Years in the making, Apertus has released 25 beta developer kits for AXIOM–their open source digital cinema camera. This isn’t your point-and-shoot digital camera. The original proof of concept from 2013 had a Zynq processor (a Zedboard), a super 35 4K image sensor, and a Nikon F-Mount.
The device today is modular with several options. For example, there is an HDMI output module, but DisplayPort, 4K HDMI, and USB 3.0 options are in development. You can see several sample videos taken with the device, below.
The current device uses a Cmosis CMV12000 image module, although a Kodak KAC12040 and Cmosis CMV2000 module are in the works. You can find the complete specs online, but be aware that some of these specifications are forward-looking. On the other hand, the videos clearly show it is in a working state.
If you’ve been looking for an open source FPGA or microcontroller project to hook up with, this might be it. Like a lot of open source companies, they are trying to commercialize to keep the project healthy, but if you read their website, they seem to be committed to the open principles.
