Why are some Personal Function numbers missing ?
Personal Functions in the EOS-1D that correspond with those in the EOS-1v (up to P.Fn-28) have corresponding numbers as well. This is for the convenience of users familiar with the EOS-1v. Some features that were Personal Functions for the EOS-1v have become Custom Functions for the EOS-1D. In other cases where a corresponding function is not available, the number has been dropped.
