Same...focus issues and low light capability put me off plus the not so good screen. Thing is when Oly fix those things in the next version it will indeed be a very compelling camera. As it stands I think this will sell by the shed load!
I did have one on preorder a month or so ago, but eventually came to my senses. I do think I'll eventually get a M4/3rds camera but think I'll wait for a second generation Oly, or see what Panasonic or perhaps someone else comes out with. The concept is nice, but there are just a few too many shortcomings at this price range. My LX3 works nicely as my small camera for now.
The Pen has been available in Japan for a short while. I read a few reviews yesterday in some Japanese photo magazines, and they seemed rather positive. I thought about picking one up, and I plan to try one out this weekend.
I really liked the early Pen cameras, I may take a look at a few of those (one of the good things about Tokyo is it's plethora of used camera shops) this weekend as well.
I tried one out in Tokyo yesterday, and I wasn't overwhelmed. The Pen is supposed to be a compact camera with full-size camera features, but it is a little of neither. In real life it is not as small as you might think. In style it is similar to the Pens of old (which I also looked at), but was in fact noticeably larger.
The auto focus seemed adequate enough to me, no quicker or slower than most other point-and-shoots I've tried. Taking a picture wasn't SLR instant, but not that bad either.
All in all it seemed a nice enough camera, but not nice enough to justify the 100k yen starting price. For that money I would rather invest in an old Pen F and a few lenses and experience the genuine article rather than the re-invented one.
