The concept of multi-mount usage is coming, in fact it's already big in hybrid cinema. Nick Salazar convinced DZO (parent company of Thypoch brand) to focus on making the C series of the Simeras in M-mount, which after giving it considerable thought, they did. When you say 'performs well', it seems fair to ask you to elaborate on what you are actually looking for.
I have/use one of the 75mm Simeras, the 16-blade 75/1.4 stills Simera (exact same optics as the C), and I'd have no qualms whatsoever using it on any Sony a7 series camera, same as the other Simeras. If you need perfection, I don't know what to say. Maybe keep looking!
I have used the VM 75/1.5 and have seen no 'midfield curvature' of note, nor any optical slump, using a Sony a7r but I am more interested in final image quality than aberration perfection. For a lot of review commentary, you have to be aware of each person's particular susceptibilities for low count peccadillos. Different priorities apply, often heavily. It's often not easy.
Whilst in the dark about what 'performs well' entails, here are a couple of VM images shot on Sony's a7rI. It's a very sweet lens. Maybe they will help assuage any residual doubts, for others if not yourself. People are fussier than me, so that's my bias, lol. The Simera is a stronger lens wide open and the 16-blade iris shapes backgrounds beautifully, it's warmer and better for skin; and it has fabulous color, which is why it displaced the more dreamy CV unit in my keep. More of mine from that one in the dedicated thread here:
I don't think you can go wrong, but standards vary, often alarmingly.
Thank you, Philip, I've been seeing your 75mm shots with the thypoch and it's made me want to try one but I thought I remembered you mentioning have a modified Sony sensor, which Im reluctant to do still having only one body.
Will double check how the cheaper 75mm hold up for portraits compared to the Zony 55mmf1.8. I think the viltrox air punched in will be okay for walkabout purposes, so mainly wanted the 75mm nokton/simera for people shots with a bit more flexibility than an 85mm. The nokton VM version's size is attractive but so is the render on the simera.
