Rumors say Sony has registered a new camera in the US under the code WW491229. The listing reportedly shows Wi-Fi 6 support, the NP-SA100 battery and testing with the XQZ-UC1 charger. The report says this model seems to correspond to the earlier WW261362 filing, but it stresses that the link is not confirmed.
WW261362 was registered in China in late September by Sony Japan, also with Wi-Fi 6. Sony Alpha Rumors read it as a mid- to high-end model and bet on the a7S IV. The a7S III is now about six years old. Sony Alpha Rumors also speculated that a November launch might be possible, and that the DRAM shortage could affect timing. Sony has not announced a camera, a name, a price or a date.
A second registration in a different region suggests the product is moving toward launch. Regulatory filings usually come some weeks to months before an announcement, but they do not reveal the model name or specifications. For owners, the a7S IV remains the most discussed candidate, a video-focused full-frame body. An FX-line successor or another model is still possible. Treat the identification as unconfirmed.
