On December 7, OPPO's overseas official Twitter account released a 15 second warm-up video, announcing a demonstrator equipped with a telescopic lens.

A Retractable Cam is placed in the rectangular module at the upper left corner of the OPPO demonstration machine, which can be telescoped like the camera lens of the card machine. From the parameters marked on one side, this camera uses a sensor with a bottom of 1/1.56 inch (maybe IMX766), an equivalent focal length of 50 mm, and an aperture of f/2.4. At the same time, from the content of the video, the camera also supports waterproof when extended, and has the function of automatically retracting when falling.

It is reported that this is OPPO's warm-up for the OPPO Future Science and Technology Conference, which will start on December 14. Relevant technologies may be displayed and explained in detail at that time.

In fact, this is not the first time that mobile phone manufacturers have demonstrated the telescopic lens technology. Last November, Xiaomi announced a demonstration machine with only a single camera and equipped with the "telescopic large aperture lens technology". At that time, the official said that the light input could be increased by 300%. However, this technology seems to have been lost since then, I wonder if the telescopic lens displayed by OPPO this time will become the "OPPT" in netizens' mouth again.
