The Rokinon AF SERIES II 85mm F1.4 for Sony E is the smallest (99.5mm/3.92in length) and lightest (509g/17.95oz weight) among all the large-aperture standard 85mm focal length lenses compatible with the Sony E mount. The AF 85mm F1.4 E II (Large-Aperture Standard) lens delivers a 28.9˚ angle of view for full-frame & 19.1˚ for APS-C, as well as a bright maximum aperture of F1.4, as preferred by full-frame camera users. In particular, optimum resolution is achieved through the optical design of 11 elements in 8 groups (4 HR and 1 ED). Combined with Sony's full-frame image sensor, this lens delivers superior sharpness and contrast in all areas of the image. Fast and Quiet AF Performance Tracking the subject accurately and quickly, the AF also operates quietly and smoothly when shooting video. Rokinon’s Linear STM (Stepping Motor) satisfies both photographers and videographers with quieter and more accurate control of the focusing lens groups. Impressive Background Blur and Bokeh with Bright F1.4 Aperture The AF 85mm F1.4 E II uses a large-diameter aperture to provide smooth background blur. It effectively separates the subject from the background, using a shallow depth of field and adding drama to the scene. The 9 diaphragm blades create smooth and natural bokeh with light splitting. Less Breathing for Shooting Video The AF 85mm F1.4 E II has minimized focus breathing, so there is almost no change in the angle of view when focusing and therefore less screen shake. This is effective when shooting movies with the subject moving forward or backward, or focusing from the front or back. Enhanced Usability with Custom Switch and Focus Hold Button There is a custom switch, which can be set allow adjustment of the aperture by rotating the focus ring. Using the optional Lens Station, you can setup the mode to suit your own preference*. * More functions will be added through firmware updates in the future Customizable Focus-Hold Button Pressing and holding this button will keep the lens locked at the auto-focused distance. The user can also assign to the focus hold button other desired functions through the Custom Key Settings menu of the camera. Short Minimum Focal Distance The minimum focal distance is just 0.85m (2.79ft), so it is versatile and possible to produce a unique perspective close to the subject. This makes it easier to take close-up and dramatic shots of food, portraits and nature. Weather-Sealing Design The usability of the AF 85mm F1.4 E II lens has been developed and enhanced, taking into consideration not only the design but also the user's shooting environment. It has a micro-patterned rubber focus ring, so feels great to operate and weather-sealing also protects the lens from light rain, snow and dust.
