Does it suitable to my camera?

Currently, this project is based on Canon SDK (PS-ReCSDK 1.1.0e) definitions.

The SDK lists the follow cameras:

• PowerShot A620,
• PowerShot S80,
• PowerShot S3 IS
• PowerShot G7
• PowerShot A640
• PowerShot S5 IS
• PowerShot G9
• PowerShot SX100 IS
• PowerShot G10
• PowerShot SX110 IS

You can get detailed info here.

You can adapt the code easily to work on Canon EOS cams and some Nikon ones, due ArduCam board is compatible with Oleg's PTP library.

By other hand, there is a PTP hacking extension in course at CHDK project. The ArduCam project's goal is use that nice resource on future, for extending the PTP control to other newer Canon models, which are small and light.
