The Pentax XW eyepieces have a thread around the eye lens which one can use to attach a camera. Where do I go to get the rings that screw onto the Pentax XW eyepieces which allows the attachment of a T-Ring?
I would recommand purchasing stepdown rings at Adorama or B&H video on the net. Or on the E-Bay site ( Just make a search for step-down rings) and you will find asiatic makers with very low prices.
HI can popper. I imagine you refer to a T mount to 43mm step ring. Look in here.
