Pentax K1 + Pentax 15-30mm f/2.8 SuperRes Aperture Series @ 21mm (Includes StdRes Comparison)

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

Pentax K1

In my review of the Pentax K1, this aperture series evaluates the Pentax 15-30mm f/2.8 ED SDM WR from f/2.8 through f/11 on a very demanding target in SuperRes Pixel Shift Mode, including a frame shot with/without pixel shift. Thus it evaluates several behaviors together under real world conditions:

  • Performance of Pentax 15-30mm f/2.8 ED SDM WR across its aperture range on an extremely demanding real-world outdoor subject.
  • Distortion of the Pentax 15-30mm f/2.8 ED SDM WR.
  • Comparison of SuperRes Pixel Shift Mode to StdRes.
  • Whether SuperRes Pixel Shift Mode has benefits at wider apertures.
  • Whether SuperRes Pixel Shift Mode eliminates any aliasing or moiré.
  • Evaluates the Pentax 15-30mm f/2.8 thoroughly.

Pentax 15-30/2.8 Aperture Series @ 21mm, with Pixel Shift: Mosaic (Pentax K1)

Includes ACR processing settings, images up to 28 megapixels, and large crops, all from f/2.8 through f/11.

The entire series is shot in pixel shift mode to critically evaluate both the K1 SuperRes mode as well as the Pentax 15-30mm f/2.8. Also includes an f/11 exposure in StdRes mode for comparison to SuperRes mode—a nice real world look at the advantages of SuperRes mode.


The Pentax K1 in pixel shift mode sets a new quality bar for full frame 35mm images. To my eyes, I doubt that it is possible to better this performance at 21mm with any DSLR or mirrorless camera. And I’d bet it is superior to most medium format cameras (in pixel shift mode).
