Early Contax lenses for the early 1930's Contax I have black trim. Clean finder glass but slight marks on top edge It was just released when this camera was produced, but the serial number 3424669 is from '51/'52, so it was probably not delivered with this camera. The Carl Zeiss Planar 1,7 / 50 T * is an excellent fast fifty lens with manual focusing. The Zeiss interchangeable lenses with Contax/Yashica mount cover the focal length range from 15 to 1000mm, all providing extra-high speed for most convenient application even in adverse light situations.
And the serial number on the 50 1.4 seems.
