This Sigma Kit of Five T1.5 FF High-Speed Prime Lenses assembles focal lengths in a hard-shell case. Use this wide range of primes to capture high-resolution, 8K-suitable images with your EF-mounted full frame camera. The cine-oriented style of these primes feature clickless apertures, geared focus and iris rings, and dual focus scales marked in feet. Standardized color reproduction, common 95mm front diameters, and similar physical attributes across the line of lenses enable smooth switching between focal lengths.
