Take it for what it is...
A test with 4 different 50mm lenses all at 1.4 and 1000 ISO.
The first two with the Leica 50 Lux and 50 Noctolux on the Sony A7r.
I think these cameras and lenses all did a good job, although my preference is for the Zeiss on the D800, and the Noctolux on the Leica 240.
All Raw files brought in to LR5 and untouched.
Really, when you get down to it, I think ALL these cameras and lenses are great.
Enjoy, and take it for what it is.
Keep the fun real.
Most visible difference seems to be the different color renditions that result from the different LR camera profiles. Would be interesting to see the output if a ColorChecker profile was applied to each one.
Other than that I agree with you. They're all fine choices.
The A7r + Noctilux is a low-light monster. A bit lopsided to hold at first but it becomes almost comfortable after a while.
I totally agree with you, and certainly not That much to fret about.
