Questions about this item

What type of camera body is required for the SIGMA 45mm f/2.8 DG Contemporary lens to function?

It requires a Sony E-mount camera body and is designed for full-frame sensors, though it also operates on APS-C E-mount bodies.

How does the lens perform when paired with an older Sony E-mount camera?

The lens mounts natively on any Sony E-mount body; electronic aperture control and EXIF data transfer work as they do on newer models.

How can I verify the 7-blade diaphragm is producing the intended rounded bokeh?

Shoot wide open at f/2.8 against point light sources; the out-of-focus highlights should appear circular rather than polygonal.
