After recently paying a lot of money on a scanner repair that was a direct result of a firewire being plugged in wrong by a computer "tech" I have this question . If a firewire is plugged into a Leaf Aptus the wrong way how much damage will it cause to the back ? Is the Aptus designed like the 1ds and 1d mark II where it is a simple part change of the firewire port or does the entire back need to be replaced ? I am curious as to what Leaf has done to protect their digital backs against electrical damage from a firewire cable . I would also be curios as to the same questions for Phase One backs as well .
The Leaf Aptus has a short-circuit protection built in to the FW board and if you use the Leaf supplied cable with the L-shaped plug it'll be nearly impossible to plug it in the wrong way.
You are still very likely to damage the FW board in you Mac if you do that, though...
The Canon BTW use a mini FW socket that does not deliver any power to the camera (it is powered by it's own batteries) so it's irrelevant to the subject....
Hope this helps
