Crops at 24mm — Left Edge

All the lenses require f/5.6 to “clean up”, and all the lenses show lateral chromatic aberration to varying degrees.
Other comments:
- The 14-24 is good from wide open, improving incrementally until f/8, but doesn't quite match the 16-35 or 17-35 in micro contrast in the f/5.6 - f/8 range.
- The 16-35 remains low in micro contrast from f/4 - f/5.6, it requires f/8 to “pop”. At f/8, the 16-35 is excellent, the best of the bunch, with excellent micro contrast.
- At f/4, the 17-35 delivers the best result. It peaks nicely at f/5.6, a result consistent with my years of past experience. But at f/8 the 16-35 comes on strong.
- The 24-70 never “cleans up”, retaining a slightly soft look at all apertures.
- The 24/2 is very low contrast and smeared until f/5.6, where it suddently “pops”, improving further to its peak at f/8.
- All the lenses show loss of contrast at f/11, though the 16-35 seems to hold up slightly better.

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.
