I own a Zone VI Type I enlarger with a short column (I believe it's 44 inches). I have a 8x10 and 5x7 head for it. Currently, I print with a Rodenstock Rodagon 240mm lens. I cannot make 11x14 prints from the 5x7 or 16x20 prints from the 8x10, which is what I'd like to do. The 240 does cover the 8x10 but the head just can't go high up enough to make the 4x enlargements that I want as a minimum.
Can someone recommend a lens that will give me the 4x enlargements from 5x7 and 8x10 negatives that I want?
