For those of you who have dreams of using your Topcor lens on a lens turbo speed booster I am here to crush your dreams. The fotasy EF adapter fits great to the Topcor lens. However, the pin that moves with aperture changes is thicker than the adapter and will not mount to a lens turbo or probably any other speed booster. It would have to be ground. |
