Besides m4/3, what other system do you own?

I shoot canon full frame in addition to m43. I'm currently happy with both. M43 works well for long hikes, travel, social, street, or toss in bag mode. FF is for events, DOF control, high ISO, and some deliberate, tripod work.  M43 works fine for tripod based work. Live bulb appears to be a huge advantage!  Diffraction at f8 and base ISO at 200 does make it a bit harder for long exposures.

It would be nice if Oly made an EM5-E with a base ISO of 50 or 100 and emphasis on detail and DR At base ISO. Not complaining about what we have, but it would be a nice addition and would probably grab a lot of landscape photogs from other systems.
