If you have an Alphax or Betax shutter, congratulations! You own one of the Wollensak Optical Company’s finest products. Manufactured between 1921 and 1972, this classic line of leaf shutters is rugged, reliable and extremely well made. Properly serviced, your Alphax and Betax shutters can continue serving your photographic vision for decades to come.

At Alphax Betax Shutter Services, I offer full service parts, repairs, and replacements for your Alphax and Betax shutters at a reasonable cost. In addition, I offer limited CLA services on Wollensak’s Studio shutters and iris diaphragm barrels. This site also provides resources to learn more about Wollensak lenses and shutters, Wollensak history, Wollensak serial numbers, and browse original Wollensak catalogs and publications. I sometimes offer a few Wollensak products for sale in the shop.
