Rokinon 50mm T1.5 Cine DSX Overview

From Manufacturer

Update your cinema lens set with this 50mm T1.5 DSX High-Speed Cine Lens from Rokinon that comes in an MFT mount. The DSX continues the line with the same multilayer coating process, industry-standard geared focus and iris rings, and fast T1.5 aperture, and it adds a 9-blade iris for beautiful soft bokeh, weather sealing to keep the moisture out, and focal lengths on both sides for added versatility for focus pullers.

This 50mm lens produces a 23.6° coverage when used with Micro Four Thirds cameras. Hybrid aspherical lenses render sharply defined images with a minimum of distortion and chromatic aberrations, with a minimum focus distance of about 1.5' from the lens. The 9-blade iris also allows you to create up to a stunning 18-ray starburst when you're stopped all the way down.

A removable petal-shaped lens hood provides flare protection when shooting without a matte box, and the lens' threaded front accepts a 77mm filter ring.

As well as delivering the beloved image quality and fast T-stop values of the existing DS series, the high-speed DSX models now have weather sealing, nine aperture blades, and focal lengths that are visible on both sides for more professional use.
The DSX range is highly versatile and available in Canon EF, Sony E, Canon RF, and MFT mounts.
Ultra Multi-Coated lenses minimize flare and ghosting, and the lenses are color matched to a standard eliminating the need to acquire an entire set of lenses at the same time.
Lenses in the Rokinon DSX high-speed cine lens series share common focus and iris gear ring positions, which speeds up lens changes as accessories such as follow focus units or iris motors don't have to be repositioned.
Focal lengths and measurements in feet and meters on both sides of the lens.
De-clicked aperture ring for smooth iris pulls.
A minimum focusing distance of about 1.5' allows you to get up close to your subject.
A removable petal-type lens hood provides flare protection without a matte box.

The best lens I have

By Michael
Rated 5 out of 5
Date: 2025-08-04

I'm not a professional on lenses and I know this is not a very expensive lens but, I've bought 2 Rokinon lenses and they are built very well and sturdy, both cine lenses and they work very well for what I'm doing. This 50mm lens is really a nice lens.

Very good lens

No, the Rokinon 50 mm T1.5 DSX High-Speed Cine Lens (EF Mount) does not zoom. The lens is fixed at 50 mm and will focus only. Moreover, the lens stays at a fixed length when focusing and does not rotate..
