Yes, I too have the 21 1/4 " Ektanon for the 8x20. It is a great lens. Coupled with my 14" Gerogon I have two great lenses for this format at a fraction of the cost of an Artar. I did steal a mint Ilex 21 1/4" for the 11x14 and it is sharp as hell also. Now everyone go back to sleep and we never had this conversation....right!!!
