Hi Troy,
Thanks!
I purchased the 580EXII from Photocontinental – they had it on special at $549 which was as good as the grey import price at the time. I built an arm that fastens to the tripod ring mounting foot of the 100mm F2.8 and used the OC-3 cord to mount the 580 on the arm, some 4 or 5 inches above the lens hooded 100mm.
I’ll try to take and post a ‘photo, or better still, show you the home-made set up at the next BIMBO meet!
Cheers
Dennis
