Roger Cicala in the recovery of a rental for almost a brand new Canon 5D Mark III camera, which has a loose screw crash sound. After some consideration, he decided to do it yourself disassemble remove the screws, so we are able to see them all.
open the back cover of the 5D III, the immediately be able to see only one cable to connect it with the 5D II: back cover between the camera board. The back cover with the motherboard circuit using black glial plastic cover to protect the internal parts (and possibly play the electric shielding effect). Roger said to have never seen a similar treatment in other inside the camera. This is a very gratifying, and may also explain why the loose screws no further damage inside the camera.
motherboard circuit design there are also some changes: all of the cable is very short, direct connection to the place you need to connect to and fro long cable. In addition, there are some places to use wiring harness (upper left) instead of cable. Overall, the new camera internal circuit design better, but more insulation.
front of the camera circuit also simple and organized appropriately. There is no long wire line to firmly tie together, positioning and plastic hook. Roger said that this approach is not common.
show a little detail on the 5D III design improvements: screw the battery snaps very easy to replace. In other cameras (including the 5D II), to replace the battery mount will need to machine the “dismemberment” 5D III only need a few minutes easy to complete.(This article Source: New Photography)
