We need more info.
Side by side as in both firing?
How are you triggering them?
Does this happen when you use your XTi?
2. IR trigger from 7D. I'm using the Nikon SG-3IR(http://www.bhphotovideo.com/images/largeimages/410445.jpg)
3. I just tried it with my xti and it only triggers the YN. Prolly that's why.

Im not familiar with then Yongnuo flash, but Im assuming its optically triggered?
if so, the preflash from the 7D (all Canon E-TTL IIs do) is tripping the optical slave sensor on the YN-467.
btw are you from 3si? its Macky...
Yes, the pre-flash triggers the YN. But when it achieves focus and I press the shutter and observe both flashes as they fire, I can see the YN firing first by a split second. If I look at the preview, the flashes fired together. See my next response below.
And yeah, this is Bruce.

+1 The preflash from the 7D is triggering the YN-467, set the 7D built in flash into manual mode.
Oh I got it! When in Manual, they both fire at the same time. But on ETTLII, the YN fires first by a split second. Both pictures look the same.
So YN is not IR triggered? Thanks everyone.
