I have a new 6x9 view camera and am trying to set up a 3 lens kit. I am interested in what focal length in either the 4x5 or 6x9 format you conside r your favorite for portrait work. My current lenses are 55mm & 100mm. Also, is there a lens to complete my "kit" that you think would be best for both portrait and landscape. Feel free to recommend a particular lens. Thanks to all the fine people on this enjoyable LF forum for your opinions.
