Huawei’s P30 Pro could be the first of the company’s phones to come equipped with a quad-camera array on its rear, a watermarked photograph from Huawei’s consumer business group CEO has suggested. Yesterday, GSMArena noted that Richard Yu posted a photograph of the moon on Weibo, which included a watermark with details of the phone it was shot on. Although the exact details have been clumsily redacted, they appear to read “Huawei P30 Pro” and “Leica Quad Camera.”

Huawei has announced that the P30 series will be launching in Paris on March 26th using a teaser trailer that heavily implied its camera’s zoom would be a major feature. Previous Huawei devices, such as the P20 Pro and Mate 20 Pro, have already included rear telephoto lenses, despite being limited to “just” three cameras, so it’s currently unclear exactly what function this fourth camera could serve. It might amp up the zoom level or, alternatively, offer an extra wide field of view.

The number of cameras a manufacturer can squeeze onto the rear of its flagship phone has become a competition in recent years. Samsung was the first to include four with the Galaxy A9, which used its three extra lenses for zoom, ultra-wide shots, and depth-of-field detection. However, there are rumors that HMD’s upcoming Nokia 9 PureView could include as many as five rear cameras.

While more rear cameras are an objective specification that manufacturers can point to as evidence of their phone’s camera quality, we still think the Pixel 3 produces the best photographs out of any smartphone available. Ultimately, the best cameras are still single.
