Nowadays it is quite common that phones, laptops and such stuff have parts like camera (or just lens), speakers etc branded by another company. A company which is specialized to create those parts. There is those Carl Zeiss optics in phones, and Bang&Olufsen laptop speakers for example.

In theory, it is of course awesome that a company gives the job for another company which has more experience in making those parts. But, even Bang&Olufsen can't squeeze a complete 9.2 hifi system inside a laptop. Even Carl Zeiss can't squeeze a 10-200mm zoom lens with F1.4 for full zoom length inside a phone. All they can do is to fill the space with something very small, which actually has nothing to do with their regular products -which they are know of. Their regular products couldn't fit to the budget also. So the only difference in final product is the name of Carl Zeiss or B&O branded on top.

I have a whitewater kayak made by a company called Liquidlogic. the handles in the kayak are branded by Black Diamond, a company which has specialized to climbing gear. Sounds awesome, but brings no extra advantage to the kayak
