About This LensThis Sony E mount prime gives full frame bodies a fixed 24mm wide view. It suits travel, street, interior and landscape work, where wide framing places the subject within its setting. The small size makes it a natural everyday lens. Sony launched it in 2021, and it remains in production. The trade-offs are part of the package. One focal length means you frame by moving rather than zooming. The f/2.8 maximum and the lack of stabilization both limit handheld shooting in dim light, which matters most indoors and at dusk. The sections below cover each point in detail. | |

About the BuildThe lens weighs 5.7 oz (162 g) and measures about 2.68 in (68 mm) across and 1.77 in (45 mm) long. At that weight and size it adds little bulk to a camera bag. The physical score is 86 out of 100. A screw-in filter must match the 49mm thread on the front. | |

About the OpticsThe 24mm focal length frames a wide slice of any scene. It fits whole rooms, narrow streets and layered landscapes that a longer lens would crop away. When a composition feels loose, you step closer to fill the frame. That fixed view encourages a deliberate way of working. The f/2.8 maximum keeps the lens usable indoors and at dusk. You can hold moderate shutter speeds without pushing ISO too far. Photographers who mainly shoot after dark may want a brighter prime, since f/2.8 is the ceiling here. Depth of field stays generous at 24mm, even wide open. Inside a lobby or church, a near doorway and a far wall can both stay sharp. The trade-off is limited background blur, so the lens suits scenes told with context rather than isolated portrait subjects. Close focusing down to 0.8 ft (24 cm) lets you push a near subject large in the frame. A window detail or pavement texture becomes a strong foreground, and the wide view keeps the setting behind it. | |

Features32/100 | |
About the FeaturesThe lens is weather sealed, a construction measure that helps resist dust and moisture at the joints. Sealing lowers the risk of dust and light moisture getting in, though it is not a guarantee against heavy rain. That protection fits its travel and landscape role. There is no image stabilization. In dim interiors, sharp handheld frames need a fast enough shutter speed, a higher ISO or a support. On a tripod the gap disappears. The wide 24mm view forgives small camera movement better than a long lens would. The front glass also lacks a fluorine coating. The features score is 32 out of 100. | |

Construction31/100 | |
About the ConstructionThe design includes aspherical elements, whose special shaping helps correct distortion, where straight edges appear curved. That matters for interiors and architecture, where walls and doorframes should stay straight. Low-dispersion glass helps reduce chromatic aberration, the coloured fringes that can appear along high-contrast edges such as branches against a bright sky. | |
Elements ⓘLens elements refer to individual pieces of glass within the lens. | 8 |
| Groups | 7 |
Aspherical Elements ⓘThe number of aspherical lens elements which can help correct aberrations such as spherical aberration. | 1 |
Bi Aspherical Elements ⓘElements with two non-spherical surfaces | 0 |
Low Dispersion ⓘElements that reduce chromatic aberration | 1 |
Super Low Dispersion ⓘAdvanced elements further reducing chromatic aberration | 0 |
CA Reduction ⓘBuilt-in features to reduce chromatic aberration | 0 |
Internal Focusing ⓘInternal Focusing means that the lens does not change in size during focusing, and the front element does not rotate. | No |
