Bringing advanced focus control to the masses, the TTArtisan Tilt 50mm f/1.4 Lens is an otherwise conventional, normal length prime lens for full-frame Sony E-mount cameras. It gives you the power to control the angle of the focus plane up to 8° and can be rotated up to 90° to apply the effect in any direction. It boasts a bright f/1.4 maximum aperture, which allows it to perform in challenging lighting conditions as well as providing depth of field for isolating subject matter more efficiently. Made entirely of metal, it features a classic manual design with a knurled focus ring that provides smooth, continuous focusing motion, as well as being compatible with a number of focus follow rigs, ideal for the video-centric creator. An optical design of seven elements in six groups includes two high refractive index elements, intended to improve chromatic and geometric aberrations. A perspective control lens providing up to 8° of tilt angle, giving you the freedom to adjust the plane of focus to match your subject, and to create a wide range of unique visual effects. Video-specific optimization: The focus ring and aperture ring have been designed to fit the majority of focus following rigs, standard practice in most cine lenses. Featuring a 50mm focal length, this lens can be used as a standard optic when the tilt mechanism is not necessary. Bright f/1.4 maximum aperture, creating a narrow depth of field ideal for subject and background separation in portraits when not using the tilt mechanism. A 7-element, 6-group optical design includes high refractive index glass elements to combat geometric distortion and spherical aberrations for improved sharpness and accurate rendering. The 12-bladed diaphragm contributes to a pleasing bokeh quality.
