There are 2 major definitions of "analog": one in electronics and one in literature & science. Unfortunately, the term fails both when applied to film cameras.
There isn't any difference between the electronic and scientific version. Both denote something that changes continuous in time. (the literature interpretation as being "vaguely equivalent" is out of this context)
The problem is how it interpreted by those that have no electronics or scientific background.
