Jim, I had a NEX7 and shot it with various lenses including some of my Leica ones. I ended up mostly with the Sony Zeiss 24 1.8 as it was such as nice combination of AF and IQ. I now have a RX1 and have sold my NEX7. I am still keeping my 24 1.8 for now as I'm still very impressed with this lens. Tack sharp and beautiful rendering.
I do not have side by side comparisons as I sold the NEX7 prior to buying the RX1. From looking back at some of my recent pics, I won't say the NEX 7 with the 24 1.8 is inferior to the RX1 in anyway if you look purely at IQ shot at base or close to base ISO. Noise starts to creep in on my NEX7 even at ISO400 and probably hit my limit at ISO800 whereas I am not bothered by the noise on my RX1 until ISO3200. The colors on RX1 and NEX7 & 24/1.8 looked similar (RAW) but you can definitely push the files on the RX1 more than the NEX7. Both the RX1 and 24 1.8 have the Zeiss pop and contrast look to them. Dynamic range on the NEX7 was very good, certainly the best of APC sensors. If you don't need full frame, high ISO or a more compact setup, I would say the NEX7 with good glass is a better buy. For me, I wanted full frame and high ISO in a relatively compact setup which led me to the RX1.
I was really skeptical of the RX1 when it was announced. Up till December, I wasn't even interested in the camera or bothered looking at the reviews. But when an opportunity turned up and one was available, I decided to give it a try and am liking it so far except for possibly four caveats. 1. I still think its too expensive for what it is, especially considering that you most probably need to add the EVF. 2. battery performance sucks big time, but luckily you can buy cheap knockoffs for $10 a pop 3. I expected better barrel correctionfor carrying the Zeiss name. I need to add +12 to +14 barrel correction in LR4 on the RAW files and I'm effectively throwing away pixels. 4. video implementation was watered down compared to the A99, ie no mic volume control, no focus peaking in manual video mode, no histogram display in manual video mode. Again not important to many shooters but Sony really could have done better here.
Hope this helps.
