- Is f/2.8 worth it over an f/4 zoom?
- Yes if you shoot events, weddings or indoor portraits. The constant f/2.8 gives one stop more light and shallower depth of field than f/4 zooms, which matters in dim venues.
- Does it work on Sony E-mount cameras?
- Yes. The DG DN Art line is made for mirrorless mounts, and this lens comes in Sony E and L-Mount versions. Check the mount before ordering.
- How does it compare with a 24-70mm f/2.8?
- It trades 4mm at the wide end for 35mm more reach. If you shoot people and events more than architecture or tight interiors, the extra reach is the better trade.
- Is the image stabilization useful?
- Yes, especially on bodies without in-body stabilization or for handheld video. It helps at the long end and in low light, but it does not freeze moving subjects.
- What is in the box?
- The lens, front and rear caps, a lens hood and a soft case. A tripod collar is not included.
