Status: Sold out. There are no plans to make any more at this time. The following is just FYI.This is a short threaded tube used to reverse mount a lens (using its filter threads) onto the Bronica 57x1mm threaded mount. Lenses are usually reverse mounted when magnifications are greater than 1:1 because the lens will perform better when reversed.This adapter has the 57mm diameter by 1mm pitch threads at one end and standard 58mm filter threads (58mm dia x 0.75mm pitch) at the other. Using your own step up or step down rings you can mount lenses with other size filter threads.
