I don't know about the SB-900 but on the SB-800, if you stick the diffuser on - you will never get the flash head to zoom to 35mm....

I am pretty sure that the GN number was measured without the diffuser in place - especially if it stated at 35mm FX because the only way to zoom the head is to remove the diffuser.

According to the flashmeter manual, it must be use with the diffuser in place.

We were talking about the sekonic dome diffuser for incidence light mesurement, not the flash diffuser !
