Hello,
Are you using ISO Auto mode? In such case, you cannot read the current ISO
value on A7M3 with PTP ISO property D21E: getting this property will just
return “ISO Auto” value (0x00FFFFFF). This can only be done on more recent
cameras using PTP V3 protocol by using PTP property 0xD023
Alpha 7M3 is not supported neither by Sony Camera remote SDK.
Best regards,
Jerome Avenel

Dear friends: I am a photography enthusiast and C++ developer. I encountered

Dear friends:
I am a photography enthusiast and C++ developer. I encountered some issues
while using gphoto2 to connect to a Sony A7M3 camera and retrieve settings for
ISO, iris, and shutter speed. When I use gphoto2 --get-config
/main/imgsettings/iso to get the ISO, it returns a very wide range, but what I
need is the current effective value. In comparison, the Sony Camera Remote SDK
provides methods to obtain the current value, the current valid range, and all
supported ranges. Could you please advise if gphoto2 offers any commands or
interfaces that can similarly retrieve these different ranges as provided by
the Sony SDK? We need your helps in urgent!
My code list:
cmd : gphoto2 --get-config /main/imgsettings/iso
code :
gp_camera_get_config(camera, &config, context);
gp_widget_get_child_by_name(config, "iso", &widget);
int count = gp_widget_count_choices(widget);
std:map<int, const char*> isoMaps;
for (int i = 0; i < count; i++) {
gp_widget_get_choice(widget, i, &isoMaps[i]);
}
