No direct news about the hoped for 40D announcement next week but I did turn up a couple of terms we might be seeing on all new Japanese digital cameras, namely "ISO standard output sensitivity (SOS)" and "ISO recommended exposure index (REI)".
It seems as though we might occasionally see terms like ISO 100 (REI) or ISO 100 (SOS) in a camera's documentation but, mercifully, there shouldn't be room for anything other than plain old ISO on the camera. That said, will we really care as we set an ISO number on our cameras?
I believe the point of this is to clarify (!) the fact that ISO speeds on digital cameras are not really the same animal as ISO speeds of film and are essentially manufacturer defined.
The original post which drew my attention to this is here
and the CIPA document defining all this may be found here
Apparently those lucky enough to own an EOS-1D Mark III can already find references to these terms in the manual.
Veering slightly off the topic of this thread, whatever happened to the much rumoured EOS 5D Mark II?
