Wollensak SER. Raptar Telephoto 15-inch (381mm) f/5.6 large format lens in an Alphax Synchromatic shutter. Includes its retaining ring and both front and rear caps. The rear mounting thread measures approximately 66mm; please confirm compatibility with your lens board before purchasing. The glass is clean and clear with only a few internal dust particles. Aperture adjustment operates smoothly. The shutter speed selector has just a slight stiffness but remains fully functional. All shutter speeds have been tested and sound correct by ear. The shutter features marked speeds from one second through 1/50 second, plus Bulb and Time settings, with X/M flash synchronization selection. The exterior shows age-related finish wear and handling marks. A classic long-focus option for a compatible large format camera setup. Please examine photos carefully for condition and mounting details.
