Compact 56mm Prime for Sony E APS-C

The Sigma 56mm f/1.4 Contemporary DC DN is a lightweight mid-telephoto prime built for Sony E-mount cameras with APS-C sensors. Its bright f/1.4 maximum aperture gathers ample light for indoor and evening shooting while producing shallow depth of field. The stepping motor drives fast, quiet autofocus suitable for both stills and video work.

Suited to portrait and low-light shooters

Photographers who want a small, fast telephoto for subject isolation will appreciate the compact dimensions and smooth focus transitions. Videographers benefit from near-silent AF operation during recording. Buyers needing zoom flexibility or full-frame image-circle coverage should look at other lens types.

55mm filter thread and 28.5° angle of view

The lens accepts 55mm screw-in filters for polarisers or ND control. Its 28.5-degree diagonal angle of view on APS-C delivers a natural portrait perspective. An SLD glass element helps suppress axial chromatic aberration across the aperture range.

Questions about this item

How do I mount this 56mm f/1.4 lens on my Sony E-mount body, and what step do people often miss?

Align the white mounting index on the lens barrel with the matching dot on the camera, then twist clockwise until it clicks; the step many miss is leaving the rear cap on or forgetting to remove the front cap before shooting.

What maintenance will this 55 mm filter-thread lens need over time?

Clean the front and rear glass with a blower and microfibre cloth when dust appears, check the 55 mm filter thread for grit before attaching filters, and exercise the focus ring periodically if the lens sits unused for months.

What limit appears first during extended video recording with the stepping-motor AF?

The 28.5° angle of view on APS-C sensors means any sensor-heating time limit imposed by the camera body will be reached before the lens itself shows thermal or focus-drift issues.
