6 element, 5 group flat field optical design is housed in a fairly long barrel about twice the length of conventional 4 element 2X converters. Designed for Tamron lenses with a focal length of 90mm and longer, but seems to work very well with tamron lenses of shorter focal length like the SP 35-80mm. Has its own aperture scale to indicate effective change to F stop value.
