Hello,
Only specific cameras from Nikon, Canon and Sony are supported, here's the full list.
The alternative is a macro rail, like Stackshot or Wemacro. You can mount any camera and connect it to the macro rail control unit with a remote release cable. That way you won't get live view or control of the camera settings, but Helicon Remote will be able to move the camera and trigger photos for completely automated focus bracketing.
