See my Pentax K1 wish list at B&H Photo.
The Pentax K1 SuperRes pixel shift mode (“SuperRes” mode) merges 4 exposures into one raw file, in effect providing a full RGB sampling at each photosite, vs red or green or blue (only) in StdRes / conventional mode.
Because SuperRes mode has a true RGB sample at each pixel, it avoids troublesome color moiré effects as compared to conventional Bayer matrix sampling (StdRes mode).
Just how effective is the Pentax K1 SuperRes pixel shift mode with moiré?
Product and studio photographers needing moiré control will find this a jaw-dropping comparison. Please be seated before viewing. Or anyone photographing subjects that must avoid moiré (think things as simple as window blinds or window screens, or mosquito netting on tents).
The about $1796 Pentax K1 is a must-see for certain types of photography. It has no peer in the DSLR or mirrorless world in terms of addressing moiré. Now why don’t Sony or Nikon or Canon offer this feature? Gah!
Alternatives are out there, like the about $45,000 Hasselblad H5D-200c Multi-Shot Medium Format DSLR (that’s the cost of 25 Pentax K1 DSLR bodies). The battle for depth of field with medium format is no picnic. Pros should be taking a hard look at the K1.
Shown below is a crop in StdRes mode (no pixel shift).
