Sony has launched QX1, a wireless no reflection camera with APC-S frame. It and Sony's micro single products can use the lens in common, and support the connection with mobile phones for shooting. Olympus also officially released Olympus AIR A01 of the same type as QX1 on February 5, which uses M4/3 frames.

AIR A01 can also be used as a viewfinder with a mobile phone or independently (note that it has no screen). Its core configuration is very close to E-M10 and E-M5 II. It is equipped with 16 million pixel sensor, M4/3 frame, TruePic VII image processor, the maximum shutter speed is 1/16000s, 81 focus points, the maximum continuous shooting speed is 10fps, and the endurance is about 320. The "body" side is equipped with an independent shutter key and tripod hole, which supports microSD cards. The biggest advantage of AIR A01 is that it opens the underlying API interface. The open source feature also allows third-party developers to explore more ways to play.
