I shoot a 4-year-old 5D2 with an 8-year-old original 5D as backup (but have never had a failure of the 5D2, so have never had to use it.) Now I feel like it's time to demote each of those and get a new camera. I looked at the 6D. I looked at the 70D. Of course I drooled over the 1DX and the 5D3. But in the end, this past week I bought ANOTHER 5D2 used at B&H!
