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.

Delivery:

• Adapter to T2 with screw-in thread for the 2.7x Düring Barlow
• Adapter from T2 to 1¼" with brass ring clamp
• Packaging
