Nikon and Tamron Patent Teleconverters with Built-In Image Stabilization

 

Canon might be rolling out a new Image Stabilized lens with a built-in teleconverter, but Tamron and Nikon seem to have image-stabilization/vibration-reduction tricks up their sleeve as well. Apparently in the early 2000s both Nikon and Tamron filed patents for teleconverters with image stabilization baked right in. Tamron’s was for a standard unit that sits between the lens and the camera body, while Nikon’s was for a unit that sits in front of the lens.

    Here is a similar story

    A front teleconverter lens system having superb optical performance with less production of aberration in spite of its compactness. The front teleconverter lens system includes, in order from an object, a first lens group having positive refractive power, and a second lens group having negative refractive power, and forming an afocal optical system. A diffractive optical surface is arranged in at least one of the first lens group and the second lens group. The conditional expression 1.2<φF/φR<10 is satisfied, where φF denotes the effective diameter of the most object side lens surface of the first lens group, and φR denotes the effective diameter of the most image side lens surface of the second lens group.
