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).
