Small Metal Work

These conversions are small, lightweight and robust; made completely from anodised metal components.

Our Small Metalwork lens conversions are rehoused in a lightweight, durable metal housing. These conversions are compatible with most prime lenses and use our patented variable pitch Wireform™ system to provide a very smooth focusing movement with solid end stops and industry standard gearing for motorisation.

These lens conversions are all provided with internal focusing and a static 100mm front diameter ideal for mounting accessories. All Van Diemen conversions are supplied with dual iris scales and PL mounting as standard, with other mounting and engraving options available.

Please contact us to enquire if we can convert your lens.
