Samsung is making phones with triple cameras now and the Galaxy A7 (2018) was just the appetizer. The main course is coming early next year with the Galaxy S10, which should have an ultra-wide, a regular and a telephoto lens. We saw some incomplete specs for S10s dual camera earlier this year, but this newly leaked table purports to reveal all.
The main camera seems unchanged with a 12MP sensor (1.4µm pixels) and a dual aperture (f/1.5 and f/2.4). The tele camera appears mostly the same too, aside from the bump to 13MP (compared to Galaxy S9+s 12MP). Both have OIS like before.
The ultra wide camera is the new addition here. With 123° field of view, it should be a 12mm lens (in 35mm equivalent). Thats wider than the LG G7 ThinQ (16mm) and higher resolution than the Asus Zenfone 5z (12mm lens, 8MP sensor).
As a reminder, three Galaxy S10 models are expected to be announced with different camera setups and different fingerprint readers. The S10 name hasnt been confirmed, Beyond is the code name for the phone.
