Comments about Bogen Imaging Bogen - Manfrotto Flash Adapter, ISO Shoe to 1/4x20 Screw Adapter for Nikon (#3298):
This is just what the doctor ordered. The problem with the Nikon unit is the 1/4-20 tripod socket. I really needed a place to park the end of my SC-28. WIth the adapter, I can use a flash bracket and remove the flash for hand directed off-camera flash. Works really well with a flash bracket to get the flash off-center to reduce the possibility of red-eye.
