Seems like the Huawei P20 Pro will not be the only phone with a triple camera for much longer. Rumors indicate that the next LG V40 ThinQ will share the same number of cameras. And just like with dual cameras, LG shows that there is more than one way to organize them.
With the Huawei P20 Pro, Huawei upgraded its existing dual camera configuration by adding a third sensor. Most Huawei and Honor devices used a RGB and monochrome matrix, so it made sense to use it as a base for the triple camera and improve it with a telephoto lens. Take advantage of the details captured by the 40 MP RGB lens and the 20 MP monochrome lens sharpness, then simply combine it with the 3x telephoto optical zoom.
For LG, they followed the same tracks. For years, LG's flagship products are known for their use of a primary lens paired with a super wide angle lens, allowing their customers to place more objects in each photo. With the V40 ThinQ, rumors indicate that the super wide angle (or "ultra-white") will return with a goal "super telephoto". It seems that the telephoto lens will offer a 3x optical zoom, offering the same lossless zoom capability as the P20 Pro.
