The OnePlus 7 Pro has quickly become one of the most raging flagship smartphones released this year as it came with a plethora of features and a fraction of the price compared to its rivals in the market. OnePlus used these features as the selling arguments for the OP 7 Pro in the market. Among these arguments, the claim of the 3x optical zoom was one of the most significant ones. Android Police says with proof that this claim by OnePlus is a false one.

Android Police is a popular tech news outlet which is dedicated to exposing false claims in the tech industry. The website reported that the OnePlus 7 Pro’s camera setup is only capable of 2.2x optical zoom. The additional 0.8x zoom is achieved by programmatically cropping the picture to enlarge it on the display. This kind of camera zoom is called a hybrid zoom, not an optical one.

This happened when a few early users realized that the camera setup has something fishy going on. The smartphone has a wider Field of view in portrait mode than in 3x zoom mode. Furthermore, OnePlus 7 Pro uses only the telephoto camera in portrait mode. If the smartphone really was capable of 3x optical zoom, there shouldn’t have been any difference in both modes. A clear difference proves that software manipulation is involved.

OnePlus 7 Pro, What’s up buddy?

The telephoto snapper used in the OP 7 Pro is 13 MP but the manufacturer advertises it as an 8 MP camera capable of achieving 3x optical zoom. In simple words, the whole 13 MP is being used for portrait mode, but the output of the sensor is cropped digitally in 3x zoom mode to achieve the feat. OnePlus also talked about this in a very cunning way in an interview with Android Central: “The OnePlus 7 Pro has 3x zoom with no digital zoom or loss of detail. The telephoto camera serves two main purposes: 3x zoom and portrait mode photography. It will switch the field of view depending on the camera mode. With 3x zoom, the telephoto camera delivers the advertised lossless 8 megapixels images. Portrait mode utilizes all 13 megapixels from the sensor in the telephoto camera.”

All of this beating about the bush is confusing the community greatly. A camera information outlet known as Digital Camera World says that OnePlus is using the image data from the 48 MP pixel and compositing it with the telephoto camera’s data to achieve the so-called optical zoom in its pictures. While this method is using software to manipulate the image, the concept is completely different from the hybrid zoom. Hybrid Zoom uses upscaling techniques to clarify the image while OnePlus 7 Pro is cropping the image to enlarge it.

The resulting image quality at 3X zoom is very good and people are loving it. But it still raises the point that OnePlus didn’t have to make false claims to make the market love its smartphone.
