For mirror lockup, using a mechanical cable on the lens, these are the steps, according to the manual:

1. After screwing a cable release firmly into the Mirror Lock-up Socket of the lens, the socket will elevate slightly and the camera will be ready for mirror lock-up operation.

2. Press the Cocking Lever as far as it will go. Step 2 may either follow or precede step 1.

3. Depress the Shutter Release Button and the mirror will rise, but the shutter will remain closed.

4. Press the plunger of the cable release and the shutter will operate.

Is there any advantage to purchasing the more expensive electronic cable? Are the steps outlined for the mechanical cable on the lens, basically the same for the electronic cable attached to the body?
Thanks,
You can't see what you're shooting since the mirror is up with the mechanical release. With the electronic release, you can since the mirror is down till you press the button. It's useful for studio work, especially portraiture.

Believe there are two versions of these that differ in their connectors: a 4-pin for the manual 645 models and RZ and a round connector for the 645AF. Sellers often confuse them.
