Well, I don't _recommend_ them (alkalines), but they can be used, though they
are better in some applications than others of course.
In a camera like an OM-1 where the battery only provides power to the meter,
that's one thing -- if the battery is a little off,
you'll still get photos. We used the same 625A (alkaline) to check meters for
a full year and it still provided 1.5v under load.
Still, to be cautious, we tell people to replace them at least once a year if
they decide to use them in their OM-1/1n after
conversion. A silver oxide should provide accurate meter readings for several
years by comparison.
In a newer model like an OM-4 or 2s, or even "compacts" like the XA, that need
battery power to operate the mechanism, alkaline
batteries are best avoided except in emergencies (like if alkaline batteries
are all you can find at the only drug store open at
3a.m.). They should operate the camera for a little while, but I wouldn't
depend on them.
