The community maintains a "Camera compatibility matrix" spreadsheet. Always check that before updating your production code.
The SDK typically follows a hierarchy:
: Execute commands like EdsSendCommand and always ensure you call EdsRelease on all reference objects to prevent memory leaks. Specialized Modules canon edsdk documentation
"Use EdsSetPropertyData with kEdsPropID_Evf_OutputDevice and EdsGetLiveViewImage ." What it doesn’t say: You must first send EdsSetCameraStateSettings with kEdsCameraState_EvfMode and handle a constant stream of kEdsObjectEvent_EvfImage . canon edsdk documentation
: Stream the camera’s live view image directly to your application for real-time monitoring. canon edsdk documentation
