Canon 24mm f/1.4L II

In-depth comparison to EF 16-35/2.8L II

On this page are compared the 24/1.4L II and the 16-35/2.8L II. These are two radically different lenses, designed for different purposes, yet there is no doubt keen interest at 24mm as to which lens can deliver the best results. The two lenses are very similar in size and weight, and so for that “price”, we can hope that the 24/1.4L II will deliver superior results if we are to carry it in our bag.

Architectural shooters will be concerned with distortion, a good reminder that sharpness is not the only requirement. See the Distortion page.

The test subject is planar (flat). Obviously, a lens with field curvature is going to find off-center detail a challenge, and both of these lenses have field curvature. Stopping down mitigates the problem for both lenses; the naive user will conclude simply that the lens is soft off-center (or soft in the center depending on focus). Most real 3D subjects are more forgiving, but see Varying Sharpness. Landscape shooters should exercise care with subjects involving distant horizons; these will be blurred off-center unless the lens is stopped down to f/8 - f/11 (observed in quite a few field shots).

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.
