Initial camera samples of the Galaxy Alpha, which went official today, have surfaced online. You can have a general idea of its camera quality by having a look at the full resolution camera samples below, though, please keep in mind that these images have been captured using a pre-release unit of the Galaxy Alpha.
The Galaxy Alpha comes with a 12-megapixel auto-focus camera with an f/2.2 aperture and a focal length of 4.8mm, accompanied by a single LED flash. Similar to the 16MP ISOCELL camera sensor used in the Galaxy S5, the camera unit on the Galaxy Alpha sticks of the body but its exact physical size is yet to be known.
