I agree, the 75ARD1 has a flatter field than the Scitex. I don't know the construction of the Scitex lenses, and have not been able to find much info on them. Conveniently they have M39 threads like a typical enlarger lens. It looks like they typically sell for around $100, when available. There are 3 for sale by an ebay.com, and the seller is in Israel. I seem locked-out from the auction for some reason...Ray
