Samyang AF 85mm f/1.4 FE (Sony Full-Frame E-Mount) Lens
- Full-frame 35mm
- 85mm focal length
- f/1.4 aperture
- 11 elements in 8 groups
- 9 diaphragm blades
The AF 85mm f/1.4 FE cherishes Samyang's world class optical technology while envisioning a new leap forward, with its quick and accurate autofocus performance and excellent resolution. Its complex optical construction is comprised of 11 glass elements, among which are special High Refractive (HR) glass, which successfully allows both a compact size and high image resolution. The achromatic design, incorporating Extra Low Dispersion (ED) glass, effectively correct chromatic aberrations and minimise peripheral softness, creating lively images in vivid colour.
The AF 85mm f/1.4 FE's optical design minimises optical aberrations, whilst maximising the image quality from corner to corner. The detailed rendering results in exceptional image quality, even on the latest high-resolution full-frame cameras and its bright maximum aperture means you can enjoy this excellent performance even when shooting indoors or in darker conditions.
The lenses attractive bokeh is created through precise lens polishing and adds a great feeling of depth and space in your photographs. Also, the aperture mechanism comprises 9 precisely-controlled iris blades, providing natural, circular, out-of-focus highlights at all apertures. With this smooth bokeh, achieved through various optical technologies, you can create images full of character in your portrait or subject photography.
A Feeling of Depth
The short telephoto length, combined with the wide maximum aperture of f/1.4, enables photographers to achieve a dramatically shallow depth-of-field, setting your pictures apart from those taken with other lenses. This optic offers great creative freedom: it yields images with depth, whilst maintaining an appropriate distance from the subject; it separates the subject and background naturally, providing an impressive visual feeling of depth.
Control Chromatic Aberration
The AF 85mm f/1.4 Fe features a total of 11 glass elements. The Ed (Extra Low Dispersion) elements have been incorporated into its precise achromatic design. This design corrects chromatic aberrations and creates quality results, with peripheral softness also being well-controlled.
Complex Optical System
Four HR (High Refractive) elements, made of special materials with an outstanding refractive index, improve optical performance and enables a compact optical design. The AF 85mm f/1.4 Fe was design from the ground-up with this technology, to lessen its users' burden with a shorter length and smaller size.
Fast and Efficient Autofocus
The DLSM (Dual Linear Sonic Motor) works with ultrasonic vibrations, which cannot be heard by human ears, to successfully give a silent autofocus performance. The accurate high frequency signals, controlled with Samyang's own protocols, precisely operate the DLSM. Specialists in optics, mechanical engineering and electronics have researched cooperatively to give these powerful results for a short telephoto lens. The introduction of DLSM technology to an 85mm lens means that you can comfortably and silently capture the subjects you want, with quick efficiency.
Weather Sealed Design
The aluminium body has been designed with precision by mechanical engineering specialist and only has three spaces in its basic design. Weather sealing covers even these small spaces to effectively protect the lens from dust and rain. This protective deigns enables users to capture the moment outdoors in any environment, providing the dependability you need to keep shooting,
Samyang's Ultra Multi-Coating (UMC) technology is applied through a thorough cleaning process, followed by Ion-Beam Sputtering (IBS), which controls the spread of reflections while still enabling a high transmittance of light. This UMC technology reduces unwanted reflections and provides crystal clear image quality, minimising flare and ghosting effects in high contrast environments, such as backlit pictures and nightscapes.
