Lens Overview — Rokinon 14mm T3.1 DSX

The Rokinon 14mm T3.1 DSX Cine Lens is a manual-focus, ultra wide-angle prime designed for full-frame coverage, available across a broad range of mounts including Canon EF, Nikon F, Sony E, Micro Four Thirds, Canon RF, and L-Mount. With a maximum aperture of T3.1, this lens is built around cine-standard T-stop calibration, making it a practical choice for videographers and focus pullers who need consistent, repeatable exposure values across a matched set of glass. The 14mm focal length puts this firmly in ultra wide-angle territory, making it well suited for expansive environmental shots, architectural work, and cinematic wide establishing frames.

As a prime lens, it delivers a fixed perspective with no zoom mechanism to complicate the optical path. Focus is entirely manual, which aligns with professional cine workflows where a dedicated focus puller handles critical focus during a take. The lens covers a full-frame image circle, meaning it can be used without vignetting concerns on full-frame camera bodies, while also being compatible with smaller sensor formats through the Micro Four Thirds mount option.

Weighing in at 650.2g, it offers a substantial but manageable build for handheld or rigged camera operation. No image stabilization is present, which is typical for dedicated cine primes where stabilization is generally handled at the rig or camera body level.

Description — Rokinon 14mm T3.1 DSX

The Rokinon 14mm T3.1 DSX Cine Lens is a manual-focus ultra wide-angle prime built for full-frame coverage and available in six mounts: Canon EF, Nikon F, Sony E, Micro Four Thirds, Canon RF, and L-Mount. The T3.1 maximum aperture is expressed in cine-standard T-stops, providing consistent and exposure-matched performance across a lens set — a key requirement in professional video production. At a fixed 14mm focal length, this prime delivers a committed ultra wide-angle view ideal for cinematic establishing shots, interior spaces, and expansive landscapes.

Weighing 650.2g, the lens is substantial enough to feel well-built on a professional rig without being unwieldy. Focus is fully manual, making it a natural fit for cine workflows where a focus puller operates the lens independently. There is no image stabilization, so stabilization needs to be managed at the camera body or rig level.

The full-frame image circle means no cropping concerns on full-frame bodies, while the Micro Four Thirds and other mount options extend usability to smaller sensor cameras.
