Related Questions and Answers

Q: 1. I am considering purchasing this for cinema and astrophotograpy. Does the cine version focus confirm like the photo version?

A: The primary difference between the still and cine lenses made under the Samyang/Rokinon brand names is the barrel. Still lenses have vertical scales and no gears. Cine lenses have horizontal scales and gears. The image quality of the color and sharpness is remarkable considering their cost. These would be excellent for cine use. For astrophotography, I would be of the opinion that the corners might have chromatic aberration and coma. This would have to be tested.

Q: 2. Using this lens with Matte Box, like a Tilta Mirage, will I get some vignetting?

Q: 3. What benefits, if any, would there be if I purchased the canon mount and used it on a Fuji XH2S with the metabones speedbooster?

A: The Metabones Canon EF lens to Fuji X-mount adapter would preserve the wide angle of the IRIX 30mm T1.5 Cine Lens as well as boost low light performance by 1 stop when used on crop sensor cameras like the Fuji XH2S. When using the IRIX 30mm lens without a speedbooster the lens would provide a 45mm view. When using the speedbooster the view would be 32mm.
