Why I Consider This Lens
When I looked at the Sigma 18-35mm f/1.8 for Canon, what stood out to me first was the constant f/1.8 aperture.

- Portrait and lifestyle photography
- Indoor and low-light shooting
- Video work where a bright aperture matters
- Travel and general-purpose use
If I use a full-frame Canon body, I would not choose this lens, since it is designed mainly for APS-C cameras.
