I have not tried the IV yet. But I found this comparison by Nick Frank: http://www.iso72.de/metabones-sony-nex-smart-adapter-mark-iv-vs-mark-iii-sealed-comparsionreview/

It seems that the new features are mostly a wider opening and a different coating to reduce reflections. But it seems as if metabones did not really solve the issue with image degradation with the TS-Es (http://www.luminous-landscape.com/forum/index.php?topic=85249.0). According to Nicks tests with the TS-E 24 the flocked metabones III shows better performance than the IV with the new coating. So no good news. The IV might be the better option if you have none yet - because it has a wider opening. That will probably help if you want to flock it (with the metabones III I still get somes vignetting with full shift because of the flocking material gets into the light path). But if you already have a metabones III it seems not worth an upgrade.
