This version of IDSworks baseplate + L-bracket are tested to work with the following SONY camera Models:

A1m2 / A1 / A9III / A7R5 / A7R4 / A7m4 / A7m3 / a7s3

OOlder Sony series may work (such as A7m2) but it will have a bigger gap between the L-bracket and the camera body. This because the camera body for older models are not as wide. We have develope this version of product so that it can be applied freely on as much as current Sony camera models as possible.
