Is this shutter acuations
I think canon is the only one who could tell on a 1diii, I would like to know mine as well. Some software will tell you the supposed actuations on some bodies, but may not be right. I know photoshop was wrong on my 1dsii (it only goes up to 58000 or something like that) Photome was right, and showed almost 270,000 when the shutter went, but canon replaced it and set the count to 0 but photome didn't change. It is apparently reading the counts on the mirror box and not the new shutter.
