Adapted to canon EF / EFS mount. Focus works, IRIS IS STUCK OPEN. No fungus. There is some very minor haze and maybe some minor interior dust, this seems to have no impact on the image, please refer to sample images. (Sample images in the listing, do note that they are unedited sharpness test out photos out the window.) This is a full frame lens, which is also a fully manual lens, meaning that the operator manually  changes focus and iris, rather than the camera.
