[Author Prev] [Author Next] [Thread Prev] [Thread Next] [Author Index] [Topic Index] [Home] [Search]I have an Omega D2 enlarger and 135mm, 105mm, 80mm and 50mm lenses. The 105mm is a Rodenstock and the others are Schneider Companons. It seems most I get the best enlarging range by using the 50mm for 35mm negatives, the 80mm for 6X6 negatives, the 105mm for 6X9 negatives and the 135mm for 4X5 negatives. I am enlarging for 8X10 and frequently cropping from a much larger projection. Should I be doing something differently?
