If the main 6½" double condenser lens assembly on your Omega 4x5 condenser enlarger has been damaged or is missing, this is the proper replacement. The assembly consists of the two 6½" condenser lenses, the condenser housing or "spinning", and the lens spacer. The photo is of an early version with a brushed aluminum finish on the condenser tube. New assemblies will have a black paint finish on the tube. The used condenser assemblies are certified to be in perfect working condition. The metal parts have minor cosmetic marks that will not affect performance or, ultimately, the image. Used sets will be supplied in brushed aluminum finish, please inquire if you would prefer the black version.
