Leon this is a full frame and i had a 0.8 reducer/flattner in the ED80.
The 40D is a 10.2Mp camera and that is why i get a smaller field of view than you.
Ah, I see, I did believe you, I just didn' think of that. I just posted my effort from last night, and have to wonder if those extra sub frames really make that much difference, see what you think, Martin
