The Sigma 135mm T2 Cine E Mount is a lens designed specifically for cinematography and features industry-standard 0.8M gears, a focus scale marked in feet in luminous easy-to-read paint, and a 180° barrel rotation. This cine prime has no plastic parts it sports an all-metal body with sealed rings and mount, making it splash and dust-proof. The optical performance has the resolving power for high resolution shooting up to 8K. The coatings on Sigma's cine line are the same as on their Art series lenses, simplifying color correction when using Sigma lenses from other lines in the same project. The Sigma 135mm T2 Cine is ideal for E mount full frame and crop frame ultra-high resolution sensor cameras for projects that demand the highest performance.
