Just a little change for my SD9 Power system,
you can diy yourself , no need CR 123 A Battery again
please comment
I can't help thinking that there's got to be some good reason not
to do this. I just can't think of what it is.
Sigma and Fuji (with their S2) make some pretty heavy modifications
to the film cameras (Sigma SA-9 and Nikon N80) that they use. This
seems like such a trivial morification. Nikon and Canon managed to
do a pretty good job of it in their D100 and D60.
Sigma isn't stupid. They have to know how the whole "double
battery" thing affects people's perception of the camera. They've
seen Fuji get slammed by the press repeatedly over the last couple
of years for needing two batteries. Adding a single wire is such a
low cost way around this problem that there must be a catch.
Silly theories: the lithium battery runs the motors and solenoids
part of the camera, so the separate batteries allow Sigma to
isolate the sensitive digital electronics from back EMF from the
electromechanical components. Or the rechargable battery pack
couldn't deliver sufficient power to reliably operate both the
digital electronics and the electromechanical components
simultaneously, so they opted to leave in the small lithium, rather
than making the AA battery pack bigger.

). And I don't want to touch the body and what I consider to be an advantage is that this setup is so simple that I can pull it out whenever and wherever I am and want to use CRs or reinsert it if I have no CRs availible or don't want to use them (with some fideling to find the hole)
