There is a prototype version of the 12S Ultra that has a full size camera lens attached to it. The version of the phone that was released earlier this year has a 1-inch type camera sensor on its rear, which is far larger than those used in phones and more in line with what you might find in a small camera. A full size lens and a secondary 1-inch sensor are included in the new concept.

The concept is designed to work with the M-Series. The camera system used in the 12S Ultra was co-developed by the Chinese tech giant and the German company. It says stepping up to a full-size camera lens turns the phone into a professional photo-making tool, rather than the software-based background blur found in most phones.

It's an interesting idea. Computational photography has made huge leaps in recent years by overcoming their modest sensor and lens hardware. That raises the question of what results you could get from combining the hardware of a flagship phone with the artificial intelligence of a camera. The concept of the Moto Z follows in the footsteps of accessories like the Moto Mod.

The concept phone would be able to process photographs and shoot in 10-bit resolution. Software features like focus peaking, zebra lines, and a histogram are included in the camera app.

The company has been content to let previous concept devices remain as concept devices, like this one with a quad-curved waterfall display that was announced in February.
