Recently I've been offered up two great deals on each of these lenses, and I'm really not sure which way to lean. I can't ignore all the reviews of the Rokinon saying how sharp it is, but the full time manual would definitely fall behind compared to the Canon. As far as image quality goes, I've heard a lot of stories of the 50mm, some good, some not so much. I have the 1.8 and the AF is a killer. I'd most likely be using either lens for car shots and as a walk around prime. Having the 50 1.8 already, should I go for the 85 and give it a whirl, or should I upgrade and go 1.4? Anybody have both and can compare?
