No, if you want to use iTTL. Yes, if you want to use auto thyristor. If the latter, and you use it in the 'dumb' way--no communication between flash and camera--all you need do is plug the sync cord into the camera. You'll need to set the ISO and f stop on the flash.
If you want communication and focus assist (not sure about auto zoom), you'll need the appropriate SCA adapter. You'll find that info on the Metz site.
