The Samyang 85mm F1.4 Renewal UMC II for Nikon Full Frame, De-Clicked & Weather Sealed Lens offers an improved design with better balance and improved grip to its predecessor. A 9-bladed aperture produces smooth pleasing bokeh with a circular nature when shooting wide-open. Stopped down the lens is both sharp and high resolving with clear 18 point stars or sunburst from in-scene light sources.
A user de-clickable aperture allows you to set in-between f-stop values and allows for smooth exposure changes during video recording.
The Samyang 14mm F2.8 Renewal UMC II is a well-corrected lens which produces great out of focus rendition thanks to its 9-bladed aperture. It uses one Hybrid Aspherical Lens to minimize spherical and distortion aberration for the sharpest possible image quality.
A 9-bladed aperture helps to produce pleasing bokeh (out of focus areas) with a circular nature. When shooting stopped down to a small aperture this lens will create a clear 18 rays star or sunburst effect around bright in-the-scene-light sources.
By a simple twist of the aperture ring, it's possible to change how the aperture behaves. The de-clicked (free) setting allows for fine adjustments while recording, without 'clicking' or exposure steps between different f-stops. Using the click setting the lens behaves more like a traditional still photography lens with distinct exposure steps, clicks and tactile feedback.
The renewed and updated design features a balanced approach which has produced a consistent and streamlined lens with or without the lens hood mounted. A new micropatterned focus ring offers improved grip and a depth-of-field scale make it easy to calculate which part of the scene will be in focus at a given aperture.
Protective design features enable users to capture moments outdoors in any environment, providing the dependability you need to keep shooting.
