Release cable MC-30 build by Avi

DISCLAIMER – Important!

I read some newsgroups posts and saw some sites suggesting how to build your own switch housing. Some advised to use one switch to activate both the AF and Shutter release simultaneously and some
suggested to use 2 switches, one for each function to be activated one after the other. There are some interesting posts of making a DIY radio remote, but for now I’ve decided to concentrate on manual release.
Eventually I decided to save the trouble of trying to construct my own switch housing and to use a Nikon one that will simulate the F100 operation, meaning short push to activate the meter and AF and longer one to release the shutter.
I found an old and cheap MC-12A cable and altered it to fit to F100.

Well, with this cable I ended this little project and I’m ready for my next one. I hope you’ll find my page clear to understand and hope you’ll benefit from it.

Have a nice and successful photography experience.
