Cinematography Popular among cinematographers too, because the lens provides a wide cinematic feel, minimized breathing, no edge distortion while panning, and the overall weight and internal focus design makes it an ideal choice for gimbal work. Advanced Optics The new Tokina atx-i 17-35mm f/4.0 FF incorporates a complex optical design, with 13 elements in 12 groups. The proprietary optical design uses 3 aspherical lens elements to achieve superior contrast, sharpness, and correct for spherical aberrations. Additionally, Tokina uses two super-low dispersion glass elements to control chromatic aberrations. The lens provides super-low distortion and low light fall-off for straight lines and minimal exposure vignetting. Perfect for architectural, landscape, astrophotographers, and cinematographers
