Description — Sigma 24mm f/1.8
The Sigma AF 24mm F1.8 EX DG Macro Lens is a prime wide-angle lens built for full-frame DSLR systems. Its fixed 24mm focal length paired with a f/1.8 maximum aperture makes it a fast option in the wide-angle prime category. The lens is compatible with a broad selection of DSLR mounts — Canon EF, Nikon F, Sony A, Pentax K, and Sigma SA — offering flexibility across different camera ecosystems.
Both autofocus and manual focus are supported, giving photographers the ability to choose their preferred focus method. The 77mm filter thread is a practical fit for photographers who already have filters in that size. At 485g, the lens has a solid build weight.
Note that image stabilization is not included, so steady technique or adequate shutter speed will be needed for sharp handheld shots. This is a DSLR-specific lens designed for photographers seeking a wide, fast prime across multiple camera systems.
