I must admit that I have never updated the firmware in any of my canon bodies.
I never had an issue to resolve.
With the announcement of the update for the 5DIII, I am rethinking that decision.

When I review the fixes involved, I do not have any of those issues.
I only recall when I have update computer software and how unpleasant it can be and in some cases leaving me less functional than prior.

I really really don't want to mess with my 5DIII.

So what is the advice from the forum?

If I do decide what are the steps involved in the process?

Anyone had a bad firmware update experience?

Thank you.
