If you want coverage with movements on your 6x9 your lenses should be able to cope. If you are using 4x5 you might consider selling one or even both lenses and buying a 1950's Symmar 150. These are convertible lenses. You get two lenses in one. Out of the box it's a 150mm lens, take off the front element and you have a 265mm lens. Very useful if you want to save space and weight.
