This product is a conversion of your 30mm Bausch & Lomb lens to Wireform™ movement in compact metalwork.
Image shown is of the 35mm however the 30mm will be physically very similar.
All the Van Diemen Wireform™ Bausch & Lomb conversions have uniform 100mm fronts with built in focus and iris gears.
This is a full new movement and not a simple remount.
Positive end stops are fitted for focus and iris movements.
The units are all internal focus for ease of accessory fitting.
The lenses do not grow in length when pulling focus the focus gear is therefore static.
30mm 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.
