question

Is there no difference between this and the Samyang? I see that this one has the inclusion of IF in the name for Internal Focus . That sounds like a made up word for manual focus though. Am I right? A big difference I see is $60-$100 which I'd like to save.
Asked by: Robert V.
There is no difference between the two lenses. Rokinon and Samyang are both made in the same factory by the same company.

question

Would it fit Canon 70D mount?
Asked by: Mykolas G.
Yes. Fits full and aps-c canon frames (EF mount). I have it on the 70D myself and coupled with magic lantern to help with focusing makes it a killer lens!

will the aperture remain wide open when not taking a photo, only going to the selected setting when the shutter is pressed?
Asked by: Liam
No, the aperture will adjust according to the aperture that is set on the aperture ring of the Rokinon 50mm f/1.4 AS IF UMC Lens for Canon EF Mount. The aperture does not stop down like in an auto exposure lens. This is a fully manually exposure lens, so the aperture only changes when you change the aperture ring.
