After an unexpected result comparing the Sony system camera Alpha 6300 with the smartphone Motorola Moto G5 Plus, I have a new competitor: my father's compact camera Sony Cyber-shot DSC-HX50V. I took the same motive with both cameras for comparison and came up with another interesting result. Both cameras take pictures of similar quality, if you zoom in you start to see the better resolution of the system camera.
On the left side is the compact camera, on the right side the system camera. The picture quality of the compact camera is great considering the small size. In the last picture you can clearly see the difference when zoomed in quite a lot.
