I want to buy a new enlarger in order to make B&W prints as big as 16x20. I have the possibility to buy the following one, that I understand it is a very good enlarger: - Durst M805, with Bimacon 75. I have not seen this enlarger yet, as it is far from my city. These are my questions: 1.- Could I print 35 mm and 6x6 negatives with this enlarger, without buying anything else? 2.- What is Bimacon 75? 3.- are there negatives carrier glassless for both 35 mm and 6x6 format? 4.- Is this enlarger a good option, or would you prefer a diffusion one? Thanks for your comments, Henry.
