Supreme compactness & performance
Despite the small form factor of the 45mm F2.8 DG DN | C, there is no sacrifice to performance, capturing the finest details on high-resolution full-frame cameras.
This highly versatile 45mm lens delivers smooth bokeh effects wide open, with incredibly sharp rendering when stopped down, while a controlled spherical aberration ensures a soft blur gradient from the front to rear of the subject.
Stylish, robust construction
Luxuriously crafted of all-metal components to guarantee durability and style, each I series lens is the true embodiment of functional beauty, with a tactile, ergonomic feel that also makes it a pleasure to use.
Dust and splash resistant mount
Rubber sealing at the lens mount helps to keep dust and other foreign bodies from entering the lens or the camera's sensor chamber.
High-precision, rugged brass bayonet mount
The brass mount combines high precision with rugged construction. Its treated surfaces and enhanced strength contribute to the exceptional durability of the lens.

For Sony & L-Mount shooters
SIGMA's DG DN lenses are made exclusively for mirrorless cameras, including Sony E-mount and L-Mount (SIGMA, Panasonic, Leica) systems. These full-frame lenses are designed to take advantage of the benefits offered by mirrorless camera bodies, including more compact dimensions, in-camera corrections, and improved autofocus technology.
The one-and-only I series
SIGMA I series lenses are premium, compact prime lenses that are both strikingly beautiful and optically impressive. With full-frame coverage, all-metal construction, exceptional autofocus performance, and gorgeous (yet functional) touches like a knurled manual aperture ring and a magnetic lens cap, I series lenses are designed to enhance both the artistic potential and the tangible experience of mirrorless photography.
Make sure you get your 4-Year Warranty
All SIGMA lenses come with a 4-Year Warranty in the US, but only if you buy from SIGMA America directly or a SIGMA Authorized Dealer. Gray market importers undercut legitimate retailers, deceive well-intentioned customers, and sell products that are ultimately not eligible for warranty service. Make sure you are buying from a trusted source so your lens is covered!
