Questions our customers asked
Will the Sigma 28-70mm F2.8 DG DN work on my Sony camera?
Yes. This is a full-frame (DG) lens for Sony E-mount, so it covers full-frame Sony bodies (like the A7 series) and also mounts and works fine on Sony APS-C E-mount bodies (like the A6000 series), where the range behaves like roughly 42-105mm equivalent.
What's in the box with this lens?
The lens, the lens hood (LH706-01), a front cap (LCF-67mm III) and a rear cap (LCR II).
Does the F2.8 aperture stay constant across the whole zoom range?
Yes, F2.8 is a constant maximum aperture from 28mm through to 70mm, so exposure and depth of field don't shift as you zoom, and low-light and background-blur performance stay consistent throughout the range.
A constant F2.8 standard zoom, small and light enough to carry every day.
