Sigma, as a third-party lens manufacturer, produces a variety of lenses with different specifications and features. The key specifications for a lens typically include:

1. Focal Length Range:

   • In this case, the focal length range is 100-300mm, indicating a telephoto zoom lens capable of capturing subjects at varying distances.

2. Maximum Aperture:

   • The aperture range is f/4.5-6.7. This suggests that the maximum aperture changes as you zoom in, being f/4.5 at 100mm and f/6.7 at 300mm. A variable aperture lens like this means that in low-light conditions, the maximum aperture decreases as you zoom in, potentially affecting the amount of light entering the lens.

3. Lens Mount:

   • Canon EOS Mount 

4. Build and Design:

   • The lens construction, weight, and features like the presence of weather sealing, as well as the quality of the build materials, contribute to the overall usability and durability of the lens.
