sony models didn't like any others, like nikon they have 0x90C7 to know it takes a photo and i checked your code image I still don't know how you get the event here.

you get ptp events, the 0xc201, 0xc202, 0xc203:

ptp.h:#define PTP_EC_Sony_ObjectAdded 0xC201 ptp.h:#define PTP_EC_Sony_ObjectRemoved 0xC202 ptp.h:#define PTP_EC_Sony_PropertyChanged 0xC203

the come via specific PTP USB events.
