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
What camera mount does this Rokinon cine lens use?
This lens is designed for Micro Four Thirds (MFT) mount cameras, such as those from Panasonic and Blackmagic Design.
What is the difference between T-stop and F-stop on this lens?
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.
Does this lens have geared focus and aperture rings for use with follow focus systems?
Yes, as a dedicated cine lens, it features geared rings designed for smooth, precise control with standard follow focus rigs.
What filter size does this lens accept?
It accepts standard 77mm threaded filters, which is a common size shared across many professional lenses.
How many aperture blades does this lens have and how does that affect the image?
It has 9 aperture blades, which produce smooth, rounded bokeh highlights when shooting at wider apertures — a desirable quality for cinematic footage.
