What I say may be predijucial to olympus EM5 MK1 the 1st generation but reading online, I would give it a miss..
high potential of failure ( image stabalizer ,just days ago bns offering dead em5mk1 for $50 no charger or batttery
for parts unless you have other failures that this is really a piece of junk too expensive to repair/replace might as well buy one that is working). EM5 mk2 will be more expensive so that makes EM10 MK2 a better option considering features it comes with vs MK1. Of course if you like Fuji by all means.
I own a EM5mk1. Its been like 3 years already and I have no problem with this gem. Took many, many beautiful photographs with it and even use it for work. Many people say I take beautuful photographs but it's actually due to this camera. Will still be using it until my next upgrade.
