Nikon 14-24mm f/2.8G ED

Focus Shift: Nikon 14-24 vs 24-70 on Nikon D800E

This pages offers an study of focus shift with the Nikon AF-S 14-24mm f/2.8G and the Nikon AF-S 24-70mm f/2.8G, two of Nikon’s top-flight zoom lenses.

See also the focus shift study of the Nikon 24mm f/1.4G.

Test scene

The 36-megapixel Nikon D800E was used in DX-crop mode as shown below (~80 cm distance). Focus was on the doll’s eyes, with the ruler as a reference point for observing the amount of focus shift. The doll’s eyes correspond to roughly the “9” mark on the ruler.

Focal length: the tripod was not moved! The 14-24 and 24-70 have very different ideas about what 24mm is! So the two images are not the same size.

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.
