PENTAX K1: Focus Stacking in SuperRes Pixel Shift Mode, 'Pair of Pears'

See my Pentax K1 wish list at B&H Photo.

Pentax K1

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).

Pentax K1: Focus Stacking in SuperRes Mode (Pair of Pears)

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.

Full resolution on the review page be viewed at chrome-like pixel density with outstanding jaw-dropping brilliance on an iMac 5K.
