Hi, thx for a really great app!

Some thoughts about improving:

1. Make horizontal sliders smaller and more transparent or even hide them. Horizontal swipe anywhere on a screen can change primary parameter, two-finger horizontal swipe can change secondary. Vertical swipe is for manual focus.

2. Make manual focusing slider more informative. Hyperfocal range (blue segment) will be very helpfull with such small sensor.

3. Make mode/focus/raw-jpg/flash modes collapsible so they won't block viewfinder.

4. If possible make shutter speed of 1/30 minimum visible (i mean in viewfinder) to user. So we can compose on longer shutter speeds.

And here is also more "serious" and "meegoish" icon, maybe you like it better:
