I've got a Durst L1200 with a Femoneg carrier. I've been looking for over a year for a Femoneg AM carrier (the version that shows the whole neg when printing 4x5), and have so far not seen any for sale. I contacted Jensen Optical / Durst Pro USA and they said they can convert my carrier to an AM version. This is a quote from them: If you want to send us your EUROPE Femoneg we can modify it to become an AM Femoneg. If you look at the light opening closely you will see a lip all around the opening. The only difference between AM and EU is that lip being removed in the AM." Has anyone tried this? Any downsides to doing this? Seems like a great option, and pretty reasonable to do as well.
