Scott Torborg who is known for taking cameras apart recently showed how he took apart a Canon EOS-M to its most basic components and shared his process and findings. It is quite an interesting process and we learn a couple of interesting things.
I am not sure if anyone will want to follow this at home, but the instructions are certainly detailed enough for anyone willing to take the responsibility.
The camera is not easily disassembled and even removing the front board is not trivial. I guess this is done to fend off anyone who want to play with the internals of the camera.
The sensor is the same one used in the EOS 650D and you can see both the little vibrating part (the actuator) that removes dust from the sensor and the IR blocking film (AKA hot mirror). This is a pretty delicate filter, and it broke as Scott removed it, rendering his camera to an IR sensitive camera.
There you go, I guess the real challenge is putting it back together again.
