Crops at 28mm — Right Edge
Right edge
All of the lenses need f/8 here.
- At f/2.8, the 17-35 and 28-70 and 28/2 are all badly smeared. The 24-70 is quite goood, but with some smearing at upper right.
- At f/4, the 16-35 takes the lead, with only some slight softness at upper andn overall low contrast. The 17-35 still look terrible. The 24-70 is looking very nice but still with some softness at upper right. The 28-70 has improved greatly from f/2.8, but is still soft. The 28/2 remains smeared.
- At f/5.6, the 16-35 and 24-70 are looking great with the 28-70 very close. The 17-35 is still smeared and the 28/2 is starting to look reasonable.
- At f/8, peak performance is reached for all lenses. The 16-35 looks excellent, the 17-35 remains soft, the 24-70 and 28-70 look excellent, the 28/2 is very close.
- At f/11, there is nothing to be gained, though the 17-35 might be beneffiting slightly.

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.
