When it comes to the Huawei P9, the only option are nano-SIMs, while one can choose between a single SIM + SD-card or dual SIM.
Anyway, we are talking photography here. Very obviously, the winner is the Huawei P9.
Below shots a certainly not side-by-side, obviously taken on different days, under distinct conditions.
Anyway, both are in-phone JPEG renderings.
Anyway, what we are looking at is a decent smartphone with a camera, versus a decent prosumer camera with smartphone functions. For a prosumer camera, the Huawei P9 might not be the cheapest, but in the lower segment. Figure that, the Huawei P9 offers a camera with almost full control (no real control over aperture though).
The Wiko Jerry is a good smartphone, with a 5Mpix shooter that resembles nothing to call home about, although decent enough to take the occasional shot to document something.
In contrast to that, the much more expensive Huawei P9 might actually be the camera you might want to use for artisan work.
For my next journey, I seriously consider to choose the P9, rather than a real camera, in particular since I get RAW files when using the P9.
The question is, 2 smartphones in the pocket vs 1 smartphone and 1 camera. Certainly 2 smartphones are easier to carry...
