Issue when connecting multiple CANON 6D

[theweege]

Hi,
I'm using digiCamControl to control 3 CANON 6D. If I start the program and turn on one camera, it works perfectly. When I turn on the second camera, it works fine but if I try to shoot a photo with the first one, it says "Invalid Handle. Failed to get property integer data: propertylid 1281". When I turn on the third one, it works but the other two don't, and I'm getting the previous error.
If I restart digicam, they work just fine.

I am having trouble, getting the same error with a single Canon 6D Mark II, but my error is immediate.

I should also add that I have no issues in the distributed digiCamControl application performing this same operation.

On the example application when the camera list populates at load, or if I power the camera on after launching, this is the log output:
New canon camera found !

I get "Invalid Handle. Failed to get property integer data: propertylid 1281" if I attempt to Capture after that.

Thanks.

Hi folks,
I´m having the same troube with property 1032 with Canon EOS R (two of them are connected simultaneously):

ERROR DCC [(null)] - Error initialize EOS camera object
Canon.Eos.Framework.EosPropertyException: Properties Unavailable.
Failed to get property integer data: propertyId 1032
bei Canon.Eos.Framework.EosCamera.OnError(Exception exception)

bei CameraControl.Devices.Canon.CanonSDKBase.AddAditionalProps()
bei CameraControl.Devices.Canon.CanonSDKBase.LoadProperties()
bei CameraControl.Devices.Canon.CanonSDKBase.Init(EosCamera camera)

Maybe I could give a valuable hint to the specialists there.
Kind regards, Tom

Hi,
because of my missed property ID 1032 we found the solution:

1. 1032 is 0x408 in hex.
2. This ID is defined at Canon.Eos.Framework/Internal/SDK/EDSDK.cs as
   public const uint PropID_FlashCompensation = 0x00000408;

But the used Canon EOS R doesn´t have a flash, so this has to bring an error.

@dukus Solution: Edit CameraControl.Devices/Canon/CanonSDKBase.cs:

Hint: There are a few more small problems at CanonSDKBase.cs, we corrected meanwhile. I can send you this file.

@caryreno: For your erroring propertyID 1281, 0x501 is defined as
public const uint PropID_Evf_Mode = 0x00000501
A quick check at Canon EDSDK 13.13.41 says
0x00000501 kEdsPropID_Evf_Mode Status of live view
Does you cam support this?
