Raw video when (probably) connected to an external SSD. Nuff said. This thing is insane... I expect it to find a nice audience, especially for video productions that can't afford an Arri Alexa. Weddings, advertising, TV productions. Content creators in general. Heck, it's probably so cheap (and certainly small enough) they may replace the Blackmagic cameras in big Hollywood productions.
"The SIGMA fp’s Cine mode comes with a variety of special functions that are comparable to those of professional cinema cameras. From shutter angle display and waveform display for exposure and color information, to zebra patterning, it comes with the functions and screen displays that can be used in the same way as with conventional cinema equipment.”
Jesus. Sigma also offers a PL mount adapter. They know exactly who this camera is for. It's the first time I truly understand why Sigma is even bothering creating cameras. Panasonic should be worried. Looking at the market, if given the choice between the Nikon Z6, Panasonic S1 or a Sony a7, my choice would probably be the Sigma (if there isn't any deal breaker). And that's despite not shooting that much video. But this thing has potential. The only problem (for me) is the lack of stabilization.

That's a promo shot by Sigma, it seems.
I suppose this thing isn't meant for Pentax fans. This thing is about video. That's what you're paying for.
