Before I got my 5D2, I used to get the 99 lens communication error on my Rebel with my nifty-fifty, but ONLY with that lens. I thought it was the camera even so. After I got the 5D2 I still got it with the 50mm so I figured it was the lens but now I also get it with my fish-eye. Has anyone else experienced this problem with the 5D2?

I did research a small bit using google. In the rare instance, that you've not tried that yet, heres what i found:
One user found they had loose screws on their lens and tightened them up --> this fixed their error.
Another user found upon shipping it to canon that it was an IS system error. I assume this was not your problem considering the lens. Also the user estimated a repair cost of $300. Perhaps, attend a local club or photo store and try out one of their lens of the same kind? Doesn't make sense to repair a 50 1.8 given its purchase price.
One customer managed to talk to someone at canon and get their's fixed free.
One user noticed a dent in their point of contact. Try a thorough cleaning of lens contacts. I would suggest a low residue after evaporation alcohol or an eraser clean, but follow that up with a thorough debris removal to avoid any of those nasty parts from touching potentially approaching the innards of your camera body. alternatively, get them professionally cleaned. This won't guarantee a fix, but it will be another cross on the list.
One user suggested a firmware update. While this is a very unlikely fix, its recommended either way so - if you haven't yet...
One user was able to use the lens only in manual mode. This may be worth a shot. Someone sugggested taping specific points of contact with electrical tape - but they mentioned a risk of "losing tape in camera body"

I hope some of this helps...
thanks for all that, I was wondering if I canon would fix it for free since I just got it. I want to borrow a lens from someone locally just to make sure first, I figure 3 lenses is a pretty good test set.
I think a third lens should give good, more conclusive, indication.
From what i understand, Canon gives you a 1 year warranty from purchase. To be safe, I'ld make sure to register the product if you haven't yet before giving them a call. In the worst case scenario, its a camera issue and i think the fixit route would be the same as with the lens.
