The Xeen 50mm T1.5 is a dedicated cinema lens that delivers a natural field of view for budding filmmakers and cinematographers. Its internal focus design delivers smooth focusing performance and eliminates lens breathing, a characteristic commonly found in standard DSLR photography lenses.
Versatile 50mm Focal Range
The versatile 50mm focal range when mounted to a full-frame camera delivers a natural perspective with excellent colour reproduction and rich detail across the entire frame.
Fast T1.5 Aperture
A bright T1.5 maximum aperture equips you with the versatility of capturing moody low-light scenarios and producing cinematic shallow depth of field effects.
Geared Focus & Aperture Control
The 11 blade iris construction ensures ultra-smooth bokeh results, while its click-less aperture design delivers smooth iris pulls. Geared rings for both focus and aperture control enables you to achieve smooth iris and focus pulls for cinematic style results.
Shared Focus & Iris Ring Positions
Sharing its focus and iris gear ring positions with other Xeen lenses greatly speeds up lens changes in dynamic shooting environments. It enables the Xeen 50mm to be swaped with other Xeen lenses such as Xeen 24mm or Xeen 85mm without having to re-configure the position of your follow focus or iris motors.
Dual Calibrated T-Stop Scales
Calibrated focus and T-Stop scales on both sides of the lens allows you to work freely on the left or right side of the camera. This eliminates the inconvenience of having to flip the lens mount or look at an upside down scale while shooting.
Shared 114mm Front Diameter
Its 114mm front diameter is also common to the Xeen series lenses, allowing you to use the same adapters, anti-reflection donuts or matte box during lens changes.
X-Coated Optics for Improved Contrast
Its outstanding optical performance is designed with the future in mind. Suitable for 4K recording, the 9 element, 6 group construction delivers full-frame coverage and utilises an X-Coating on its optics for excellent contrast and glare protection.
Shared Colour Consistency
Additionally all lenses in the Xeen range are colour matched to a strict factory standard, ensuring minimal colour shift when changing between lenses. This precision improves colour accuracy and efficiency when grading footage shot across multiple Xeen lenses.
Rugged Aluminium Metal Housing
Constructed using a rugged aluminium metal housing, the Samyang Xeen 50mm T1.5 EF Mount Lens is built to satisfy the needs and performance requirements of the most seasoned filmmakers and videographers.
