The Sigma 14-24mm f/2.8 and the Sony 12-24mm are both full frame ultra wide zooms for E-mount cameras. The Sigma keeps a bright f/2.8 aperture, which suits night skies and low light, while the Sony reaches a wider 12mm. Sony has offered 12-24mm lenses with different maximum apertures, so confirm which one you are looking at and check exact specs on each maker’s page.
What Each Lens Is For
Ultra wide zooms are used for landscapes, architecture, interiors, real estate and astrophotography. They exaggerate perspective, stretch objects near the edges and fit a lot into the frame.
Key Differences to Weigh
- Wide end: 12mm shows noticeably more of the scene than 14mm. That helps in tight interiors and dramatic foreground compositions.
- Aperture: The Sigma holds f/2.8 across its range. Sony’s 12-24mm lenses come in different aperture classes, so check which one you mean. A brighter lens makes night sky shots easier at lower ISO.
- Size and weight: Faster designs usually grow larger. Compare the dimensions and weights on both makers’ pages.
- Filters: Bulbous front elements limit ordinary screw-on filters. Check each lens for filter options, rear slots or holder systems.
- Autofocus and features: Compare focus motors, customizable buttons and how well each works with your camera’s autofocus modes.
- Distortion and corners: Ultra wides depend on software corrections for some distortion. Look at sample images from independent sources.
| Factor | Sigma 14-24mm f/2.8 | Sony 12-24mm |
|---|---|---|
| Wide end | 14mm | 12mm |
| Aperture | f/2.8 constant | Depends on the version |
| Best for | Night skies, low light | Tight spaces, widest views |
How to Decide
- Decide how often you shoot at night or in dim places. If it is frequent, favor a bright aperture.
- Think about where you shoot. Small rooms and cramped locations benefit from 12mm.
- Check how you plan to use filters, especially for long exposure landscapes.
- Compare weight if you hike with the lens.
- Confirm the exact Sony model, its aperture and its mount before comparing.
Extra Tip
Compare sample images from independent photographers taken in conditions similar to yours, and look at the corners and edges as well as the center, since that is where ultra wide designs differ most.
FAQ
Is two millimeters of extra width a big deal?
At this end of the range, yes. A change from 14mm to 12mm gives a visibly wider view, especially in indoor shots and close foreground subjects.
Can these lenses work on APS-C bodies?
Yes, an E-mount full frame lens fits APS-C E-mount cameras, but the view is narrower because of the crop.
The Short Version
Choose the Sigma 14-24mm f/2.8 for night work and low light, and choose the Sony 12-24mm when the extra width matters most. Verify the model and details on each maker’s page. We have not used these lenses ourselves.
