- Does it fit Sony full-frame cameras?
- Yes. It is made for Sony E-mount and covers full-frame sensors. It also works on APS-C E-mount bodies, where it behaves like a roughly 21-36mm lens.
- Can I use filters on it?
- Not standard screw-in filters, because of the bulging front element. You need a rear filter holder or a dedicated large filter system made for this lens.
- Is it good for astrophotography?
- Yes. The constant f/2.8 aperture and strong coma control make it a popular choice for night skies and Milky Way shots.
- How does it compare with the Sony 16-35mm f/2.8 GM?
- The Sigma goes wider to 14mm and is generally regarded as sharper in the corners, but it is heavier and cannot take screw-in filters. The Sony is lighter and more flexible for general use.
- Does it have image stabilization?
- No. It relies on the camera body's stabilization, so pair it with an IBIS-equipped body for handheld low-light work.
- Is autofocus fast enough for video?
- Yes. The stepping motor is quiet and smooth, which suits video, though focus breathing is visible when racking focus.
