Does anyone know how the Voigtländer 75mm F1.9 Ultron in VM-Mount performs on the Sony sensor stack?
It‘s such a nice, small lens that spaces reasonably well between 35 and 135mm…
I would suspect with high likelihood that it is fine - two things are going for it: the focal length and the lens speed. I have used rangefinder M lenses a lot on my Sony A7R (unmodified) before using digital M. I have only seen issue with M lenses below 50 mm FL. And then especially if they were f/2.8 or slower - faster lenses were fine due to the larger inner lens diameter. The 75/1.9 has both positives to work with thicker sensor stack.

I think it works very well. I have one and have used it on my A7C quite happily, mostly wide open for close range and at f5.6 for corner-to-corner sharp infinity shots. Some samples:

Adding a few ones (M-lenses performing noticeably better on Leica) I tested both on Leica M and Sony E-mount cameras. The lenses below exhibit purple vignetting and some corner blur on Sony E-mount sensors when used with M/E adapter.
Voigtlander 12/5.6 II
Voigtlander 21/1.8
Voigtlander 25/4.0 Snapshot Skopar
Leica 35/2.0 ASPH Version I (stay away from adapting to Sony - doesn't even focus sharp throughout the frame at f/8 and exhibits focus unevenness).

Adding the CV 35/2 Ultron as bad on stock Sony but great on Leica.
The CV 35/1.7 is pretty ok on a stock Sony and great on a Leica.

For me, the 35mm f/1.7 Ultron is still one of the best wide-aperture 35mm lenses for the M mount today. It's sharp, has beautiful bokeh, and a close focusing distance of under 0.7m – just an all-around fantastic lens that doesn’t need to hide from any others. Especially not from the 35mm ASPH Summilux versions. And definitely not when you can get it in like-new condition with hood for around 400 euros.

One cool thing too about the 35/1.7–offers full coverage on a GFX. At least at shorter distances. I never checked at further than a 15 or so feet. Lots of vignetting, but no hard vignetting.
If the 35 Lux ASPH and 35/1.7 were the same price, which would you prefer?

Yes, it really is impressive what the CV 35mm f/1.7 is still capable of – even on the GFX.
If price weren’t a factor, I’d honestly love to mount the current Summilux on my M. The silver design just looks incredible on a silver M, and wide open it's slightly sharper than the Ultron, with more pleasant handling. But that’s about it. In terms of bokeh, the CV is noticeably smoother and more pleasing to my eyes. That’s where the Summilux can’t quite keep up.
If the Ultron came in a simple barrel design – like the CV 35mm f/1.5 or the Summilux – it would be a dream. But I got a great deal on the 40mm f/1.2 last year, and since then, it’s become my daily driver and new favorite lens (though the new Apo Ultron is a whole lot of fun too).
40mm is just such a lovely focal length – even if it only takes a tiny crop from a 35mm lens to get there.
