Well I scored a Pen F from the Olympus refurb sale. I've gotten a few refurb things from Olympus before, the only issue I've had was I had to return one of them and it took a loonnngggg time to get the refund.
The AF of my X70 was one of the reason I got the X-E3. The X70 is fine for a lot of what I tend to shoot when I'm out and about. But there are times when the single point AF is just not fast enough. I know the AF tracking of the X-E3 is better than that on the Pen F, but single point AF on m4/3 is really pretty darn quick. And it's rare that I don't know I'll need track/phase AF ahead of time and I have the E0M1.2 for that.
