Rodenstock Sironar-N 210mm 5.6 MC Copal1 Lens SN 10553377 PERFECT CONDITION $365 The Sironar-N is the direct predecessor to the current APO Sironar-N. In fact, all the mechanical specs and basic design is unchanged between the two lines. At the time it was a change in name and labeling only. The MC refers to multi-coated. The Rodenstock 210mm f/5.6 Sironar-N Lens is a standard lens for the 5x7 format, or a slightly long lens for the 4x5 format. Designed for universal use, it provides high image reproduction quality and its applications are practically limitless. Its strengths can be seen when complex, fine structures in the adjustment range have to be reproduced. The 72° angle of coverage of the 210mm Sironar-N permits generous shifts of at least 83mm in the 4x5 format and 53mm in 5x7, allowing more control over the large format image and less limitations upon the creative capacity of the photographer.
