Thanks Tim, I'm evaluating a Demo M240 right now and these are helpful (even though I do not shoot many landscapes).
It confirms what I found in a controlled "quasi-scientific" sort of test using all constant elements. The M240 exhibits some IR contamination (somewhere between the M8 and M9 as far as I can determine so far) ... see attached test with M240 in Tungsten light with, and without, an IR filter on the lens). In discussions on the LUF I have come to understand why a weaker IR filter was used on the M240. However, it is there.
It is also apparent in your real world images in the sky, (see crops from your samples of the M240 sky, which reveals the magenta cast when placed next to the A7R sky, which is relatively neutral. This may also account for the slightly more vibrant fall colors (only confirmed IF the shot was done with and without an IR filter) ... maybe okay for landscapes, perhaps not so good for other applications.
I agree with Taylor that the A7R has been over sharpened ... someone suggested rather than LR RC5.3, it may be better to use the latest DNG converter and then process A7R RAW files in LR4.4. Since my computer is older, I can't install LR5, so I used the DNG converter for the A7R files I shot, and can say I didn't witness such brutal sharpening artifacts. Not sure that proves anything ... it would require A RAW file be processed both ways to really tell.
