One of the cameras on the back of the LG G8 is a regular 78-degree, 12-megapixel camera. The other is a 107-degree, 16-megapixel lens for ultra-wide shots.
Compared to the Galaxy S10 and its triple camera lens system, the LG G8 seems a little lacking. Not only does the Galaxy S10's wide-angle lens have a wider 123-degree angle, but it also includes a 2x zoomed lens, too.
LG did introduce video portrait mode with the LG G8, which gives that blurry background bokeh effect to videos. You can usually get that blurry background effect on videos when a subject is pretty close to the camera, but LG's video portrait mode should make it easier to get the blurry background effect against subjects at any distance.
