Overview of Sigma 120-300mm

The Sigma 120-300mm f/2.8 DG OS HSM S is an affordable super-tele varifocal lens offering the attraction of a 2.5X focal length range with an f/2.8 aperture.

Build quality, fit and finish

Build quality is an attractive black matte finish similar to an anodized look. The lens appears to contain metal parts and even the lens hood seems to be metal (it feels heavy and is 276g). In pure terms of strictly visual appeal, I rate it as more attractive than the Canon and Nikon super teles. But how its fit and finish hold up over the long term cannot be said here.

The 120-300mm appears to be a very well built-lens in addition to the attractive finish. With apparent use of plenty of metal parts, one might expect long term usage, but of course it is the internal electronic and moving parts that cannot be assessed for durability except by actual long term usage.

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.
