SUMMARY
Reports indicate that the Sony A7S IV is nearing development, six years after the A7S III's release. A recently registered camera in China, codenamed WW261362, is speculated to be the A7S IV, possibly drawing technology from the Sony FX5. While details are scarce, it's expected to feature a 16MP sensor, a high-resolution EVF, and advanced autofocus, though internal RAW codecs from the FX5 are unlikely. Potential production delays are a concern due to global DRAM shortages affecting other Sony models.
