I have a 6X9 camera and I like to use it for extreme close-up work with flowers. Currently, I'm using a Rodenstock Apo-Macro-Sironar f5.6/120mm. Would I be bett er served by using a telephoto or compact telephoto lens. My camera is an Ebony SV23 and the bellows min/max75mm/420mm. I want to get 1:1 to 2:1,
