My work trips are more often than not quick overnight stops so no time to see anything other than the hotel and airport.

Other people I know are kinda talking about a tourist daytrip to Paris next year, so if that happens I'll probably stick around some extra days. Not sure I would want to move there. I last studied French some 20 years ago, and I wasn't any good then!
On the noct, the only reason I mentioned it is it is both fast and corrected for coma(?), which is particularly noticeable in #3 but also other shots to a lesser extent. In my experience so far with the MF Zeiss 50 makro, it isn't as bad as feared even with the 7D viewfinder. Once calibrated the focus assist also helps, but I could work on my speed...
