We offer you a 2-part adapter kit to use your 2.7x Düring ED Barlow lens both visually and photographically.
Our 2-part adapter is designed photovisually, visually with optimal distance with APM-Deluxe centering clamp. The upper part is 55mm long and can be unscrewed, so that a T2 thread (M42 x 0.75) appears and cameras with a total back focus of 55mm (DSLR + T2 ring) can be used.
The T2 adapter (M42x0.75) has the matching screw-in thread for the Barlow element. From the T2 thread it is exactly 55mm to the optimal focus position.
ATTENTION: The Barlow element is NOT included in the delivery.
