However, the camera does not, as many first believed based on the keynote presentation, come with a true 2x optical zoom (or more accurately, ‘telephoto’) mode.

The obvious competitor here is the iPhone 7 Plus which uses a pair of 12MP sensors in its own dual-camera configuration, but offers a true 2x optical zoom. This means the OnePlus 5 could still be delivering a higher resolution image with its ‘2x lossless zoom’ than the iPhone 7 Plus does with it’s 2x optical zoom.
