I am considering getting into the 4x5 realm at a entry level and as cheaply as possible. My darkroom enlargers are all designed to handle the 35 mm to 120 format. Is there any way short of purchasing new enlargers to utilize this format with my existing equipment. My desires to enter large format would not allow for a camera purchase and a new enlarger purchase. Please give me your thoughts on this subject and what you have known others to do in order to blend this format along with darkroom wishes.
