Hi Ira,

I think he's referring to the Nikon TC17 ED (?) which is an add on auxillary lens that screws into the filter threads. It's actually an excellent TC, with ED glass, but is pretty heavy and expensive (@ $360). They are made to extend the reach of fixed lens cameras.

Unlike TCs that fit between the lens and the camera, these TCs do not change the effective aperture of the main lens (they have a significantly larger objective diameter, and gather more light). They can, however, cause problems with lenses that don't have internal focusing, as they add a significant amount of weight that now needs to be moved by the focusing motor.

The Nikon is probably the best one made, but IIRC, all of them will cause some increased CA and PF, and they also will reduce sharpness and contrast to some degree.

Scott
Thanks for clearing that up.

Ira
