I'm usually really big on needing a viewfinder. I decided to give the Ricoh a whirl despite it not having one. If I like it enough to keep it, I'll probably find a 28mm optical to throw on the hotshoe.
When I got into m4/3 I started with an E-PM1 and made my way to the E-M10, E-M5, & E-M1. But to my surprise I've found I really prefer the Rangefinder style bodies and actually rarely use the EVF. I'm extremely right eye dominate really like seeing the whole scene to frame the shot. But the stuff I shoot for fun with m4/3 and the X70 is completely different than my event work where a viewfinder is pretty much a requirement.
