Sigma Cine Primes range from 14mm to 135mm, all with a common T1.5 maximum aperture (T2.0 for the 14mm and 135mm). With a more than adequate 180 degree focus rotation and a robust mechanical design, the Sigma Cine Primes are an excellent choice for a wide variety of production situations - from small indie projects, up to feature films. Built from scratch, entirely in Sigma's Aizu factory, the Sigma Cine Primes are a tool that cinematographers and ACs are sure to embrace.
