Dude... I do too....
I totally work with a group of trained assassin photographers from the future. I've traveled back in time because it's getting close to the time of the release of the camera that changed life as we know it.
It began simple, the 5dMKIII was released just as you are saying. People used it and fell in love. They sold all of their current gear and invested all of the money into the 5DMKIII. This was easy, since with the 5dMKIII came the first ever Canon Multi Lens, the only lens that could adapt itself to every use and possible situation, from f/.001 to f/7000 depending on available light, and it would transform from a 1mm lens to 5000mm lens with the flick of a switch.
However, the lens testing was not completed thoroughly enough, as mating this intelligent lens with the Canon 5dMKIII's quad Digic VI processors allowed the lens and camera to combine into one semi-living, self-aware, sentient being.
The lens and camera combo started to absorb the users, until just a few of us were left. We were the ones who were happy with our 7d's and didn't early-adopt the 5dMKIII. Unfortunately, we were pushed to the caves in order to survive.
After some time, we managed to get one of the 5dMKIII creatures to absorb a 7d that was on a wired remote. Using the wired remote, we were able to travel through time by setting a multiple exposure sequence into the 5dMKIII's circuitry.
A small group of us managed to come back to warn you... don't buy into the 5dMKIII ... .it'll only result in the destruction of the world as you know it.... It'll be fine at first, but starting with Firmware Update 1.2.93, things will change.
