Here's everything we know:
As per DigitalChatStation, the OPPO Find X7 Pro could come with a quad rear camera setup, including two periscope cameras with impressive zoom quality, a first for a smartphone. There could be a 50MP main camera (Sony LYT-900 1-inch sensor), a 50MP 2.7x optical zoom lens (Sony 1/1.56-inch IMX890 sensor), and a 50MP 6x optical zoom lens (Sony 1/2.4-inch IMX858 sensor). The fourth lens would probably be a 50MP ultrawide snapper.
We also learn about the Hasselblad XCD lens effect. Originally, XCD is a kind of lens used in medium-format mirrorless cameras. So, OPPO could be trying to recreate that effect from its mobile camera.
The Find X7 Pro cameras could benefit from the HyperTone aesthetics offered by cameras with "high image qualities for every focal length whether it's day or night," an improved processing engine, and new ProXDR displays with "up to eight times more dynamic range" and Ultra HDR standard support.
Besides this, you could get special filters Hasselblad Portrait Mode and Bokeh Flare Portrait.
OPPO Find X7 series could launch at the start of February or the end of January. We should have more details by then.
