• UPDATE



    The forum will be moving to a new domain in the near future (canonrumorsforum.com). I have turned off "read-only", but I will only leave the two forum nodes you see active for the time being.

    I don't know at this time how quickly the change will happen, but that will move at a good pace I am sure.

Why do I always get a CD in the box containing a lens from Canon? It's black and it says "EF lens" on it, and also "Ver. 4.1."

I've never opened one. And yet my lenses still work? :o ;D

I'd be curious to know what it is, and what if any value it adds. I register my gear at Canon's website so if there are needed "downloads" (even then I don't really understand what those are for) I assume I can do it that way.

Any insight is appreciated. (Yes, obviously I am aware I could open it up finally and check it out ... but I think out of some vague sense of preserving potential resale value, coupled with my not understanding the benefit, makes me think it's better to leave it in its packaging.)
