Rokinon 50mm T1.5 Cine DS Lens for Canon EF
This manual focus prime lens is built for Canon EF mount cinema and video work. Its fast T1.5 aperture suits low-light shooting and shallow depth of field control. The de-clicked aperture ring and geared focus ring integrate directly with standard follow-focus systems. It is not for photographers who require autofocus or electronic aperture control.
Thermal performance and power draw
The lens is a passive optical device with no electronics, so it generates no heat and draws no power during operation. There are no fans or active cooling components to produce noise. Silent manual adjustments keep the acoustic profile at zero. It is not for users who expect active thermal management or powered features.
Build quality and daily handling
A nine-element optical design with internal focusing minimises breathing while maintaining a consistent angle of view. An 8-blade iris produces smooth bokeh, and laterally printed distance and aperture markings allow easy focus-puller access. Industry-standard gearing on both rings fits common cinema accessories. It is not for shooters who need weather sealing or electronic lens communication.

Questions about this item
How do I attach this Rokinon 50mm T1.5 Cine DS lens to my Canon EF camera body?
Align the red mounting index on the lens barrel with the matching mark on the Canon EF mount, then twist clockwise until it locks with a click.
What part of this lens will need maintenance first after heavy use?
The manual focus helicoid and the geared focus ring may develop stiffness over time; periodic cleaning and light re-lubrication of the helicoid threads keeps rotation smooth.
What optical limit appears first when I shoot wide open at T1.5 for extended takes?
At T1.5 the shallow depth of field is only fractions of an inch, so precise focus holding becomes the practical limit before any optical aberration dominates.
