Lens OverviewRokinon 45mm T1.9 FE

The Rokinon Cine AF 45mm T1.9 is a prime lens built for the Sony E mount, designed with cinema and video production in mind. Covering a full-frame image circle, it sits in the standard focal length range — making it a versatile choice for a wide variety of shooting scenarios. The T1.9 maximum aperture allows for strong light-gathering capability and the potential for shallow depth of field in cinematic work.

One of the more practical aspects of this lens is its support for both autofocus and manual focus operation, giving shooters the flexibility to switch between run-and-gun AF-driven capture and precise manual pulling for narrative or controlled productions. At 280g, it is a lightweight option for a full-frame cine lens, which matters considerably when mounting on gimbals, drones, or other motion rigs where balance and payload are key concerns. The 67mm filter thread accommodates common filter sizes used in video production.

With no image stabilization on board, shooters will need to rely on in-body stabilization or external rigging for smooth handheld footage. Overall, this lens targets Sony E-mount cinema and video users who want a compact, fast, autofocus-capable prime in the standard focal length range.

Key FeaturesRokinon 45mm T1.9 FE

DescriptionRokinon 45mm T1.9 FE

The Rokinon Cine AF 45mm T1.9 is a prime lens in the standard focal length range, built specifically for the cinema and video camera system category. It covers a full-frame image circle and is designed exclusively for the Sony E mount. The T1.9 maximum aperture delivers solid light transmission performance, useful in lower-light shooting environments and for achieving subject separation.

Shooters benefit from both autofocus and manual focus capabilities, giving them flexibility whether working on fast-paced run-and-gun productions or more controlled narrative shoots. At 280g, the lens is notably lightweight for a full-frame cine prime, making it well-suited for gimbal systems and aerial platforms where every gram counts. A 67mm filter thread provides compatibility with widely available filter accessories.

It is worth noting that no image stabilization is included, so stabilization must come from the camera body or an external rig. For Sony E-mount videographers and cinematographers seeking a compact, fast, autofocus-capable standard prime, this lens covers the core bases efficiently.

ProsRokinon 45mm T1.9 FE

  • Fast T1.9 maximum aperture supports strong light-gathering performance for cinematic shooting
  • Full-frame coverage on Sony E-mount cameras means no crop concerns with compatible bodies
  • Dual focus support — both autofocus and manual focus — offers flexibility across production styles

ConsRokinon 45mm T1.9 FE

  • No image stabilization (listed as 'None'), so smooth handheld shooting depends on external solutions or in-body IS
  • Single-mount option — only available in Sony E mount, limiting compatibility with other camera systems
  • Fixed 45mm focal length with no zoom capability may require lens swaps in dynamic shooting environments
