Compatibility

Sony camera compatibility, stated carefully.

FocusStepper is built for select Sony cameras that support the Bluetooth remote-control workflow the app relies on.

Direct in-hand validation is currently centered on the Sony A7C with a Tamron 28-200 lens. The broader model list below reflects the current target compatibility list and may vary by camera model, firmware version, region, and lens behavior.

The current published model list spans Sony Alpha, ZV, RX, ILX, and Cinema Line bodies. See the support page for the full current model list.

Cameras without the required Bluetooth remote-control support are not compatible.
