Get a 5D III, fill it with honey, set it next to the 5DII The Ants will upgrade.
I don't know which joke to choose in this post, they're all so freaking hilarious!
Kudos to everybody!!
BTW where do you keep your camera, how many ants do you think are inside and still I don't understand how they manage to get inside if you kept the battery door closed.
So far my joke has earned me 2 smites, and 0 applause, so the system continues to work well!
On a more serious note, Ants will go in things to explore, but will generally leave if there is no food to be found. So unless there is food inside the camera, they should just leave. I think I might place the camera outside in the sun to encourage the process. And maybe remove a body panel to ease the path out.
