I’ve just picked up a SB600 having used a 400 for a while and deciding that some of the futures of it’s big brother would be handy.

Here’s my confusion, can you point out where I’ve missed the point? As I understand it when fitted with an appropriate lens, the camera reports focal length to the flash. The flash then uses this info to set the zoom, if the flash is in auto zoom mode. Now here’s my confusion, the camera a D90 is a crop sensor camera, so the zoom set is in effect wrong, is that right?

I believe that the big daddy the SB900 understands what camera is being used and corrects for this. Why doesn’t the camera, which knows it’s a crop camera, report the appropriate focal length to the flash i.e. corrected for crop factor. It seems daft to put this responsibility onto the flash?

Have I missed something.
