The Sigma 135mm T2 Fully Luminous FF High-Speed Prime Lens deserves a place in your professional lens kit. It is built for Sony E-mount mirrorless cameras. With the fully manual operation, the lens gives you control over the final look of the scene. The dedicated focus and iris rings have integrated dampeners to minimize the metallic noise that comes when they hit the endpoint. You can turn the focus ring up to 180° to get long travel distances for the focus points. Refer to the luminous Imperial scale marking to alter the focus parameters when working in low light. The iris ring moves without any clicks to support the video recording. These control rings come with industry-standard 0.8 Mod gear pitches to facilitate the use of follow focus units. With the 9-blade diaphragm, the lens gives pleasant bokeh in your portrait shots. Attach a variety of matte boxes to the 95mm front diameter. This lens works perfectly in harsh weather thanks to its dust- and moisture-resistant design.
