FA: Mount many lenses on your view camera with this Universal Iris device

This handy, well-made device enables you to temporarily mount any lens
of 3 inches in diameter or smaller onto a view camera.

Switch easily between lenses -- barrel lenses or even shuttered lenses
-- or experiment with mounting unusual lenses on your camera without
mounting permanently.

This Iris has two knobs - one to open and close the iris blades, and
another to lock them in place. It comes attached to a 6-inch mahogany
lensboard with rounded corners (Deardorff?), but can be easily
re-mounted to the lensboard of your choice with just four wood screws.
The action is smooth and the numerous blades form a very round circle.
