Pentax K-1

Lenses for Pentax Full Frame

Had the Pentax K1 been a mirrorless camera, it could have had instant compatibility with nearly every brand of lens. As it stands, Pentax K lens selection from Pentax alone is somewhat limited for modern high performance full-frame designs.

Native mount lenses

Existing lenses designed for Pentax APS-C sensor size can of course be used on the Pentax K1, certainly in APS-C crop mode. Some of these even fill the full frame, or nearly so, at least over some portion of the range, so the full frame sensor can be mostly, perhaps even fully utilized (though with likely quality limitations). See my reviews of the Pentax limited lenses as well as my evaluations of the three Zeiss Touit APS-C lenses on full frame Sony, like the Touit 12mm f/2.8 Distagon.

Diglloyd DAP is DSLR-oriented, but also contains workflow and other topics. Much of the focus is on Canon and Nikon but also Pentax and Pentax medium format.

Special emphasis is placed on lens evaluation, focusing on Canon and Nikon and Sigma lenses, but with a few others like Rokinon/Samyang.

  • Make better images by learning how to get the best results right away.
  • Save money by choosing the right lens for your needs the first time, particularly some of the new Sigma Art lenses vs Nikon and Canon.
  • Workflow discusses image organization, raw conversion and post processing. Many examples show processing parameters for direct insight into how the image was converted.
  • Jaw-dropping image quality found nowhere else utilizing Retina-grade images up to full camera resolution, plus large crops [past 2 years or so].
  • Real world examples with insights found nowhere else. Make sharper images just by understanding lens behavior you won’t read about elsewhere.
  • Aperture series from wide open through stopped down, showing the full range of lens performance and bokeh.
  • Optical quality analysis of field curvature, focus shift, sharpness, flare, distortion, and performance in the field.
