Here is my end result. I think I found a new hobby. Lego take my money. My first lego build. I also bought a starwars Mos Eisley Lego set as well. That one, I'll save for another day.
it's quite a lens with a very unique look. At f/2.5 infinity on the M9 even distant details are very crisp. Colors are very rich.
The lens was somewhat maligned in the early days, with assertions that the bigger Elmarit-M was better and the build was not up to snuff. I find neither to be the case.
I often had this lens on my stock A7 and the 28cron on the M9 for a two body shoot.
A very close look shows the stock body very slightly muddier, but pretty nice. This was the same body I sent to Kolarivision.
The lens was introduced in 2007, two years before the M9, so it's unclear if it was "designed for digital". The M8 of the era has the thinnest CG ever on any digital camera, which perhaps also explains why M8 images are so striking even today.

First two with the WATE (f/5.6 and f/4), third with the 35 Lux FLE f/4 and the last WATE f/5.6. More testing is needed but there is an improvement with both lenses.
