There are other options toshiba TC358840 Camera Serial Interface Converter Chipset (4K HDMI to MIPI CSI -2) https://toshiba.semicon-storage.com/content/dam/toshiba-ss/ncsa/en_us/docs/product-brief/assp/14A04_TC358840_ProdBrief.pdf
That chip could be used to feed the video signal from a DSLR into a Raspberry Pi. Not sure why you'd want to do this.
This is their 720p...
Looks like they skip 4 and leave 4.
FYI, in 720p50/60, your Canon DSLR records one line and skips 4 (5x3 column binning / line skipping).
Exceptions:
- 5D3 (with full 5x3 binning, rather than line skipping)
- crop_rec with custom binning factors (3x3, 1x3 etc)
I would ask them why, but its so unreliable at the moment anyways, exposure issues, dcraw issues with white balance, no way to control shutter speed by simpl switches.
It needs a lot of work, and considering that it was started in 2015, i dont have high hopes.
I wonder how 2x binning looks like and whats the max res at 24fps but still , controlling exposure is tricky, there is gain instead of iso and its controlled by command line so yo ucant change stuff mid recording.
Well, yes. The question was whether the RPi can capture raw images. There is a proof of concept for that, and a rather good one in my opinion. Yes, it's not polished for serious use, but it's functional, and - for the intended audience of RPi, i.e. developers, hardware tinkerers, tech students - it's probably enough to start the ball rolling.
To repeat this important point:
Not for replacing DSLR cameras
BTW, the image you are looking at was taken with the *previous* generation of RPi cameras. Compared to that, the newly announced camera is a noticeable improvement, in my opinion (but don't forget I'm terrible at pixel peeping).
https://twitter.com/hashtag/ShotOnRaspberryPiAnd you are no longer stuck with the default optics; you can use any other C/CS-mount lenses (heck, there were EOS M users adapting such lenses for filming), or - with adapters - pretty much any DSLR lenses.
I can only imagine this is going to lead to some incredible experiments.
Yep.
I wonder how it compares with something like
OpenMV H7plus (2592x1944 15fps, 1080p30, 720p60, 3.6x2.7mm active area, M12 mount) for real-time machine vision applications (visual servoing). In particular, I happen to be looking for a low-cost vision platform for CNC machining, where I'd like to get about 0.01mm positioning accuracy, or even micron levels if possible (with subpixel processing, of course), but the machine is relatively slow, so 3-4K resolution at 10-15 FPS, with optional cropping or pixel-binning for a higher frame rate, might be adequate. A "classic" 640x480 industrial camera is not going to do the trick. Are there other alternatives in this price range?
I'd get them both (RPi cam and OpenMV) for a comparison, but my budget is a little tight atm.
I could also consider an EOS M, but...
1) Good luck running computer vision algorithms on its general-purpose CPU (as Canon's image processing hardware is a big mystery even for us)
2) Exchanging the result with motor controllers or other hardware, is also tricky. UART to Arduino-like? USB to RPi? In any case, a second microcontroller board is needed.
Or, I could offload the processing to a RPi Zero, via USB, but I expect very large lags and very low resolution; maybe OK for a webcam, but not practical for visual servoing.
Magic Lantern port? 
If this camera proves interesting enough, it might happen sooner or later. Don't look at me, but at the target audience of RPi
Edit: some arguments against the RPi cam:
