Q: 7. Can you tell me the difference between this and the Rokinon version... apart from the $1 price difference!I know it's a different choice of lens options, but is the image quality very different to the Tokina 11-16? I can't find a direct comparison/website that has a review of both (so would run the same tests).

A: Rokinon is the makers' brand (ROK for Republic of Korea), Samyang is a second brand of the same maker. The image quality of both the Samyang 10mm and Tokina 11-16 are very good, though the Tokina lens will give you more versatility if you wanted to have zoom.
