I just held the lens in front a 50mm on my 550d and i can see the edges, I guess I'll need a longer lens to avoid this.
How about a wide angle adapter screwed into the front of the anamorphic? Do you know what diameter the front screw thread is?
With regard to closeups, I see people are using diopters. Would a set of these mean the anamorphic stays on one lens and then you screw on a diopter when you want a closeup?
Sorry for all the questions!
