It seems there's been a bit of a miscommunication with OnePlus' launch of the OnePlus 5. Despite the firm stating the dual-camera will feature 2x optical zoom, it appears this isn't strictly accurate; instead, it features 1.6x optical zoom, with the remainder of the 2x zoom capability being taken care of by digital zoom.

OnePlus CEO Carl Pei took to Twitter to clarify.

"Seen a bit of confusion so clearing this up. We're claiming 2x lossless zoom, not optical," he said.

The tech which allows the OnePlus 5 to make up the difference in zoom is called SmartCapture multiframe technology.

Considering OnePlus made such a fuss over camera tech it is strange that it made this slip up during its presentation. It really was just a lack of clarity in phrasing, mind you, as it can be interpreted either way, but it's clear from multiple reports of the launch that most correspondents believed the phone had 2x optical zoom. 

As BGR points out, "In fact, the launch keynote seemed to imply that 2x is the maximum optical zoom, although OnePlus never claimed that 2x represents pure optical zoom."

"OnePlus never said that 1.6x is the maximum optical zoom either, and walking away from that presentation I’d be inclined to believe that 2x represents optical zoom, regardless of whatever software tricks OnePlus would use to enhance the picture. Why else highlight 2x zoom as they did during the presentation? Why not focus on any other zoom level if both optical and digital zoom are working together?"
