Pentax 645 25mm lenses differences

I know there are various threads about the DA and DFA lenses, but I was wondering if anyone knows definitely if there are any differences, apart from hood and 30gms weight (which I presume is due to the hood)?
Has anyone been able to actually see the two lenses side by side and compare?

Thanks

To add to my original post, a photograph of the DFA lens I printed out from the Home - Vanbar Imaging website, and a DA lens I printed from the Home - PENTAX Photo site are identical in scale, and the hoods are identical in scale also, the only difference I can see being the letters DA and DFA lettering on the silver ring.

I asked this exact same question about a month ago and didn't get any solid answers. Nobody seems to know for sure, but hopefully some answers will come. I have the D FA 25mm.

On looking at the hood further there is a difference, with the DFA flaring wider at something close to a 90 degree angle and the DA at about a 45 degree angle.

I wonder if hoodshape CAN be of any effective flare difference, since with the D-FA, i haven't so far be in situation to get some even in heavy backlight situation .
