I've had my MK I for about 1-1/2 years now, it is the wife's camera, and it gets used fairly often.
The issue of the poor viewfinder was not really well addressed, buying a optional viewfinder for $200 or $300 is not a option for us.
The lack of close focusing seems to have been improved.
The poor lens cover has not been improved. We bought a third party adapter that works well.
No touch screen, or dual pixel AF, both of which I would make use of. The Wi-Fi would get used.
I managed to score on a rebate deal with my MK I unit, paying about $100 after all the rebates, I don't expect to ever see a deal like that again.
