Got rid of my Sony RX100 – will E-PM2 with kit lens address its shortcomings?

I’m in the market for a ‘compact’ camera with good low light performance and video, and I was initially attracted by all the hype around the Sony RX100. However, the more I used the RX100 the more the compromises Sony made by cramming such a (relatively) large sensor into such a small body started to annoy me. Notably:

- Very poor image stabilisation
- Very soft corners (and the softness starting some distance out from the corners)
- The lens is fast wide open but it stops down 3 stops by the time you’re at 100mm (full tele)

I’ve ended up selling the RX100 and looking at other premium compact options: Panasonic LX7, Canon G15, Olympus XZ-2, Pentax MX-1 – and I’m particularly interested in the Fuji X20 that’s just about to be released.

I’m not really interested in an interchangeable lens system – it just doesn't suit me having to swap lenses. But of course there’s no reason I can’t get an interchangeable lens system and just stick with the kit (or another) lens.

I had this in mind when I came across the E-PM2. What appeals of course is that it has the same sensor as the highly rated EM5, so is image quality and high ISO performance should be good. And in  terms of size and price in compares very well to the other premium compact cameras I was looking at.

I have a few questions though on how the E-PM2 with kit lens compares to an RX100:

- dpReview don’t have and studio shots with the E-PM2, but I did find some of over on the Imaging Resource Comparometer. It shows the E-PM2 comparing favourably to the RX100 even if I take into account it the 2 stops difference in aperture at its widest end if using the kit lens. However, I think the E-PM2 shots there are taken with a prime lens and not the kit lens (like dPreview), so I’m not sure how results would compare with the kit lens.

- Video: I’ve heard some say that you are better off with a Panasonic m43 for video with stabilisation in the lens rather than an Olympus with stabilisation in the body. Is this true? I know the E-PM2 only does 30p, but that’s fine by me. Other than that, any comments on the video quality? The RX100 had very good video.

- Is there a standard zoom lens I should get for the E-PM2 instead of the kit lens?

- I would hope the kit lens on the E-PM2 wouldn't have the degree of corner softness the RX100 had, but it’s difficult to know as neither dpReview or Imaging Resource have done any studio shots to test this so any comments would be appreciated.

- I think it goes without saying that the E-PM2 would have much better image stabilisation than the RX100.

Thank for any feedback.
