    Leica 21mm F4.0 Super Angulon R, IWF, full 24 x 36 coverage Wireform™ conversion.

    This is an ultra wide angle Leica optic. After conversion this becomes a close focus lens with a Macro capability but does not reach full 1:1. It does, however, retain all the features of a standard speed lens. This versatility is possible because of the patented Wireform™ variable pitch lens movement incorporated in the construction. An additional characteristic of this lens is its light weight, a feature made possible by the patented mechanical design. The combination of these characteristics make this lens particularly suitable for applications where weight and precise control of focus are important,for example with camera stabilization equipment and hand held use. All the Leica range IWF conversions benefit from internal focus and are fully geared for motorization. Each focal length has a separately computed focus helix to achieve the best possible focus scale for the particular focal length now using the inverted Wireform™  design (IWF).

    Van Diemen Lenses are assembled to client order in mount of clients choice and scaled metres or feet. Other lens mounts may be possible please contact us for more information.

    All Van Diemen Wireform™ conversions are now supplied with dual iris scales as a standard feature and uniform 114mm front diameter, however, can also supply other larger diameters.

     

    Lenses are supplied in PL or LPL mount with other options available on request.
