Hello. It's my camera lens out of focus? I rotate lens but i think i didn't focus right too. It's a 16 mpx sensor, i thinking image must be detailed in good light. It's lens focused correctly? Thanks in advance.

That's not a good image to tell. It looks over compressed, but that doesn't tell you anything.

...someone of the specialists an idea for example how to set the focus a bit further away, because despite adjusted lens the focus is to near.
Or setting the AF to better values, by using that commands.
Thanks

How do you see this Xiaomi Yi?

 

[gente]

...it is focussed very good, nice pictures. Good sharpness near and far. Amazing colours, looks great!
Ok you have perfect light situations for footage.

No refocusing.
Just out of the box, the day is clear and good light *around 10am in the morning here.
I've tried to make some close images, distant images and some contrast.
Did not tried the video yet.
It has latest official firmware, no modified script yet.
