I think all the white ones are missing the flash diffuser. that true supplier one looks just like the others but more money.
I'm wondering if there's a technical reason why the diffuser is not on the white backs? The black backs that IRESQ, et al., sell have the diffuser and the little plastic insulating strip on the side, whereas the white does not. I wonder if the white plate is truly OEM without the diffuser? Maybe the diffuser coupled with the white back washes out the picture with the flash, whereas without a diffuser the flash is more direct?
