[Brightcolours]

What I think:

 

• Very refreshing styling, reminiscent of english or danish cottage industry audio
  
• Moronic tha they went the Pentax K01 way. Mirrorless without the mirrorless advantage (built in mirrorbox without a mirror). They could have easily gone for a short flange distance and used an adapter to mount the SLR lenses, and still give the option to allow mounting of shorter flange distance (and for instance make it possible to use the Sigma 30mm DN). So now you have a mirrorless camera,, and the smallest normal you can use is the big and heavy 35mm f.4 Art (for the H version, at least the other version has that one small prime (30mm f1..4 DC).
  
• No AA-filter. Not a fan of the false detail/fake sharpness look at all.
  
• I do not get the Quattro idea totally? They still work in layers, so you still have that massive light loss resulting in truly low DR and very noisy results ate moderate ISO settings, still the same colour issues, yet without capturing all colours at all pixels. 
  
• At least they used the blue channel for the actual detail, meaning that they found an effective way of minimising diffraction softening effects with smaller apertures (kinda.. Only in parts where there is a blue component in the light).
  
• Same thing as with other Sigmas: limited RAW converter choice.
  

So that sums it up really. Nice and quirky for good light low ISO shooting, disliking the AA-lessness of it and not getting the silly choice of DSLR lenses only.
