Features 1、Near Zero Breathing: This lens controls the breathing effect when focusing and stabilizes the image even when the vignetting occurs when refocusing. 2、T2.0 Aperture: It offers a maximum T2.0 and minimum T16 constant aperture, and the amount of light intake always remains constant. The 12 aperture blades create soft bokeh and natural focus transitions for bright vivid images in low light situations. 3、Uniform Color Balance: The whole series of lenses have a uniform color balance. After changing lenses or switching between different materials it still has a uniform color to reduce post processing. 4、270 Degrees Focus Stroke: Stepless focus gear design for ultra long 270 degrees focus stroke. It can be adapted to a variety of focus followers, to ensure accurate focus during the shooting process. Focus movement is more delicate, in line with the requirements of professionals on focusing performance. 5、Convenient Operation: This lens has a uniform gear position and front lens aperture, so there is no need to adjust the position and other accessories after changing the lens. 6、Applicable Modes: For FX3 A7S A7S2 A7S3 A7M2 A7M3 A7M4A1 A7 A9 A9II A7R A7R2 A7R3 A7R4A7RIV A7C A6400 ZVE 10 for SONY E mount camera.
