Frequently asked questions
What cameras is the 14mm T3.1 Full Frame Ultra Wide Angle Cine DS compatible with?
The 14mm T3.1 Full Frame Ultra Wide Angle Cine DS is a Canon EF, Micro 4/3, Nikon F, Sony E mount lens from Rokinon. Use it on cameras that accept that mount.
Is the 14mm T3.1 Full Frame Ultra Wide Angle Cine DS a full-frame or crop-sensor lens?
This lens covers Full Frame (FX). That is the image circle it is designed to illuminate, so match it to your camera's sensor format.
What is the focal length of the 14mm T3.1 Full Frame Ultra Wide Angle Cine DS?
The 14mm T3.1 Full Frame Ultra Wide Angle Cine DS has a focal length of 14mm.It is a wide angle design.
What is the maximum T-stop of the 14mm T3.1 Full Frame Ultra Wide Angle Cine DS?
The 14mm T3.1 Full Frame Ultra Wide Angle Cine DS has a maximum T-stop of T3.1. T-stop measures actual light transmission, which is the value cine users use for exposure.
Does the 14mm T3.1 Full Frame Ultra Wide Angle Cine DS have autofocus?
The 14mm T3.1 Full Frame Ultra Wide Angle Cine DS is a cine lens designed for manual focus, with geared control for follow focus rather than stills-style autofocus.
What filter size does the 14mm T3.1 Full Frame Ultra Wide Angle Cine DS use?
The 14mm T3.1 Full Frame Ultra Wide Angle Cine DS takes n/a filters. Confirm the thread size if you are using a different mount version of this lens.
What is the minimum focus distance of the 14mm T3.1 Full Frame Ultra Wide Angle Cine DS?
The minimum focusing distance is 11” (0.28m). That is the closest this lens can focus while remaining sharp.
The Rokinon 14mm T3.1 VDSLR ED AS IF UMC II Lens was developed primarily for film and video applications. The cine version of Rokinon's 14mm lens features industry-standard gearing for the focus and aperture ring, and the aperture ring has been de-clicked for smooth iris pulls. The aperture and focus scales have also been relocated to the side of the lens, where it is easier for focus pullers to read them.
This lens is compatible with full-frame sensors and can also be used on APS-C-sized sensors, where the 35mm-equivalent focal length will be 22.4mm. The optical construction incorporates three high refractive index elements, two extra-low dispersion elements, one hybrid aspherical elements, and one aspherical element to reduce chromatic aberration and distortion to produce sharper imagery. Additionally, a UMC coating has been applied to lens elements to minimize lens flare and ghosting for more contrast-rich images.
- Fast T3.1 maximum aperture benefits working in low-light conditions.
- Three high refractive index elements, two extra-low dispersion elements, one hybrid aspherical element, and one aspherical element reduce chromatic aberrations in order to produce greater sharpness and clarity.
- UMC coating improves light transmission and suppresses lens flare and ghosting for more contrast-rich, color-neutral images.
- Geared aperture and focus rings are compatible with standard follow focuses for greater control over adjustment.
- De-clicked aperture ring facilitates smooth, quiet exposure adjustments during recording.
