Ok all--I did two rounds of testing. I found some issues with the first round, and I now tested the 50.1.5 Simera e-mount at 3 distances. I have to go back on my statement above. And massive props to Thypoch. I don't know why they aren't tell people their lenses have been tweaked for Sony, or at least the 50mm. I am now very curious if the 28mm and 35mm has been tweaked for Sony sensors, or at least the cinema versions.
The Thypoch-C 50/1.5 has been optically tweaked to work better for Sony sensors.
My finds are that, the midzone is slightly better at near distance on a modded a7rII with an e-mount lens, but the corners are worse at near (3-4 feet), mid (12 feet) and infinite (200+ feet). The modded camera here is an a7rII (42mp), the stock an A7cii (33mp). So the crops you arelooking at for the modded crops are higher magnification than the Stock. Just something to keep in mind too, at all distances and apertures, the lens is re-focused on the center.
So, the corners are worse on the modded sensor at all distances, indicating the e-mount version is indeed better for e-mount, and has been tweaked from the m-mount copy. Bastian's crops show the Simera M 50/1.4 performing much worse on a Stock a7r2 and better on m-mount.
Another interesting observation, this e-mount 50mm plays very well on both sensors, unlike the m-mount. I personally would not hesitate to use it on both unless I was worried about extreme corner sharpness--the e-mount Simera is great on stock Sony at f4, but needs to be at 5.6 on the mod. Beyond that, it's a 50mm that works very well on both sensors, with some slight advantage on the stock Sony overall. I am not seeing quite the color richness and micro-contrast of the 50 Lux, but honestly, the Simera 50 is pretty impressive and better in many other areas.
