See my Pentax K1 wish list at B&H Photo.
The Pentax K1 in SuperRes mode is an ideal camera for focus stacking in the studio still-life photography, since Motion Correction with ACR is not an issue for still-life subjects, and all color moiré issues are avoided, and a brilliance and detail can be had that is not seen with any other DSLR (as of May 2016).
This example still-life explores a simple focus stack using six exposures shot in APS-C crop mode using the K1 SuperRes pixel shift mode. APS-C crop was used for depth of field reasons and because getting closer with the Sigma 35/1.4 DG HSM Art would have meant blocking the wonderful natural lighting (a 50mm or 100mm would have been agreeable, but were not available).
Shot in SuperRes mode for all frames. Presented in both color and B&W at full camera resolution from APS-C crop mode. A frame at f/9 without focus stacking is included for comparison, also in color and B&W—thus this is a 4-way look at the results.
Zerene Stacker was used for focus stacking (DMAP). Impressively fast and straightforward, this was the first time I had ever used it and yet I had the stack done in under 5 minutes, a testament to simple but thoughtful design.
