I just purchased a LOMO 35mm square front anamorphic with the original 35mm taking lens. I will have two LOMO prime lenses in 50mm and 75mm focal lengths arriving shortly. Will I be able to use either of these lenses as a taking lens? Can I have anamorphic 35mm, 50mm and 75mm just by replacing the taking lens and keeping the front 35mm anamorphic attachment?
