ABSTRACT:
A telephoto lens is provided, in succession from the object side to the image surface side, with a first lens component having a positive refractive power and a second lens component having a negative refractive power. At least one curved lens surface of the second lens component is inclined relative to the optic axis to thereby deflect the image. Particularly the lens surface which near the image surface is inclined.
