I've got an old Durst 609 enlarger, made for medium format up to 6x9 but also capable of enlarging 35mm with the (suggested) accessory "SEZUCO" condenser lens. I have been able to enlarge 35mm successfully up to a certain print size but lately have been trouble making larger prints without the Sezuco. I have the opportunity to purchase the condenser lens from a Bogen Super 66, which was designed for 6x6 but capable of 35mm enlargement with it's own additional condenser lens.
Assuming that the lens will fit my machine, should the 6x6---35mm condenser lens provide better 35mm illumination than my Durst 6x9 enlarger does without any additional condenser? Even an improvement would be acceptable until I can find a Sezuco or until I can get a different enlarger altogether.
And please, I know that the real answer is "get a new enlarger", but I'm currently out of work due to an injury. I have a nice stash of paper and chemicals from when I was working regularly and would love to take this recovery time to work on some of my 35mm negatives without significant additional expenditure. The Durst Sezuco lens is apparently a mythical beast, proving extremely difficult to procure. I'm hoping to at least gain improved illumination.
If anyone has an idea, even theoretical, it would be appreciated.
