[:|] Pardon my total ignorance but the only foreign language I know is alittle bit of Italian due to my ancestry! I'm sorry but I pretty much never use live view and as far as I knew there was only one liveview (regular) unless it kicks into face detection liveview mode. So I guess I don't reallyknow what I was using but the screen didn't black out at allbut it did error out a few times and could not focus on the line on the paper.

Also, as a side note, when I turned my camera on the other day with the Sigma attached it showed f/00! I had it turn it off and back on and then it was ok.
