I studied the Olympus park (mainly omd-e5\10 and some lensens) and i also tried in some session the e5 by a friend that have it.

I really liked it, but... for me, for my idea of travel and shoot the digital reflex is ok. I got no problem with lens change so...

My real "doubt" is... okay, invest now on a FF and work on optics, or stay with APS-C and work on optics.
