Canon 600 ex-rt Speedlite & Remote Zoom

I'd assume 50mm, but why does it matter (as you'll be setting it and leaving it to suit the conditions / modifier)?
 
That's what I thought you were getting at.

Just step back and think, the zoom to match your FL is only useful where the flash is mounted on the camera pointed forwards. So that the flash angle of cover matches the angle of view of the lens.

Or as we'd call it, exceedingly rarely for most 'photographers'. As soon as we tilt the flash at the ceiling, the auto zoom switches off (the camera has no way of knowing how high the ceiling is), if we move the flash off camera, the flash has no idea how far away from the subject it is.

But we still zoom the flash for other reasons, wide to fill a soft box, or to match a brolly, narrow to create an interesting pool of light etc.

So while you're placing your flash off camera, you'll zoom it for it's purpose, but not to match the FL which would be pointless.
 
Phil. Completely agree with what you're saying.... however coming from Yongnuo RC622 triggers, which allow the remote zooming of a Canon 580exII flash... it feels like a backwards step.

I know for fact that I will take the flash off-camera and get an assistant / VALS / best man etc to hold it, and then remember "oh crap, cant adjust the zoom on this without physically doing it on the flash". Depending on the situation this will either be an issue or not. But knowing what mm zoom the flash defaults to would be useful to know - do you happen to know ?

Thanks
 
Are you sure this doesn't work?
I'm sitting here with a 6D, Yongnuo RC622 triggers and a 600EX-RT flash and I can remotely set the zoom.

It won't change automatically as you zoom the lens. As Phil said the flash has no idea it is away from the subject, but you can manually set it via the flash settings in camera and the flash will adjust remotely.

I figured you'd be able to do it via the 622's, but I don't have one to try. I'm guessing the 600's don't support it when you're using one as a master (which is why the specs would say it's not supported). All the flashes I own default to 50mm when you tilt them or move them off camera IIRC, but it doesn't really matter.

But I can't see the point in a 600ex rt, I can see the point in 2 of them, or at least one with an st e3.

I think anyone who already had 622's is as well off buying older and/or cheaper flash guns. As all the important stuff is already paid for.
