100mm fixed fronts for easy attatchment of accessories.

Front diameter of 100mm is common on all Bausch & Lomb Wireform™ conversions.

This is a full new Wireform™ movement not a simple remount.

Super Baltar

50mm F2.0 Wireform™ lens

A full conversion to PL mount.

All the original thread based lens movement is replaced using the Wireform™ lens movement developed by Van Diemen Films.

The specially chosen pitch of the focus movement generates well-spaced focus scales right down to the macro end.

The lens has solid end stops at iris position fully open and fully closed. The focus movement also has solid end stops at each end of the full movement. The lens has industry standard drive gears for focus and iris at a fixed element throughout the series. 

All Van Diemen Wireform™ conversions are now supplied with dual iris scales as a standard feature and uniform 100mm front diameter, however, can also supply other larger diameters on request.
