This is a great question and there is no easy answer.
Before I got into MF, I had the same problem, what to do when I didn't want to carry a big rig like the Canon 1D4 or 5D2 along with the fairly large lenses. Image quality was important. So I moved from the NEX7 to the Fuji X100 and then the M9 and the M240 with the usual lenses. None of them did it for me, although at the time these were alternatives to 35mm DSLRs and not MF.
Finally the Sony A7R, IMHO the much 'bigger' brother of the NEX7 and so much better too. Less than a third the price of the M240 with a lot more to offer.
I've tried every lens I own on the A7R, the Leicas, Zeiss, Canon and even the Nikon 14-24 (I don't own any Nikon body but the lens is simply out of this world) via various adapters. I love the incredible detail in the files, especially with Sony's own 55 1.8 lens which is super sharp.
My favorite 'small size' package is the A7R with the 35mm, can fit into a small bag, very unobtrusive and quick focusing. You can put just about any lens on it, which is great.
The down side is the relative lack of native really, really sharp, AF lenses. Hopefully that will be amended in the future.
One thing I've found is that with third party lenses like the Canon with adapter, although you have AF, you really need to use live view to confirm focus because the resolution is so high that even the slightest error is magnified. Which means that you cannot use those lenses in a 'casual' shooting mode. For landscape use though it would not matter since one would take a slow, deliberate approach.
I now find I am carrying the A7R almost everywhere I go, it is small enough that you can even take it to a formal event like a wedding (in a small bag) without standing out.
And if you have a good smartphone it simply complements the Sony for the times when you really need 'small'.

I think the 645z has the option of saving files in either PEF or DNG format right in the camera. The former results in an average file size of over 70MB while the latter is less, around 55 MB or so depending upon the ISO used.
The second time you have the option to convert is when you import from your SD card, either directly into C1 or LR or Aperture. The program will ask you if you want to import as it is or convert it to DNG (I can't remember if Aperture offers it or you have to select it somewhere else). C1 as far as I know does not read PEF files directly so you have to convert them. For me it is not a favorite anyway. I have all three programs and have basically moved my entire library to LR now.
The other thing to remember in this debate is that AFAIK there is no way to convert a DNG back to PEF, so if you want to submit that once-in-a-lifetime shot to the BBC you are out of luck since they want only the 'original RAW' image and not a converted DNG whether done in or out of the camera.
