Caldwell Photographic 120mm f/4.5 Macro UV-IR Apochromat

[Abbazz]

Here's a excerpt from the brochure of what looks like a very interesting lens (especially for our distinguished friend kds315*):

The Caldwell Photographic 120mm f/4.5 Macro UV-IR Apochromat is an innovative view/technical camera lens that incorporates both floating element and advanced UV-VIS-IR apochromatic color correction technology. Six ED glass elements and one aspheric element are used to achieve an unprecedented level of performance for multispectral documentation, forensics, scientific imaging, and fine-art photography. After setting focus in visible light, no refocusing is necessary for either ultraviolet or infrared imaging, thus enabling extremely precise color channel registration in multispectral applications. The excellent color correction is also valuable in visible light photography because it completely eliminates the purple fringing suffered by other lenses in high contrast outdoor scenes. The adjustable floating element, unique among view camera lenses, ensures superb optical correction at all object distances.

Six ED elements!
