When i put the the standard box diffuser on my Nikon sb-700 flash, the zoom head position does not follow my len s focal length even when the flash it set on TTL mode. Once the diffuser is taken off the zoom head position syncs with the len s focal length again. Any one knows why this is so? Is the TTL not suppose to work with a diffuser?
