The em5ii looks like a nice addition to my m4/3 gear but I'm wondering how they are holding up to general use now that the model has been out for a while. I ask because my EM1 is currently being serviced a second time for the rear dial problem. It is the only camera that has ever required service, despite the excellent care I have taken of it, and I use cameras quite extensively. I cannot have a camera that I can't depend on. Searches here and elsewhere have not yielded any widespread issues such as the em1 rear dial problem, but I would be interested if any m4/3 veterans have had any experiences that bear mentioning along the lines of reliability. Thanks!
