Hi all. I have an EP-3 that I am using after selling my M1 because I could not bond with it (I know it's crazy). In the meantime bought a Fuji E-X2 but same thing: outstanding IQ but I feel better with the Pen. Now I want to upgrade to something with the 16 mpx sensor so my doubt is M-10 or an EP-5? I read somewhere time ago that there was some issues with the EP-5, shutter shock if I remember well. My question is: is there any known issues with the EP-5? Will the improvements from an EP-3 be important? What about the M-10? Thanks to all.
