Stigmatic lens Series 2 by J.H. Dallmeyer London. F.6 5.3 f.1. This lens consists of two dissimilar combinations either of which can be used alone, so that lenses of three different focal lengths are available. The complete lens when used at full aperture covers a negative 8x5 with full margin for rising front. With smaller stops it forms an excellent wide angle lens covering a field of 85 degrees. The front and back combinations have focal lengths respectively twice and 11/2 x the focal length of the complete lens. With lever operated iris diaphragm.
