I am contemplating buying the 5D in the near future, after reading many reviews from owners, most of which are good, I have noticed a couple mention contamination of the sensor from oil possibly from the shutter.
Has anyone on POTN (5D owners) experienced this at all, so far this is the only thing that has put me off?
I take much care of my current 350D and 30D and have not had to have the sensors cleaned yet, its not something I would attempt at this stage, I am therefore a little concerned about this possible contamination problem. Can anyone here convince me its not a problem?
