Sorry, this item sold. Have steambaby make something just for you, or try these other items:
This is the latest version of the iris aperture goggle set that has a magnifier stem on one eye piece and then the iris aperture set into the other side. On this one magnifiers are set on the right and the iris is on the left.
As you can see, the iris has continuous motion and is actuated by a pin lever set into a slot on the side of the goggle. The iris can go from almost completely closed to a full size opening, and works very much like the "f-stop" feature of a camera. As the aperture is made smaller, your perception of depth of field is enhanced slightly...like cupping your hand around your eye when looking at something far away. The effect is slight but is present.
The iris wow factor is just plain badass. You will love this goggle. Operation of the iris lever is silky smooth. Iris has 16 leaves on visible pivot pins.
Leather is a waxed deep brown and very tough. It distresses well and is supple and comfortable to wear. Brass buckle, rims and rivets.
One of the very best goggles I have ever made!
Own the Astin Martin or Lotus of goggles!
