Have an 11 Ultra since it came out and it does provide wonderful image quality in MotionCam and McPro24Fps.
Three things makes photography a difficult task on it though;
For street photography I need an app that opens fast and captures fast (preferably the native camera app)
1. When you select 5x in the camera app it crops into the main sensor instead of switching to the native zoom sensor. You have to zoom to 10x and then to 5x again to fix it, every time.
2. The audio clips even at low levels and concerts can't be recorded at all for example.
3. The processing is bad on the native app and has a lot of smoothing and way too much contrast. So raw is really the only option.
None of these was fixed for it.
Considering the 15 Ultra and it does seem much better in most respects, but I'm not sure I trust Xiaomi after all this. GCam looks great on it though, if it´s fast enough.
Anybody has any input on how 14/15 Ultra is to use in practice? The images in this thread does look great.
