Sigma’s 50-120mm F2.8 is 'an APS-C legend in the making' — and a tempting full-frame alternative

Sigma has announced the 50-120mm F2.8 DC OS Contemporary lens, completing its trio of f/2.8 zoom lenses for APS-C mirrorless cameras. Designed for Sony E, Canon RF, and Fujifilm X mounts, the lens offers an equivalent focal length of 75-180mm. Weighing only 380g and measuring 10cm in length, the lens is positioned as a compact, affordable alternative to bulky full-frame telephoto zooms. Priced at $799, it aims to provide professional-grade performance for portraiture, sports, and event photography without the weight or cost of traditional full-frame gear. While Nikon users currently miss out on this specific model, the lens has already garnered significant praise from the photography community for its portability and optical potential. The product is scheduled for release on October 22, marking a significant expansion for the APS-C ecosystem and challenging the necessity of full-frame systems for many photographers.
