A Tele-Arton 180mm is NOT a good choise for 4x5". Any tele-anything at all is NOT a good choise for a first LF lens, since you will get headaches immediately on trying to use movements.
A simple good "standard" Plasmat-type lens, in focal length from 150mm to 210mm, is a much better start. The Schneider Symmar is one such.
Longer Plasmats, like a 210mm, are big and heavy. Get a 150mm if you find one for below $200. They provide sufficient coverage to play with movements, sufficient speed that you can see what you are doing on the ground glass, and give very decent performance for very little muney - usually LESS than the shutter would cost on its own.
