I have been reading these threads with interest as I too have been wanting a digital body to suit my lenses. I have decided that $1200 to $3000 is more than I want to pay for a decidedly old digital camera (R-D1 or M8) and I don't have the sort of money to need to look at an M9 or newer.
I want as large a sensor as I can get, under $1000. I don't give a fig for the autofocus as I'm going to be manual focusing anyway. I want a VF not just a rear screen.
It won't be for everyone, but I've gone for the Sony A3000. It's basically a NEX-3 turned into a pseudo-SLR out of the Sony parts bin. Low-spec fixed rear screen and EVF but the 20MP APS-C sensor out of the A58 (cheaper because it has no phase detection on board and therefore slower AF). You have to manually switch between EVF and rear screen - which works for me because I want to be able to ensure the screen is turned off.
One plus is you get a mode dial on the top deck - to make it look more SLR-like I suppose, but it also is a function you don't get in any NEX below the 6.
I have to live with only one control wheel (the multiswitch wheel on the back). Since the lenses have aperture control, and ISO is one touch away anyway, it's a compromise I can easily live with.
The largest problem, such as it is, is that there is only one programmable button and it's the bottom one on the back, so not easy to use. I've programmed MF assist magnification to it, but it's awkward to use. Again, given that the features I want are only available otherwise in a NEX 6 at 2 1/2 times the price, I can live with the compromise.
I suspect that for most at RFF the low-fidelity (apx 0.2MP) EVF and rear screens may be the real barrier.
I have decided that for by far the best sensor for the money (DxO mark scores it equal to the NEX 5/6 sensor and a little below the Nikon 3200 etc 24MP sensor) I can live with the poor viewfinders. The sensor in the A3000 performs better in DxO tests than the same sensor in the A58 - probably because it doesn't have to live behind a translucent mirror.
With kit lens this is going for around AUD$340 at present (around USD$300).
BTW it is starting to look like Sony are using a form of the Canon numbering system for the Alphas, where 1-digit numbers are best and 4-digit numbers are base model.
