Like I said before, the petals have to be cut on the Samyang to get a decent image on full frame...and its still not full frame...but its also more like 200+ degrees fov at that point...chk my blog reference earlier in this thread..
I just burned the hood of my Samyang with a hot soldering iron....I first covered the lens with tape and paper so as not to damage it...Looks ugly but works great..
