For those that remember the Sigma cameras... theres a new one.

Key Features
  • 25.5MP Foveon X3 Quattro APS-H sensor
  • Hybrid (combined phase + contrast detection) autofocus system
  • JPEG, X3F Raw or DNG file output
  • 2.36m dot (1024 x 768 pixel) LCD viewfinder
  • 1.62m dot (900 x 600 pixel ) LCD rear screen
  • Dust and splash-resistant magnesium alloy body
  • In-camera Raw conversion (X3F only)
And the interesting bits...

Full depth SA mount
The obvious appeal of using an existing mount is that the lenses already exist for it. Sigma produces SA mount versions of 39 of its lenses, which plausibly means the Quattro H has more native lenses available than any other mirrorless camera.

DNG capability

Shame it's the Quattro sensor rather than the Merrill.

Comments elsewhere suggest anything less than an ART lens will not work the sensor to its capabilities, which somewhat reduce the quantity of native lens support but in no way lessens the quality of native lens support. The SA mount makes it less flexible than most other mirrorless systems

It seems an age since this was announced.
 
They certainly take the prize for the ugliest camera! I understand why they've included the adaptor built in to the body to use existing lenses and it's the output that matters but they could have tried a bit harder on the overall design.

Have to agree, Sigma make lovely designed lenses then they come out with this monster! :D lol

Agreed functional may (just) cover it ;) - given how well their latest lenses look it seems a shame.
 
This looks a real Marmite camera but you gotta love it :D or at least admire it and Sigma for doing what no one else seems interested in.

Just on the price, I can't see the problem as it's a quality niche camera for the price of an arguably rather ordinary by comparison mid range CSC.
 
Incorporating a lens spacer adaptor into the body design to save them designing new lenses is sensible from their costs point of view but surely you could do the same with a Canon M5>EOS adaptor or Sony A6K>LE-A4 and have the same range of available lenses whilst accepting the ugliness/increased body size? I'm also struggling to see how $1200 is a good price? I understand that the Foveon sensor offers something different from other sensors but it still has poor high-ISO and dynamic range which are two things that everyone seems to berate other manufacturers for if they can't shoot a black cat in the pitch black.

The alternative CSC at that price is an A6500 or XT2 and I know I'd rather choose one of those.

They are very different tools.

My basic kit is an X-E2 and all three Merrills. Anything that's a moving subject and requires AF or needs an ISO above 200 and the X-E2 is what I reach for. But if the situation is within the sweet spot of the Merrills then they're my first choice. I also disagree with comments about their dynamic range. If you're shooting with Foveon and ETTR based on the blinkies you'll lose out on dynamic range, there's at least two stops of image data hidden in the blinkies. The highlight recovery of a Foveon sensor approaches the shadow recovery of the latest Nikon/Sony sensors.

The trick I think Sigma have missed is in not going straight for full-frame rather than APS-H - and in going for the Quattro rather than Merrill sensor layout. The Merrills seem to have a bigger loyalty base than the Quattros, and the term "full-frame" has an aura around it that translates into desire/demand.

Of course the ultimate would be a 645 Merrill sensor, stick a fixed lens 60mm on the front and you've a digital GA645. Or make an ILC from it with three native lenses (30/60/120). It'd be a slow, methodical camera - but there's a niche for that.
