The 430 EXII cannot be fired as a dumb slave, so far as I know. It can only be controlled using Canon's commander mode via the 580 or 7D or st-e2. It's a big frustration for Canon flashes, which frankly, are not really made to be user friendly so far as triggering options go. The Hensels likely have an optical slave built in, as many monolights seem to (Hensels among them).
So, you could use your 430 on camera and the Hensels off camera. Or, you could get a hotshoe adapter for the 430 that has a pc sync (I don't think the 430 has a pc sync... but could be wrong...) and then use a pc sync cord. Those are your cheapest options. Beyond that, you're getting separate triggers of some kind. |
