His repository is https://gitlab.com/zephray/sitina1. The hardware list seems somewhat incomplete, e.g., missing the metal ring and connector for the lens mount and pcbs.
with the use of shims, BMD cameras can switch out their mount from EF, PL, or B4 options. so it could be designed with this style in mind, and even make a link to BMD's site to purchase their kit of shims
Aye, a universal mount is possible if you have a custom housing for each mount type to match the backplane. Using BMD equipment might run afoul of patents... I don't know enough about the legal end of equipment manufacturing to say.
But it would still require custom mounts for each lens type... which is 100% doable.
I wonder how difficult it would be to do this with something like an old A7RII - there seems to be a good amount of older Sony A-series cameras with some kind of display or motherboard issues on ebay, but otherwise perfectly functional sensors
I have been passively looking at doing something like you are suggesting, but then also turning it into more of a video camera. My main motivation is that it seems pretty much impossible to get a off the shelf sensor that has DPAF.
One big hurdle getting the datasheet for the sensors - they are usually quite quirky and even if you get the datasheet and all documentation you will still need support from the manufacturer to get everything working reliably.
A HN reader would expound on why building you own camera is a waste of time, and anyway it should be written in Rust, and should have used a RISC-V or Mill processor, then gone back to reading HN.
I saw that as well. Can't tell if SafariBob is trolling or if he usually does afternoon lego projects with home built pick and place machines, reflow ovens, FPGAs, custom flex PCBs, C++ and verilog... But if he does I am deeply interested.
Someone linked the GitHub. That should have the PCB grbr files; maybe you can get them made yourself and just buy the discrete/processor components from DigiKey.
Also, DigiKey red makes PCBs.
On a full sized interchangeable lens camera, I’d give up having a screen completely before giving up the viewfinder. It depends on what and how you shoot, of course, but trying to shoot sports or live music without a viewfinder would be horrible.
