Exceptional Optical Performance
The Rokinon 16mm f/2.0 ED AS UMC CS Lens has been meticulously crafted to meet the demands of today’s high-resolution Pentax APS-C cameras. With its 13-element, 11-group construction, including one Extra-Low Dispersion (ED) and two Aspherical (AS) elements, this lens delivers exceptional image quality with minimal distortion. Every image appears sharp, clear, and full of contrast — whether you’re shooting sprawling cityscapes, dramatic interiors, or the Milky Way under the night sky.
The Ultra Multi-Coating (UMC) reduces ghosting and flare, ensuring maximum light transmission for vivid color reproduction. Even in bright or backlit conditions, you can trust the Rokinon 16mm to maintain clarity and consistent tone across every shot.
Fast f/2.0 Aperture for Low-Light Mastery
One of the standout features of this lens is its wide f/2.0 maximum aperture, which makes it an excellent performer in low-light environments. Whether you’re shooting in dim interiors, capturing nighttime city scenes, or diving into astrophotography, the Rokinon 16mm f/2.0 delivers bright, detailed images without relying heavily on ISO adjustments.
The fast aperture also gives you greater creative control over depth of field. You can easily separate subjects from backgrounds and create stunning bokeh effects — something rare for an ultra-wide lens.
Perfect for Landscapes, Architecture, and Astrophotography
The 16mm focal length (equivalent to 24mm on full-frame) strikes the perfect balance between ultra-wide perspective and minimal distortion. This makes it ideal for capturing landscapes, interiors, and architecture with natural proportion and immersive depth.
Astrophotographers will especially appreciate this lens for its ability to render stars as crisp points of light without coma distortion. Combined with its f/2.0 aperture, it’s a dream for night sky photography — delivering clear, vibrant images even in challenging conditions.
Manual Focus Precision for Total Creative Control
Like many of Rokinon’s professional-grade lenses, the Rokinon 16mm f/2.0 ED AS UMC CS features a manual focus design, allowing for precise control over focus placement. The focus ring is smooth and well-damped, giving photographers the tactile precision needed for fine-tuning focus — especially critical for astrophotography or video work.
This manual operation also ensures quiet, smooth adjustments, making it ideal for videographers who require focus control without the noise of autofocus motors.
Durable and Professional Build Quality
Rokinon has built its reputation on crafting lenses that are both reliable and durable, and this 16mm f/2.0 is no exception. The solid metal housing provides a professional feel while maintaining a balanced weight for handheld or tripod shooting. The 77mm front filter thread also allows easy attachment of ND or polarizing filters — perfect for long exposure landscape photography.
Despite its robust construction, this lens remains lightweight and portable, making it an ideal companion for photographers on the move.
Stunning Color and Contrast
Thanks to Rokinon’s UMC (Ultra Multi-Coating) technology, this lens ensures every frame bursts with natural color and rich contrast. It effectively minimizes reflections and enhances light transmission, allowing you to capture true-to-life tones and textures — from sunlit valleys to dimly lit interiors.
This superior coating makes it particularly useful for high-contrast scenes where other lenses may struggle, ensuring your images remain crisp and visually balanced.
Versatile for Both Photo and Video
The Rokinon 16mm f/2.0 ED AS UMC CS Lens for Pentax K APS-C is not just for still photography — it’s also a fantastic option for filmmakers. Its manual focus control and de-clicked aperture ring (in the Cine version) provide smooth, seamless transitions, making it perfect for video recording. Whether you’re filming wide cinematic shots or immersive travel content, this lens delivers professional-level performance.
