Are there any fees to sign up for the Canon Developer Support Program?

There are no fees for Essential membership. Essential support is intended for developers who would like access to publicly available materials such as escape codes, code samples and freely available documentation. Acceptance as an Essential member is automatic upon registration.

Premium membership is designed to provide support for developers directly involved in the creation of custom solutions for Canon products. Developers who need access to more in-depth information, such as SDKs, will need to request Premium level support.
Premium membership is granted at Canon's sole discretion.

There is a $500.00 annual charge for Premium membership.
