Hi all.

Im looking to move to full frame and have decided on the 6D.

I dont mind going second hand to save ~$500, but are there any common issues or problems with the 6D that i should keep an eye out for.
If there are a few things that are known to go wrong on them i may go new due to the fact that i have warranty.

BUT if there arent any issues is there anything i should look for to be on the safe side such as <5,000 actuations or anything else?

Cheers,
Luke
