Rokinon 20mm T1.9 Cine DS Reviews

I bought this lens to try out. I used it and loved it. Video looks great and the image is very sharp.

Excellent Lens!

We recently purchased a Canon 6D mark II and I wished to do video recordings but needed a wider lens. This one covers an area of 92 degrees. We found it a great lens for the videos without any grey areas, out of focus areas, no aberrations or any other issues. With enough light, we set it at F-8, or higher, the range at 5 feet and everything was in focus and sharp! It worked well for close-up shots. With low light, setting it at F 1.9 to 2.8 produced great images. Overall, it's a great lens and we are looking at adding more Rokinon lens in future.

Is this essentially the same lens as the 20mm ...

Is this essentially the same lens as the 20mm f1.8, but for Cine?
Asked by: Stanley
If you are referring to BH #RO2018CES then yes, optically it is pretty much the same lens. The difference is the Cinema version has gear rings included and a de-clicked aperture.
