No argument there, Nathan--the Fujis do an amazing job in low light.  I'm
just pointing out a way to extend the M8's low light abilities. My E-M5 is
a little too laggy to be a real decisive-moment camera.  I often prefer RF
focusing and direct optical viewing in low light situations. If I can get
it with a little computer-geek sleight of hand, why not?  The jury is still
out on whether the con side is worth it--i.e, the buffer limitations and
the fact that you have to turn off battery save to avoid losing the RAW
setting.  But so far, it looks promising. And it's cheaper than blowing $7
or $8K for an M240 or an MM.
