Overview

The Rokinon 35mm T1.5 Cine DSX is a purpose-built cinema lens designed for Micro Four Thirds mount cameras. Its optical formula — 12 elements arranged in 10 groups with ultra multi-coating — delivers sharp, high-contrast images with well-controlled chromatic aberration and minimal flare. The fast T1.5 aperture opens up low-light shooting possibilities and produces beautifully shallow depth of field, while the 9-blade aperture diaphragm ensures that out-of-focus highlights render as smooth, rounded circles rather than harsh polygonal shapes.

As a dedicated cine lens, the DSX35-MFT is built around the needs of filmmakers rather than photographers. The focus and aperture rings are geared for compatibility with industry-standard follow focus systems, and the T-stop aperture marking ensures accurate, repeatable exposure settings when matching across multiple lenses in a kit. The 77mm front filter thread accommodates matte boxes and threaded ND or polarizing filters. With a 63.1-degree angle of view on full frame (43.9 degrees on APS-C, and narrower still on MFT due to the 2x crop factor), this lens delivers a moderate telephoto perspective on Micro Four Thirds bodies — well suited for interviews, narrative close-ups, and detailed compositional work where subtle compression and subject isolation are desired.

Pros & Cons

👍 Pros

  • T1.5 maximum aperture allows shooting in low light and produces shallow depth of field for cinematic separation.
  • 12 elements in 10 groups with ultra multi-coating delivers sharp images with controlled flare and ghosting.
  • 9 aperture blades create smooth, pleasing bokeh in out-of-focus areas.
  • 77mm filter thread is a common professional size, making it easy to share filters across a lens kit.
  • Dedicated cine housing with geared rings integrates cleanly with follow focus and lens control systems.

👎 Cons

  • Fully manual lens with no autofocus or electronic aperture control, requiring skilled manual operation.
  • On MFT sensor cameras, the 35mm focal length produces a 70mm equivalent field of view, which is tighter than a traditional 35mm wide-angle perspective.
  • The lens is heavier and larger than comparable photography-only 35mm lenses due to its cine-style housing.
  • No image stabilization, so handheld shooting at longer effective focal lengths requires a gimbal or steady technique.

Frequently Asked Questions

This lens is designed for Micro Four Thirds (MFT) mount cameras, such as those from Panasonic and Blackmagic Design.
The T1.5 rating is a T-stop, which measures actual light transmission through the lens rather than the theoretical maximum aperture (F-stop). This makes exposure matching between different cine lenses more accurate and consistent.
Yes, as a dedicated cine lens, it features geared rings designed for smooth, precise control with standard follow focus rigs.
It accepts standard 77mm threaded filters, which is a common size shared across many professional lenses.
It has 9 aperture blades, which produce smooth, rounded bokeh highlights when shooting at wider apertures — a desirable quality for cinematic footage.
