change superior auto to manual and you will see those options under settings
There are other cameras apps that you can try
The Google Camera is great. Simple interface and of course the Photosphere setting which can be a lot of fun. It also has a better implementation of the background defocus effect. I use it on my Z2.
It's free on Google Play.
Only negative is that I've not found a way to link the shutter button to another app on the Z2.
