I bought the 75mm originally from BH Photo. I'd call it mint. It doesn't have any marks on it or on the glass. Comes with both caps, leather pouch, and both boxes. Asking $3400.
The 90mm isn't mint, but is in good condition. I bought it used from CameraWest who rated it an A-. It has a few rub marks on it, and a couple of slight marks on the front element. Asking $3000.
