It's fantastic! If you get a chance, do yourself a favor and try it. It's a great, lightweight camera with all the features of the big boys in a small package. My EM5 and me are not parting ways any time soon.
Took these today with my Pany 7-14mm (14 - 28mm equiv. APS sensor) f/4 at Embarcadero in San Francisco - This is a rectilinear wide angle and though it may not have much history behind it yet, I think it's gonna become cult.
