a computer cdrom cable to a audio card works..
you might need to cut off a section to fit.
Telephone cable works good.
You could use something nicer..
buttons are less than a buck a piece.
For something easy to play with.. just get any old wire, strip the
ends..
touch pin 1 and 2 and watch the camera focus lock.
Hopefully, you'll get inspired and realize it's not so hard to make
your own.
I know there's a remote shutter release available for the D7Hi, but
somehow I'm missing it when I search the Minolta site and the B&H
Photo site. Can someone tell me a catalog number and/or a place to
buy this remote release? Thanks - Bill Hansen
