Sigma I Series. The Sigma 45mm f/2.8 DG C belong’s to Sigma’s 1 Series group of lenses, which is a collection that prioritizes compactness without sacrificing performance. These lenses offer all-metal construction with precision-cut aluminum, an elegant finish, and pleasingly tactile knurled focus and aperture rings.

Stepping Motor. Equipped with a stepping AF motor, this lens has admirable autofocus speeds for videography. This is complemented by a manual aperture ring and an AF/MF toggle with a raised arc shape for fast switching. Please note that the aperture ring is not de-clickable and has 1/3-stop clicks.

Practical Portrait Prime. This lens is the ideal “walking around” lens, with a portrait-length view that’s just slightly wide to better capture the subject’s environment. This, plus its f/2.8 maximum aperture, makes this a flexible and practical lens for everyday subjects and street photography.

Try it with These L-Mount Cameras. The portable nature of this lens makes it a great option for shooters on the go and pairs well with slightly more compact cameras like the Panasonic Lumix S9, the Sigma BF, and the Sigma fp L. However, it’ll work with any L-mount system.
