The Alt Cine folks have been posting on the cinepi boards for the last little bit that they are building some cameras around cinepi with some software tweaks/additions/add-ons.
Today, they announced them - all based around a super 16 Starvis sensor.
Looks like they can record raw up to 4Kp60 in 12-bit readout, 4Kp30 in 16-bit readout, and 1080p90 in 12-bit.
Media is cf express type b.
Interface is 4" touch screen.
"Eve" has a c mount and is the most affordable option, battery mount is swappable, they mentioned np-f or v-mount, though it seems like the mount is non-integrated so power will be by dc barrel only - sells for about 450-480 GBP and you need to BYO Raspberry Pi 5 (8GB)
"Elite 16" has similar specs to Eve, but a nicer/more robust body (which fits the Kondor Blue V-Raptor cage) with better I/O and has integrated v-mount as well as the DC barrel. It has a Micro 4/3 mount which may or may not be electronic depending on licensing - sells for about 950 GBP and includes Raspberry Pi 5
The footage looks pretty nice (with the caveat that they're still tweaking the output). Once they're a little further along, if things are looking good, I'll probably pick up the Eve. Could be a fun camera to use with my old Super 16 lenses. The price of the Elite 16 is, I think, a good reflection of the time and effort they put into it, but for me, the body size and cost are a bit more than I'd be excited to pay for a super 16 setup.
