Excellect example of an ultimate portrait lense. Carl Zeiss Planar T* 85mm f1.4 AEG Contax Yashica mount. Optics, clean and clear. Will work with most DSLR's and mirrorless digital with the right adapter.
The Carl Zeiss Planar lens is the most successful camera lens design ever created. This nearly symmetrical layout provides the lens designer with numerous means to correct aberrations extraordinarily well, even at wide open apertures. This design is the ideal basis for high-performance lenses with great color correction, high speed, flat image plane (this is where the name Planar originates) and low distortion. The Planar design is the basis for nearly all professional "workhorse" lenses on the earth and used in space today.
