Sigma 45mm f/2.8 DG Contemporary Lens Black for L Mount Summary
The Sigma 45mm f/2.8 DG Contemporary Lens Black for L Mount is a compact full-frame prime and the smallest and lightest optic in Sigma’s Contemporary series. With a focal length that lives between 35mm and 50mm, it offers a natural perspective that works extremely well for street photography, travel, portraits, and everyday shooting.
Despite its modest size, this lens delivers consistent optical performance across the frame. The f/2.8 aperture supports good subject separation from background distractions, while keeping the lens compact and well balanced on smaller L Mount camera bodies. An all-metal construction, aperture ring, and internal focusing system give it a solid, tactile feel without adding unnecessary weight. The black finish provides a discreet alternative to the silver version, working well with modern mirrorless cameras.
As one of Sigma’s DG mirrorless lenses, it is made exclusively for mirrorless systems. It suits photographers and hybrid shooters who want a lightweight prime with great image quality and simple handling, particularly when portability and discretion are important.

Sigma 45mm f/2.8 DG Contemporary Lens Black for L Mount in More Detail
Image quality
The optical design of the Sigma 45mm f/2.8 DG Contemporary provides consistency across the frame while keeping the lens small and lightweight. Sharpness is apparent from the centre to the edges, which is particularly useful for scenes that include both subject detail and background, such as street, landscapes and travel photography. Chromatic aberration is well controlled, and contrast holds up well across a range of lighting conditions.
At wider apertures, the lens produces smooth tonal transitions with gentle background blur. Out-of-focus areas appear clean and unobtrusive, helping subjects stand out with background separation. Stopping down increases clarity while retaining natural rendering, making the lens suitable for both shallow depth-of-field and detailed scenes.
Autofocus performance
Autofocus operates internally, keeping the lens length fixed and helping maintain balance, even on compact camera bodies. Focus is quiet and predictable, which suits for both stills and video recording. The manual focus ring provides a smooth, linear response, allowing for accurate adjustments when working manually or refining focus during filming.
A physical AF/MF switch enables quick changes without going into camera menus. Focus accuracy is consistent across close and distant subjects, supporting a range of spontaneous to deliberate shooting styles.
Video characteristics
For video use, the internal focusing system helps keep camera rigs and gimbals balanced. Focus breathing is kept to a manageable level for everyday filming, and the aperture ring allows exposure adjustments directly from the lens barrel. Its low weight and compact size make it comfortable for handheld shooting or stabilised kits.
Handling and controls
The lens is extremely compact yet includes a metal barrel, rings, and hood, which contribute to reassuring build. The black finish offers a subdued appearance that suits professional environments and everyday use.
The weather-sealed mount provides added confidence when shooting outdoors, and the control layout matches other Sigma Contemporary primes, making it easy to move between lenses without adjusting your handling habits.
