility it's just a problem with my device.
I'm probably wrong, but I remember reading back in the days something like the top-notch image quality of the phone comes from limiting the resolution to lower than the maximum to kick in Sony's proprietary image enhancing technology that is available only on Android and requires the phone to have DRM-keys to work and if you lose the DRM-keys, the image quality goes down little bit due to missing the Sony's image enhancing.

I don't think the missing megapixels are the culprit.
ajalkane ( 2017-10-15 02:40:36 +0200 )editSimply the focus doesn't work well, if you try to focus manually sometimes (not every time) you can get the focus work properly... And this is just 1 issue of the lots with the camera. I noticed also if you change the light options maybe you can get better results, but this seems like a gambling. The thing is, most of the times in android I could get the best result with the automatic option, now I need to change the light settings + tap for the focus even more times until I get better result, but still nothing similar then before... + Video recording no comment...
liqquid ( 2017-10-15 03:07:30 +0200 )editSame here. Somehow the autofocus simply doesn't work as it should. Focus is slightly off in all test images I took so far. Especially at shorter distance where focus errors are more visible than at near infinity. In fact, the images of the front camera look sharper.
