| New 4"x 4" solid aluminum lens board for all Beseler 4x5 enlargers, including the 45M, 45MX, 45MCRX, 45MXII, 45MXT, 45V-XL, and CB7. These lens boards are threaded to accept lenses with 42mm mounting thread, such as certain Schneider Componon-S 135 and 150mm lenses. Please check the thread diameter of your lens. Lenses can be mounted directly on the lens board without requiring a jam nut, retaining ring or mounting flange. |
